Travel Blogging and Photo Editing

Weaver's hand
Camera: Panasonic DMC-GX8 | Date: 17-02-2017 11:39 | Resolution: 5184 x 3456 | ISO: 1600 | Exp. bias: -66/100 EV | Exp. Time: 1/40s | Aperture: 4.5 | Focal Length: 30.0mm | Location: Weaving village at In Paw Khone | State/Province: Inbawhkon, Shan | See map | Lens: LUMIX G VARIO 12-35/F2.8

I’ve been asked a number of times recently how I manage to write my blog during the often hectic schedule of my trips. It is sometimes a challenge, but it’s something that I want to do, and so I make it a priority for any "down time". I don’t see it as a chore, but as a way of enhancing my enjoyment, re-living the best experiences, working through any frustrations, and building valuable memories. If I’m travelling without Frances then there’s a lot of overlap with my report home, and if we’re travelling together then drafting the blog has become an enjoyable joint activity for coffee stops and dinner times.

That said, there are a few tricks to make the task manageable, and I’m happy to pass on some of those I have developed.

There’s no great magic to the writing. The main ingredient is practice. However I do spend quite a lot of time thinking through what to say about a day, trying to draft suitable paragraphs in my mind. If it was good enough for Gideon it’s good enough for me :). It is useful to capture ideas and even draft words whenever you get an opportunity, even on the go: travel time in buses and coffee stops are ideal. I just start drafting an email to myself on my phone, which can be saved at any time, reopened to add more as the day goes on, and sent before I start writing the blog.

The other important tool is a blogging app on your device which works offline and can save multiple drafts locally. I use the excellent Microsoft Live Writer on my PC, and the WordPress app on my phone and tablet, but any decent text editor would do. I would strongly counsel against trying to do travel blogging directly onto an online service – you will just be too obstructed by connectivity challenges.

Images are the other part of the equation. It’s very easy to be overwhelmed by the sheer volume of images, especially if you shoot prolifically like I tend to do, and if you have a relatively slow processing workflow. The first trick is to shoot RAW+JPG, so you always have something which you can share and post, even if it’s not perfect. As I observed in a previous post, you don’t need perfect in this context, and it would be rare if you didn’t from a day’s shooting have a least one image good enough in camera to share.

However, as long as I have at least some time, I do try to perform a basic edit (filter) on my shots, and process at least the one or two I want to publish to my blog. That requires a robust but quick and efficient workflow. Different photographers work different ways, but the following describes mine.

Importantly, I don’t use LightRoom or the image management features in Photoshop. Neither do I use Capture One’s catalogue features. All my image management takes place directly in Windows, supported by the excellent XnView and a few tools of my own making. I find that this is both quicker, and puts me in direct control of the process, rather than at the mercy of a model which might not suit.

The first step is to copy (not move) the images off the memory card. If I have only used one card in a session, I find it perfectly adequate to just connect the camera via USB – this works quite quickly, and avoids fiddling with card readers. As long as I have sufficient cards I don’t re-format them until I’m home (just in case something happens to the PC), nor do I do much in-camera deleting, which is very cumbersome.

In terms of organisation I have a top-level directory on each laptop called "Pictures" under which is a directory called "Incoming". This is synchronised across all my computers, and holds all "work in progress". Under that I have two master directories for each year or major trip, and then subdirectories for each event. So for Myanmar I will have top level directories called "Myanmar 2017" (for output files and fully-processed originals) and "Myanmar 2017 – Incoming" (for work in progress). Under the latter I would typically have a directory for the images from each day’s shooting, e.g. "Lake Inle Day 2". On the "output" side I will typically have a directory for each location, plus one for all the originals (RAW files and Capture One settings), but I could easily also end up with others for video, and particular events or topics such as the group.

Having copied the pictures over to the right working directory, I fire up XnView. The first step is to run a batch rename process which sets each image filename to my standard, which includes the date (in YYYYMMDD format), the camera and the number assigned by the camera, so all shots from a given camera will always sort alphabetically in shot order, and I can immediately see when an image was taken and on which camera. After that I run a script which moves all "multi-shot" images into sub-directories by type (I shoot panoramas, HDR, focus blends and 3D images each using a distinct custom mode on the camera) and takes these out of the main editing workflow.

The next step is to "edit" the images, by which I mean filtering out the bad, poor, and very good. Because I have JPG files for each shot, I can set XnView to sort by file type, and quickly scan all the JPG files in full screen mode, tagging each (using shortcut keys) on the following scheme:

  • Two stars means "delete". This is for images which are beyond use: out of focus, blurred, subject not fully in the frame. These will be moved to the wastebasket, and once that’s emptied, they are gone forever.
  • Three stars means "others". This is for images which are technically viable but which I don’t think merit processing. The obvious candidates are things like alternative people shots where the expressions weren’t ideal (but I have a better shot) or where I took a few slightly different compositions and some obviously don’t work. However this is also where I park duplicates or the unwanted frames from high-speed sequences. When I get home the JPGs will be deleted and the RAW files moved to an old external hard drive to free up disk space.
  • Four stars means "OK". This is for technically and compositionally adequate images, albeit which may not be the best, or may need substantial processing work.
  • Five stars means "good". These are the images which leap out at a quick viewing as "yes, that’s going to work".

Having tagged the images in the working folder, I have another script which deletes the two star images, moves the "others", and creates a .XMP file marking the five star images with a colour tag which can be read by Capture One. I can also copy the in-camera JPG versions of the 5 star images as a starting point for my portfolio, although these will be replaced by processed versions later.

The thing about the tagging process is to keep going, quickly, but err on the side of caution (so tag borderline delete as 3 star, and borderline others as 4 star). I can usually work through at an image every one or two seconds, so the first filter of an intensive shoot of 500 images takes less than 20 minutes. At this point I have typically reduced the retained images by 40-60%, but that varies by subject matter and the percentage of rejects can be much higher for challenging subjects such as high-speed action but also people other than professional models, where a lot get rejected for poor expressions. The reason I’ve chosen the image at the top is that I love trying to capture hands at work, but that’s another subject with a high "miss" rate. I also find that I fairly consistently mark about 4-5% of shots as 5 star.

I don’t just delete the "others", because there is the occasional case where my selected shot of a group turns out to have a major flaw, and it’s worth reviewing the options. More importantly, for family events, weddings and the like there’s the occasional "didn’t anyone take a picture of Aunty Ethel?" I rescued a friend of mine from a serious family bust-up when it emerged that the official photographer at his wedding hadn’t taken a single photo of my friend, the groom’s parents! On the case, I found a shot in "others" which after processing kept everyone happy.

At this point, and only then, I start up Capture One and navigate to the target working directory. It takes a minute or two to perform its first scan, and then I can change the sort order to "colour tag", and there are the best of the day’s images, right at the top of the list ready to select a couple for the blog and process them. 90% of the time I restrict processing changes to the crop and exposure (levels and curves) – I wouldn’t usually select for the blog any image needing more than that. Finish the words, and I’m ready to post my blog.

From plugging in the camera to posting typically takes around an hour. There’s some scope for multi-tasking, so I can work on the words (or get a cup of tea) while the images are downloading from the camera, or while posting the images to my website (which in my case is a separate step from posting the blog). As a by-product, I have performed my first edit on the shoot, and have more or less the best images prioritised for further processing.

And I have an enduring and sharable record of what I did on my holidays!

The Perfect is the Enemy of the Good

Buddha at Pa-Hto-Thar-Myar Pagoda, camera lying on bag!
Camera: Panasonic DMC-GX8 | Date: 11-02-2017 12:14 | Resolution: 4072 x 5429 | ISO: 400 | Exp. bias: 0.66 EV | Exp. Time: 1.6s | Aperture: 4.5 | Focal Length: 7.0mm | Location: Pa-Hto-Thar-Myar Pagoda | State/Province: Nyaung-U, Mandalay | See map | Lens: LUMIX G VARIO 7-14/F4.0

The Perfect is the Enemy of the Good. I’m not sure who first explained this to me, but I’m pretty sure it was my school metalwork teacher, Mr Bickle. Physically and vocally he was a cross between Nigel Green and Brian Blessed, and the rumour that he had been a Regimental Sergeant Major during the war was perfectly credible, especially when he was controlling a vast playing field full of chatty children without benefit of a bell or megaphone. However behind the forbidding exterior was a kindly man and a good teacher. When my first attempt at enamel work went a bit wrong, and some of the enamel ended up on the rear of the spoon, I was very upset. He kindly pointed out that it was still a good effort, and the flaw "added character". My mother, another teacher, agreed, and the spoon is still on her kitchen windowsill 45 years later.

I learned an important lesson: things don’t need to be perfect to be "good enough", and it’s better to move on and do something else good than to agonise over imperfections.

I also quickly found that this is a good exam strategy: 16/20 in all five questions is potentially top marks, whereas 20/20 in one and insufficient time for the others could mean a failure. The same is true in some (not all) sports: the strongman who is second in every event may go home with the title.

Later, in my training as a physicist and engineer, I learned a related lesson. There’s no such thing as an exact measurement or a perfectly accurate construction. I learned to think in terms of errors, variances and tolerances, and to understand their net effect on an overall result. When in my late 20s I did some formal Quality Management training the same message emerged a different way: in industrial QA you’re most interested in ensuring that all output meets a defined, measureable standard, and the last thing you want is an individual perfectionist obstructing the process.

Seeking perfection can easily lead to a very low (if high quality) output, and missed opportunities. It also risks absolute failure, as perfectionists often have no "Plan B" and limited if any ability to adapt to changing circumstances. "Very good", on the other hand, is an easy bedfellow with high productivity and planning for contingencies and changes.

I adopt this view in pretty much everything I do: professional work, hobbies, DIY, commercial relationships, entertainment. I hold myself and others to high standards, but I have learned to be tolerant of the odd imperfection. This does mean living with the occasional annoying wrinkle, but I judge that to be an acceptable compromise within overall achievement and satisfaction. Practice, criticism (from self and others) and active continuous improvement are still essential, but I expect them to make me better, not perfect.

The trick, of course, is to define and quantify what is "good enough". I then expect important deficiencies against such a target to be rectified promptly, correctly and completely. In my own work, this means allowing some room for change and correction, whether it’s circulating an early draft of a document to key reviewers, or making sure that I can easily reach plumbing pipework. If something must be "set in stone" then it has to be right, and whatever early checks and tests are possible are essential, but it’s much better to understand and allow for change and adjustment.

In the work of others, it means setting or understanding appropriate standards, and then living by them. After I had my car resprayed, I noticed a small run in the paint on the bonnet. Would I prefer this hadn’t happened? Yes. Does it prevent me enjoying my unique car and cheerfully recommending the guys who did the work? No. Professionally I can and will be highly critical of sloppy, incomplete or inaccurate work, but I will be understanding of odd errors in presentation or detail, providing that they don’t affect the overall result or number too many (which is in turn another indicator of poor underlying quality).

So why have I written this now, why have I tagged it as part of my Myanmar photo blog, and why is there a picture of the Buddha at the top? In photography, there are those who seek to create a small number of "perfect" images. They can get very upset if circumstances prevent them from doing so. My aim is instead to accept the conditions, get a good image if I can, and then move on to the next opportunity. At the Pa-Hto-Thar-Myar Pagoda I (stupidly) arrived without my tripod, and had to get the pictures resting my camera on any convenient support using the self timer to avoid shake, in this case flat on its back on my camera bag on the temple floor. Is this the best possible image from that location? Probably not. Am I happy with it? Yes, and if I have correctly understood Buddhist principles, I think the Buddha would approve as well.

It is in humanity’s interest that in some fields of artistic endeavour, there are those who seek perfection. For the rest of us, perfection is the wrong target.

Myanmar Musings (What Worked and What Didn’t)

Scarf seller at Thaung Yoeu
Camera: Panasonic DMC-GX8 | Date: 15-02-2017 17:37 | Resolution: 3888 x 3888 | ISO: 1600 | Exp. bias: 0 EV | Exp. Time: 1/25s | Aperture: 9.0 | Focal Length: 33.0mm | Location: Thaung Yoeu ladies and pagoda ru | State/Province: Indein, Shan | See map | Lens: LUMIX G VARIO 12-35/F2.8

Well, I’m back! Apart from a mad dash the length of Bangkok airport which got us to our plane to the UK with only a couple of minutes to spare, the flights home were uneventful and timely. Here’s my traditional tail-end blog piece, with a combination of “what worked and what didn’t” and more general musings.

This was a truly inspiring photographic trip, with a combination of great locations, events and people to photograph. We had a very capable “leadership team” who got us to great locations in great light, and the Burmese people were only too happy to participate in the process. No praise can be too high for our local guide, Nay Win Oo (Shine), who is not only a great guide and competent logistician, but has a good feel for what makes great photography, and a real talent for directing the local people as models.

If I have a minor complaint, it’s the observation that the trip was largely focused on interiors and people to the occasional exclusion of landscapes and architecture. I had to declare UDI a couple of times to get a bit more of the latter subject matter in front of my lens. Bhutan was perhaps a better match to my own style, but that didn’t stop this trip being a great source of images.

Cameras and Shot Count

The Panasonic GX8 was the workhorse of the trip, and took approximately 3690 exposures. That’s about 20% higher than either Bhutan or Morocco, both of which were slightly longer trips, and reflects the more “interactive” nature of the photography, with a rather higher discard ratio than normal. As usual the total also includes raw material for quite a lot of multi-exposure images, mainly for 3D and panoramas. I expect to end up with 100-200 images worth sharing, which is about the norm.

I took around 84 stills on the Sony RX100, mainly “grab shots” from the bus, but it came into its own for video, and I have a number of great video clips, more than  on previous trips. I also took a handful of images using the infrared-converted Panasonic GX7, but whether due to the subject matter or the lighting they weren’t terribly inspiring.

I used my Ricoh Theta 360-degree camera several times, mainly in the markets and at the group mealtimes. I’m treating this as “found photography” – I haven’t had much of a look yet at what was captured, and will look forward to exploring the output over time.

My equipment all behaved faultlessly. I used all the lenses a reasonable amount, with the Panasonic 12-35mm doing the lion’s share as expected, but the 7-14mm, 35-100mm and 100-300mm all getting substantial use. I didn’t use the camera on my new Sony Experia Ultra phone, but its excellent GPS was a vast improvement over the Galaxy Note’s poor performance in Bhutan.

I also did not use the Panasonic GX7 which I was carrying as a spare, but was able to lend it as a complete solution to another member of the group when her Canon L Series zoom lens started misbehaving. Having been burned previously I always carry a spare everything, and that’s a lot easier with the diminutive Panasonic kit.

Human Factors

While technology was broadly reliable, human systems were more challenged. The combined effects of the intensive schedule and the expected risk of tummy bugs led to as fairly high attrition rate. At least half the group missed a shoot or a meal, and a couple were quite ill for a couple of days. I was lucky that my own “wobble” was brief and started within a quick walk of a five star hotel. I would advise most travellers to think in terms of “when” not “if”, and definitely avoid all uncooked food.

Hotels and restaurants were clean, and even out and about most washrooms were acceptable. Similarly temple areas were kept clean, with the fact that all shoes are removed at the entrance a clear contributor. The challenge is in the more general areas, especially in the towns and cities, where any surface you touch may also have been touched by many others. Money is a particular challenge. All you can do is to keep sanitising your hands, but also bags, cameras, wallets and other items which you may have to touch with dirty hands.

Our Burmese travel agents certainly did everything they could to reduce stress.  Once we arrived in Burma responsibility for our large luggage and travel documents began and ended with putting our bags outside the room at the appointed time. Then we just got on the bus, walked through the airport picking up a boarding pass as we passed Shine, and that’s about it! I could get used to travelling that way…

With someone else doing the “heavy lifting” (quite literally in the case of my case), you can get around with two phrases and 3 gestures:

  • Minga-la-ba, which is a polite “good day” exchanged between any two people who make eye contact. The choruses in the school and markets were fascinating! This can be used to cover a multitude of sins, and works very well as “please can I take your photograph?”
  • Che-su-ba, which means “thank you”. ‘Nuff said.
  • The smiley face and thumbs up, which work when you’re not close enough to use Minga-la-ba and che-su-ba.
  • A gesture consisting of the left hand held out at table level, palm up, with the right hand held about a foot above it, palm down. This is universally interpreted as “I would like a large Myanman beer, please” 🙂

Burmese Bizarre

Myanmar is a bit bizarre in a number of ways. Let’s start with the name. Myanmar (pronounce “mee…” not “my…”) is a relatively recent invention, and is not universally adopted. It doesn’t help that Aung San Suu Kyi (the popular and de-facto leader) tends to use “Burma” herself, and there’s no common adjective derived from Myanmar, whereas “Burmese” works, and is officially valid if it relates to the dominant ethnic group and language. It wouldn’t surprise me if “Myanmar” goes the way of “Zaire” and “Tanganyika”, and we’re all back to “Burma” in a few years.

The Burmese really do “drive on the wrong side of the road”. In another anti-colonial dictat a few years ago, one of the madder generals decided to change from the British practice, and instructed the country to drive on the right. On it’s own, that’s not a problem. It works fairly well for the Americas and most of Europe. However the Burmese are trying to do it with the same almost completely right-hand-drive vehicle supply as the rest of Asia and Australasia. So all of the drivers are unable to see round corners or larger vehicles in front, and every bus has a “driver’s assistant” who’s main job is to stop passengers being mown down by passing traffic as they disembark into the middle of the road!

At a daily level Myanmar is almost entirely cash-based, with effectively three currencies in circulation. Major tourist transactions are conducted in US Dollars. These must be large denominations and absolutely pristine – they may be rejected for a tiny mark or fold. Next down, most day to day transactions by tourists and the more wealthy are conducted in Kyat (pronounced “Chat”), in round units of 1000 Kyat (about 60p). 10,000K and 5,000K notes tend to also be quite tidy. Transactions with and between the poorer people are in tens or hundreds of Kyat and the money is quite different. It’s absolutely disgusting, clearly and literally passing through a lot of hands in its lifetime. It’s all slightly reminiscent of the two currency system in Cuba, but with one currency used two distinct ways.

Uniquely among the countries I have visited, Myanmar has no international GSM roaming. However we had good straightforward Wifi connectivity at reasonable speeds and without any obvious restrictions at all the hotels and in several other locations. I suspect this is a transitional state, as the enthusiastic adoption of mobile phones in the local population will inevitably drive a standard solution fairly rapidly.

One thing which did amuse me – one of the primary providers of Internet services is a company called SkyNet. Shine say’s they’ve all seen the films, so I’m assuming the founder is a Terminator fan…

The usual Asian approach of throwing people at any problem showed mixed results. Bangkok Airport is an enormous hub trying to run on small site processes which don’t scale just by adding people. The role of “bus driver’s assistant” does find employment for young lads with a helpful attitude but few exams. However we did have one very delayed meal where the problem seemed to be one of short staffing, despite a lot of people milling around the restaurant with nothing to do, most of the order taking, cooking and serving was being done by one or two individuals who were run ragged. It will be interesting to see how the approaches vary as the economy grows.

Guide books describe the food as “a rich fusion of unusual flavours” and “a repertoire of ingredients not found in any other cuisine”. Yeah, right. I’ll admit that I was being a bit cautious and avoided some of the more unusual fish and hot curry dishes, but basically it was Chinese or Thai food with a few local variations (more pineapple), alongside a number of Indian, Italian and Anglo-American favourites. One member of our group survived almost the whole trip on chicken and cashew nuts, and I’ll admit to a couple of pizzas!

To Sum Up

Lovely country, lovely people, great photos, but keep cleaning your hands and stick to the Chinese food (and beer)!

Enlightenment

Inside the Painted Hall at Greenwich. HDR from 3 base images
Camera: Panasonic DMC-GX8 | Date: 25-03-2016 20:35 | ISO: 200 | Exp. Time: 1/80s | Aperture: 6.3 | Focal Length: 23.0mm | Lens: LUMIX G VARIO 12-35/F2.8

I have to confess, this post is a conflation of two fairly separate topics, and I struggled to find a common theme, but I think I’ve just about pulled it off. Apologies if you disagree.

I’m just working through some photos I took last year, including a trip to Greenwich. When I first started using the latest generation of Panasonic cameras and Capture One software, I publicly questioned whether we still needed HDR techniques. The answer, I have discovered, is still very much "yes", but maybe only in more extreme circumstances than in earlier years. The dynamic range between the day-lit buildings outside the Painted Hall, the splashes of direct sunlight inside, and the dark shadows away from that direct lighting was considerable, and no single image could cover them. To process this I took a series of images covering a 4 stop base range, and then applied Capture One’s highlight and shadow correction to them, squeezing probably another two stops in each direction, before feeding into Photomatix to merge into one. I’m pleased with the result, and happy that it justifies keeping those tools in my software "kit".

This post is also a bit of a test of another returning technical capability. I very much mourned the passing of Google Currents in 2012. If you don’t remember, this was a beautiful news and feed reader with two key capabilities: offline working, and presenting the headlines of available stories as a mix of text and highlighted images, in the idiom of a paper magazine. However, Google killed it off in favour of the brain-dead "News-stand" app which has neither of these features. At the time I struggled to find a replacement. Feedly offers roughly equivalent feed management capabilities and equally pretty content presentation, but it doesn’t work offline, which is a key capability for me, as I often catch up on news in low-connectivity environments. The available independent off-line readers were not a great bunch, but I settled on Press, which handled content caching very well but was never very inspiring in terms of the presentation of content, or its reading environment. For reasons I haven’t ascertained, it recently stopped displaying the headline images from my own feed, which is rather annoying.

I have occasionally tried to find a more complete replacement for Currents, and last night, 5 years on, I may finally have found one. It’s called Paperboy, and it may do the trick. Like Press, it runs on top of Feedly to allow common feed management across multiple apps, and it looks like it has similar offline capabilities, but the display and reading environment is much more like the lamented Currents. However, I need to check how it handles my own feed, and that means making sure I have a new post. So that’s the other purpose of this item.

I’ll let you know how it works.

What Are We Losing?

We’ve been watching "The Man In The High Castle". Despite all the horrors of Fascism this depicts, I find the single most perturbing image to be that of a Supersonic Transport, recognisable The Concorde, with a swastika on the tail. Why?

I was proud, am proud, to be of a generation where old allies, old rivals, old enemies could work together to create some of mankind’s greatest engineering achievements. Concorde. The Channel Tunnel. CERN. Suddenly, almost inexplicably, these appear to be icons of mankind’s past, not its current achievement. Great icons of peace they appear unattainable in the new post-truth, me-first reality of 2016+ realpolitic.

Those who voted for Brexit, for Trump, who apologise for Putin need to think and explain. What are we losing, and why?

Dozy Android

I’ve just spent a good couple of hours sorting out a problem with my new phone, which has no good reason to exist. In fairness to Sony, it’s nothing to do with them: the issue sits squarely with Google and yet another "improvement" to Android which turns out to be nothing of the sort.

A watch-based alarm doesn’t work very well for me – my hearing is just not good enough. Seeking to reduce the amount of gadgets I carry, I have therefore for many years relied on phones and their PDA predecessors to fulfil the function of alarm clock, especially when I’m travelling. It’s not a difficult role, and I have not had to complain about it. Until now.

In my normal weekly cycle I don’t have much need for a clock as I wake naturally at about the right time each day. This makes the operation of such a function even more critical, as it has to be absolutely reliable on days which are exceptions, and I don’t get much opportunity to do much advance "testing" of what I assume is something that should "just work". However, I do have the alarm set every day when I’m working away from the home, and although I couldn’t be absolutely sure I was coming to suspect that it wasn’t going off at the right time. The first couple of times I assumed "user error": incorrect settings, volume too low etc., but I had eventually eliminated those, and confirmed the behaviour: the alarm didn’t go off at the programmed time. It went off after I had woken up and clicked the button to wake up my phone’s screen.

This is about as useful as a chocolate fireguard, and about as welcome as a fart in a spacesuit.

A bit of Googling confirmed that the problem is quite widespread. I’ve read stories of people with new phones being late for work or missing important appointments. Others describe a similar problem with other programs including not getting notified promptly of night-time messages or similar: potentially quite a problem for those "on call". Fortunately I caught the problem before it caused me any trouble, but that might not have been the case, as I have an upcoming trip with about 8 flights and several other dawn starts.

The web is full of useless "solutions" like factory resetting the phone, but after eliminating those, I tracked down the cause of the problem. With Android 6 ("Marshmallow"), Google introduced something called "Doze" mode. This is a deep sleep mode which kicks in if the device is at rest, screen off, and no significant ongoing activity like an active data transfer. You know, like it tends to be at night. In this state, the system not only slows down processing, but also suspends the bulk of normal background activity. This includes, for no articulated good reason, suspending timers and related event triggers. So your alarm application doesn’t know what time it is, and doesn’t fire. Your messaging app doesn’t know when to poll for incoming events. Simple, core functions of your smartphone just cease to work.

Allegedly, if you change the code of your alarm or other app to use a "different kind" of timer, that should work, but after testing four or five I concluded that this is just not true, certainly on my phone. In any case, I usually just use the stock Android "clock" app, and surely they would have remembered to update that, wouldn’t they? You can also nominally turn off Doze for selected applications, but as far as I can see it makes bugger all difference.

It turns out that the root problem is that in at least some Android 6 implementations, Doze mode actually disables the underlying operating system events on which the other timers are based. It doesn’t matter how sexy your alarm app is, or whether Doze knows about it or not, if the underlying timers are blocked!

There’s a heap of advice on the web about how to disable Doze for individual apps (tried that, doesn’t work), but not about how to disable it completely. I’d tried all sorts of settings without success. However I finally found a useful little app called Disable Doze, which does what it says on the tin, and turns Doze off completely. Allegedly (according to Google) this would result in my phone discharging its battery at a terrifying  rate and ending up doing a Galaxy Note 7 impersonation, but I can confirm that with Doze off in light use my phone is still only consuming about 10% battery per day. The only noticeable effect so far is that alarms and notifications work again.

My worry is that until Google acknowledge their mistakes, they may come up with another "improvement" which disables this fix. I don’t know what tests Google perform in this area, but they are clearly inadequate. This really is a "0 out of 10" effort, a true "breaking change".

However for now things are looking good, and hopefully this blog will help alert others to the problem and the fix.

Normal Service Of This Joke Will Be Resumed Shortly

When I was a lad, there was a joke. It went:

"It must have been tough in the old days."

"Why?"

"They had to watch TV by candlelight."

Last night we were just sitting down to dinner and our evening’s viewing, and the power went off, for almost two hours. In lieu of candles we lit the gas fire and an oil lamp. Not happy to abandon our entertainment, we powered up the older MacBook, popped in our X Files DVD, and got on with our watching.

That’s right – we watched TV by candlelight.

But there’s a twist. It worked, because of late-noughties technology. DVDs and a laptop with a large screen and disk player slot. If we were reliant on 2017 technology, we would have been scrod: no disc player in the newer laptops, no access to streaming services (mains powered internet router and so on), no access to the mains-powered server which holds our recorded TV.

Normal service will therefore be resumed imminently.

A catholic Taste in Films?

I’ve always wondered about the phrase "a catholic taste", meaning "broad". Surely the way in which the Catholic religion (like most others) prescribes and proscribes certain behaviours and materials acts to limit rather than broaden an individual’s tastes? Apparently the phrase derives from Catholicism being positioned as "the universal religion", and hence "a catholic taste" (with a small "c"), means "a universal taste". There may be a bit of "getting the problem out of the way in the title" going on, but that’s the official version.

However our two visits to the cinema in the last couple of days certainly challenge this interpretation. Although the two films are at opposite ends of almost any cinematic spectrum, there was an odd and unexpected common thread in our viewing which bears a bit of introspection.

On Sunday, we went to see Assassin’s Creed. This is an energetic sci-fi and action movie based on the video game of the same name. While it’s not a great film, some of the parkour "chase and fight" sequences are amazing. Apparently it was done under "Bond" rules: if they could find someone mad enough to do a stunt for real, they went for it. There are also some pretty impressive sets, backdrops and costumes. The core action takes place in Andalucía in time of the Spanish Inquisition, Columbus and the Moor withdrawal from Spain. Without giving too much away, the plot revolves around a long running war between the Catholic church, in the form of The Templars, seeking ways to suppress human free will, which they see as driving the excesses of human violence, and The Assassins, who oppose them in the name of freedom. The Templars’ position, paving the road to hell with the best of intentions, is a clever plot device, and leads to some surprisingly insightful discussions of the human condition, such as an exchange between two senior modern-day Templars debating whether they need further methods of mass control when Materialism seems to be working very well…

Yesterday, we went to see Silence. I suspect few people will see both films, and probably not very many middle-aged couples, but hey, we have "a catholic taste", don’t we? By any objective measure this is the complete opposite of Assassin’s Creed: a thoughtful historical piece rather than a game-inspired action fest, slow and considered rather than frenetic, emotional and psychological rather than active, arguably a bit too long and indulgent rather than arguably a bit curt at the end, Oscar-worthy rather than one for the Razzies. However, we then get an unexpected thematic resonance. Silence portrays the attempts of the Catholic church to introduce Christianity to Japan, and how after some initial success this was met by a brutal backlash under the the Japanese establishment’s own inquisition. While the Christians are portrayed as the heroes of the piece, they are shown as arrogant and wilfully ignorant of the Japanese religion, culture, language and institutions. While the Japanese inquisitors are shown to be brutal at times, they are also shown to be capable of subtlety, humanity, humour and leniency. By the end of the film, while you may be impressed by the strength of the Christians’ faith, you ultimately admire and have some sympathy for the Japanese establishment’s psychological as much as physical defence of its own culture. And that is basically the same plot line as Assassin’s Creed.

Neither of these films will become favourites of ours, but I’m glad we saw them both and I find the odd thematic similarities fascinating and thought provoking. In particular, both challenge the conceit of any religion which sets itself up as the "universal" moral guide. In this particular case, a "catholic taste in film" has turned out to have something of an "anti-Catholic" theme, with two films both challenging the very concept of universal catholicism. Go figure…

Mojo Not Within Normal Operational Parameters

I’m not sure I know why, but our leading hardware providers are definitely suffering a distinct deficiency in the Mojo department.

Take Apple. I’m really very happy with my 2015 MacBook Pro, even though it was bloody expensive for what it is. The limited soldered in memory is a bit frustrating at times, but otherwise it performs very well. I have never said "you know what? I would happily forgo all the connectivity if only it was a shade thinner". Instead I have started to see intermittent physical connectivity problems with the HDMI socket, which makes me extremely wary if its successor replaces the key USB sockets with smaller, flimsier ones. I can’t see the new MacBook being a good solution for me.

Maybe I’m just an old codger, but given that the device is virtually attached to my wrist about 90% of every working day I think I qualify as a "Pro" user, and I have things like "legacy" projectors plugged in a lot of the time. If I were Apple I would have two ranges of MacBooks, each in several sizes: the Air -  as light and slim as possible, with minimal connectivity or upgrade options; and the Pro, slightly thicker and heavier if needs be, but with a good selection of well engineered ports, and options to upgrade components like the RAM and SSD.

OK, let’s stop picking on Apple. What about Samsung?

Regular readers will know I was a fan of the original Galaxy Note, although it suffered with an odd memory architecture and a lack of TRIM support (which helps flash memory to be reused efficiently) and gradually got into a state where it slowed to glacial speed and couldn’t install application updates. In the meantime I had purchased the original Note 10.1", which was an excellent device apart from having to import a 32GB one from America, so I had no qualms replacing the Note with a Note 2.

That was an excellent phone, but sadly I dropped it, and it was never quite the same again.

So about two years ago I replaced the Note 2 with a Note 3, and the now ageing Note 10.1 with the 2014 edition. That’s when the rot set in.

The Note 3 was rubbish. From day one I could never keep the screen clean, and the GPS never worked reliably. It was never happy working with headphones – you had to waggle the plug to get a good contact, and even then the volume sometimes changed without warning, or the phone would go into "Hello Google" mode without warning. After not much more than a year battery life was poor, and despite always being carried in a case the top bezel stated to look quite tatty as the "chrome" paint wore off. Despite being a simple passive component, the stylus had stopped working and had to be replaced. Thanks to Samsung’s refusal to provide regular software updates It was also stuck on Android 4.4 "KitKat", with all its inexplicable limitations.

At the same time the Note 10.1 had developed a sudden reduction in battery life, rendering it unusable for long flights. I replaced it first, with a Galaxy Tab S2. That works but has its own challenges, like a 4×3 screen and speakers both on the same short edge, so not great for games or videos.

The phone was more of a problem. I really fancied another Galaxy Note as I like their unique support for a fine-pointed stylus. Unfortunately the Note 4 was apparently not much different from the 3, with the same failings in areas like GPS. The Note 5 had no SD support, a real issue given Samsung’s refusal to sell phones in the UK with decent internal storage specs. There was no Note 6.

Then came the Note 7, or #explodyphone. I’ve worked through a long career helping clients to define their non-functional requirements, and it’s not often that "I’d like it not to be on fire" crops up. Not often, but oddly enough not never either. I did help select new field devices for the National Grid gas engineers about 10 years ago, and they had fairly tough gas safety requirements, which led to us at one point having to submit a phone and OtterBox for destructive testing including setting them on fire… However, that’s pretty much an edge case, and I think we have a right to expect suppliers of normal consumer handheld devices to take that requirement as read.

You do wonder if there’s some weird competition between Apple and Samsung, and Samsung looked at the "bendy" iPhone 6, and said "you think that’s bad, just watch the professionals and learn…"

Brand loyalty being what it is, I did have one more go with Samsung, and got my hands on a Galaxy S7 Edge. Unfortunately my copy had a rare but not unknown fault where the home and back buttons trigger themselves randomly, making the device unusable. I did persevere through to the end of setup, by which time I had also concluded that the usable screen, excluding the edges, is too small for me. It went back.

In desperation I spent an hour wandering the phone shops of Liverpool, seeing a lot of the same options. Just on the verge of giving up I discovered the Sony Experia XA Ultra. This is a cheerful phone with a 6" display. It’s supposedly a notch below the Galaxies and iPhones, but I can’t see much to support that assertion. The screen size is a very good match for the Galaxy Note, battery life is fine, GPS snaps to a fix if you can see a sliver of sky, and the headphone socket just works. Predictably I have gone for the bling version in "lime gold", but there is a boring black option as well.

So far so good for the Sony, but back to my original topic, if Sony can do this with a mid-range device, why are Samsung and Apple getting it so wrong?

Taking the All-Round View

Between the Echo Arena and Jury's Inn, Liverpool
Camera: RICOH THETA S | Date: 22-11-2016 18:11 | ISO: 800 | Exp. Time: 1/30s | Aperture: 2.0 | Focal Length: 1.3mm

Apologies if it’s been a bit quiet here recently, but I’ve been submerged under a tidal wave of new (to me) technologies, and it hasn’t left much space in this bear’s brain for blogging. In the last month or so I’ve had to get my head around OpenLDAP, C#, Java development (OK, I’ve done that before, but not for about 8 years), microservices, Java Server Faces, Primefaces, and that’s just for one client. The other’s been a bit quiet, but even there I’ve had to outline and prove the concept of how to interface with an external expert systems framework.

However, that hasn’t stopped me “investing” in a few new toys. After the Cornwall trip I decided that with my changing eyesight I needed an infrared camera with an electronic viewfinder, and commissioned the guy in the USA who supplied the Panasonic GF3 to source and convert a GX7. Setting aside a nearly two-week delay through customs, mainly due to ParcelForce insisting on sending the charge note by second-class post (grr…), this turned up very promptly and works beautifully. It does appear to be a bit more fussy than the GF3 regarding whether autofocus will work in low-contrast scenes, but as I’m not likely to be using it to capture fast-moving action that’s not a major issue.

More recently, I’ve also plumped for a 360 degree camera, the Ricoh Theta S. This is a fun little gadget about the size of a small chocolate bar, with a lens on each side, and takes a 360 degree panorama in a single click of the button. It will do both video and stills, but the latter is probably more immediately interesting from my viewpoint.

There are some interesting dynamics to using this device. Firstly, it’s a return to much more of a “click and wait” process, on a shorter timescale than but otherwise not dissimilar to film photography. You can use it tethered to a phone or tablet, but a much more natural way to use it is to look for an interesting scene, hold it above your head and click, then look later at what you captured. This requires a discipline of “pre-visualisation” as Ansel Adams called it, but with the variation that you can’t just focus on what’s in front of you, but also need to be aware of what’s behind, above and below as well. A line of subjects on the horizon won’t produce a very good 360 panorama if you have an ugly or boring sky, ground or scene behind you. My usual policy of “getting high” may work fairly well, although that will produce images with much of the interest below the horizon line.

On the other hand, you do get a fascinating opportunity for what I call “post exploration”. Having downloaded the images, you can explore round them, looking at details which were invisible to you at the point of clicking, and trying to find a perspective which makes an interesting shareable static image. I’m becoming quite fascinated by the “small world” perspectives like the above, but there’s a lot of scope to go back to a favourite image and explore it again.

This process does also mean that I’ve had to join the selfie culture. At best, there are going to be a lot of shots of my thumb and the top of my bald head. However there’s a temptation to hold the camera lower and include yours truly in shot, so you have been warned 🙂

Editing is a bit tricky, as so far I haven’t found very good tools for the PC. There are reasonable tools for the tablet, which provides a fast and flexible way to view and explore the image, but the two-way export process if you want to return a cropped image (like the one above) to the PC is a bit fiddly. My search continues.

I went for the Ricoh Theta S, a slightly more expensive option, as reviews promised better image quality. It’s not bad, but like most small-sensor point and shoots there’s not much dynamic range, and so far I’m getting a lot of shots with blown highlights and muddy shadows. If there was ever a device which would benefit from in-camera HDR then this is it. There may also be some settings to explore, but given the very simple user interface I don’t hold out much hope in that direction. If I really get into this I’ll just have to find a grand for a Panono…

If you’re viewing this on a phone or tablet, have a go at exploring round the following by sliding and twisting (I haven’t worked out how to enable pinch to zoom, but I’m working on it.) Please let me know what you think.

Taking the Long View

Charlestown Harbour, Conrwall. Stitched from 6 pictures using Autopano Giga
Camera: Panasonic DMC-GX8 | Date: 25-09-2016 10:02 | Resolution: 17167 x 3410 | ISO: 400 | Exp. bias: 0 EV | Exp. Time: 1/800s | Aperture: 8.0 | Focal Length: 12.0mm | Location: Charlestown | State/Province: Charlestown, Cornwall | See map

I’m aware that I’m a slightly lazy photographer. I’m not a great one for pre-dawn starts or rushing out the minute the weather changes, and I do tend to walk around with a single zoom lens on my camera making the scene fit the lens rather than rushing to change it every shot. The other thing which can happen is I get "stuck" seeing lots of shots with a similar dynamic, rather than looking for variations.

On our recent trip to Cornwall, I kept on seeing potential panoramas, and made lots of them. A few, like this one, I’m quite pleased with, although others were middling. I took almost no 3D shots. A week later I was in Winkworth Arboretum, and I could only see potential 3D shots, almost nothing else.

This may not be a problem. There are plenty of people who focus their photography on a single subject and style, and try to become the real experts in that, like that German couple (Bernd and Hilla Becher) who just took low-contrast photos of water towers. However I do try to be more diverse, but don’t always succeed. I’m not sure what the cure is, or even whether a cure is strictly necessary. If I’m working on a more formal basis a shot list can help, but I think mainly I just need to spend more time shooting and training my eye to see the shots. Here goes…

Just Get On the Train!, Updated

Regular readers may remember that I classify films and plays according to whether they are about talking about getting on a train (i.e. deep and meaningful journeys into the soul), or actually getting on the train (/boat, /plane, /nuclear power station etc.). It should not surprise you that my own collection has rather more of the latter.

I recently updated the list, which may amuse you.
