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 "Found" Quadtych

Four supporting gargoyles at the Thimpu Dzhong, Bhutan
Camera: Panasonic DMC-GX7 | Date: 15-11-2015 14:54 | Resolution: 13696 x 3265 | ISO: 1600 | Exp. bias: 0 EV | Exp. Time: 1/200s | Aperture: 7.1 | Focal Length: 103.0mm | Location: Tashichhoe Dzong | State/Province: Thimpu | See map | Lens: LUMIX G VARIO PZ 45-175/F4.0-5.6

The blog has been looking a bit light on pictures recently. Meanwhile I’m beavering away trying to finish tidying up the Bhutan pics before I’m off to Burma in February. This morning I discovered a series of four similar close-ups on supporting "gargoyles" (I suspect that’s not quite the right term in the Bhutanese context, but close enough) which I never originally envisaged as a multi-shot combination, but which I think actually work quite well as a "quadtych" (which is exactly the right term, apparently).

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?

A Splash of Colour

Detail from the Tiger's Nest Resort, Paro

No deep philosophical observations today, but with the weather swinging between cold and misty, and mild and murky, I thought it would be nice to brighten things up a bit. I’m working through the remaining shots from Bhutan, before another planned trip in the New Year, and this shot from our arrival on the first day cheered me up a bit. I hope it also works for you.

Night-Time Photography with the Sony RX100 Mk IV

The Pump House and End of Albert Dock, Liverpool
Camera: SONY DSC-RX100M4 | Date: 29-11-2016 20:20 | Resolution: 5718 x 3574 | ISO: 250 | Exp. bias: -0.7 EV | Exp. Time: 1/30s | Aperture: 1.8 | Focal Length: 8.8mm (~24.0mm)

Last night was crisp, clear, cold and very still – theoretically ideal conditions for photographing the lights at Albert Dock with reflections in the water. I couldn’t get out any earlier, but did manage to take my Sony RX100 with me on the way to a dinner meeting.

Unfortunately I was well past "blue hour" so there was no light whatsoever in the sky or its reflection. This presented a bit of a problem, in that it’s a real challenge to a camera’s dynamic range, and the tendency is to over-expose the highlights (lights). The RX100 also insisted in the longer views in defaulting to ISO 6400 (because of the low overall light levels), and in the cold I didn’t have the patience to fix this properly.

The result is that the best shots were those with a reasonable level of foreground light, like the one above. The image quality is excellent, as is the control of the highlights, especially considering it was taken on a small sensor camera in what would be low light by most standards. However I did have success with a couple of longer shots, typically where there was an illuminated building to lift the overall luminosity. The one below is a decent example.

The moral of the tale – try and get out a bit earlier, and set the auto-ISO limit a bit lower!

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.
