Seeing in Black and White

Garden at Sissinghurst Castle, Kent
Camera: Canon EOS 550D | Lens: EF-S17-85mm f/4-5.6 IS USM | Date: 07-08-2011 14:11 | ISO: 200 | Exp. bias: 0 EV | Exp. Time: 1/50s | Aperture: 8.0 | Focal Length: 22.0mm (~35.6mm) | Location: Rolvenden Rail Station | State/Province: England | See map | Lens: Canon EF-S 17-85mm f4-5.6 IS USM

Some experienced photographers, particularly those with a background in traditional film photography, claim to be able to “see” a scene in black and white, visualising how a monochrome version might work. This focuses on the tonality, and ignores the colours in the scene.

I’ve been trying to do this, with a little success, and I’m quite pleased with this scene I captured at Sissinghurst last weekend, where I managed to visualise in advance the effect of the statue against the hedge, and the shadow on the lawn.

But I’ve realised I can only do this where the scene is dominated by a single colour. In this case, it was all different shades and tones of green (or grey). As regular readers and friends will know, colour is very important to me, and when the colour palette is richer, I find it very difficult to ignore my interest in the colours and focus only on the tones.

I wonder whether the best black and white photographers are just less interested in colour in normal life, or whether they can switch their vision of the colour on and off, something I can’t do?

The Challenge of Serenity

In the Chapel of Onzelievevrouw (Our Beloved Lady) Basilica in Maastricht
Camera: Canon EOS 7D | Lens: EF-S15-85mm f/3.5-5.6 IS USM | Date: 22-07-2011 17:16 | Resolution: 5160 x 3434 | ISO: 1600 | Exp. Time: 1/19s | Aperture: 5.59 | Focal Length: 17.0mm (~27.5mm) | Location: Mercure Maastricht Airport 3 | State/Province: Limburg | See map | Lens: Canon EF-S 15-85mm f3.5-5.6 IS USM

Our Summer city break this year was a short trip to Maastricht in Holland. No, I didn’t have a treaty to sign, but it’s still a charming old European town, with great architecture and great shopping. The high point was the last live music event of our Summer, a concert fronted by the Dutch violinist Andre Rieu. We didn’t know quite what to expect, vaguely thinking about violin solos. What they actually provide is a bit like a Dutch “Last Night of the Proms”, performed outdoors, with musical inputs ranging from a South African gospel choir to the current Three Tenors. Andre Rieu is just a great showman (I could follow much of what he was saying even though I don’t speak Dutch), and seems to treat his beloved Stradivarius a bit like other “front men” treat their tambourine or harmonicas – mainly something to keep the hands busy!

Talking about things beloved, the photo is from the Chapel of Onzelievevrouw (Our Beloved Lady) Basilica. The chapel is an “island of serenity” in a bustling town, and many of the visitors stop to pause here. Apparently they get through roughly 1000 candles a day…

I really wanted to capture this photographically, but the challenges are substantial. Firstly, the dynamic range demands HDR. Even allowing the candle flames themselves to blow out the range must be 14 stops from the candle bodies to the shadows, and I didn’t just want a white stripe across a black background 🙂 Flash would be completely unacceptable killing both the beautiful reflective mood, and also the very subtle lighting I was trying to capture. Using HDR gets to the next problem: movement. Not only are people coming and going all the time, but of course the camera flames themselves are moving. It wouldn’t be acceptable to use a tripod, and I didn’t have mine anyway. All these place a lower limit on the shutter speed, and require a fairly high “working speed” to capture the few moments when the other people are motionless.

This wouldn’t matter in a typical outdoor situation or even a well lit interior, but away from the candle tips the light levels in the Chapel are very low. At ISO 1600 I was looking at f/5.6 and 1/20s for the “nominal” exposure. That’s more or less the limit of my lens, and I wouldn’t want a much wider aperture for this scene in any case. This in turn implied a challenging 1/5s shutter speed for the “+2” shot. I didn’t want to crank up the ISO any further, as the noise would be unworkable in an HDR image.

Several attempts later, this was the best result. This Japanese couple paused just long enough to give me a nice composition without human movement. For some reason I can’t get a high-quality result using all three frames – I must have moved the camera between frames slightly more than the software’s limits – but the nominal and “-2” exposure combined well in Photomatix Pro using the exposure fusion method. Although there’s not quite as much shadow detail as I hoped for I think it works, but it also illustrates the limits of current digital photography.

Not from My Cold, Dead Hand…

My regular correspondent Malachy Martin recently posed another of his “research” questions:

What would work look like if you only had an iPad as your computing device?

My first reactions focused on whether my iPad could replace my laptop. Then I had a horrible second thought:

“I hope he doesn’t mean taking away my phone!”

I suppose I could go back to carrying a separate phone (or bag of 20p pieces), diary, address book, alarm clock, notepad, dictaphone, GPS, map, camera (well, I do do that, but that’s different), puzzle book, music player…

Yes, the iPad can do all of these, but it’s just too big to carry around all the time. I’m certainly not going to strap it to my arm in the gym, or hold it to my ear in public. So let’s assume I’m allowed to keep my phone, and focus on my first interpretation of the question. Could the iPad replace my laptop? What couldn’t I do without the latter?

First, say goodbye to a lot of content creation. The iPad touch keyboard is just too slow and inaccurate for entering large amounts of text. The ZaggMate keyboard which comes combined with a cover for the iPad screen is great, and at least allows you to navigate and select text accurately, but it suffers from some nasty key bounce and the keys are a bit too small for my fingers. Even ignoring physical text entry problems, you’ve got the challenge that there’s no truly compatible version of MS Office for the iPad, so creating properly compatible structured Office documents is almost impossible.

The problem is even worse in respect of graphical content. Set aside the fact that I do a lot of image processing on my laptop, which requires both substantial horsepower and a proper PC-level operating system. The iPad just doesn’t hack it for fine graphical manipulation. I can reliably drive a PC with a mouse to an accuracy of 1-2 pixels (in 1280 on my laptop, and 1600 on my desktop). The iPad is designed for operation with a 1/2″ paintbrush, and is realistically limited to operations suited to such a tool.

I do a lot of development work, with 2 full scale databases, 2 web servers, various modelling tools, a Java development environment and no fewer than 6 versions of Visual Studio on my laptop, plus a couple of virtualised alternative PC operating systems. That’s not going to work on my iPad! I could cheat and move to “thin client” (Remote Desktop) access to the equivalent running on a server somewhere, but that would function only when I’m connected (I’m often not when I want to do such work), and the navigation and text entry limitations of the iPad would drive me bonkers.

Even for general “office” work the limitations of iOS would rapidly challenge my sanity and productivity. For example, when I’m developing complex documents I do a lot of multi-tasking, working across multiple open documents each of which needs to be in a fixed known state under my control. I also make a lot of use of drag & drop and working with multiple windows visible at once.

The other big problem is iOS’ lack of content management separate from the “apps”. I manage about 200GB of “content” on my laptop: client files, my own documents, photos, technical library, publications etc. This is all synchronized to the big desktop/server at home, but available offline. The thought of all of this being tangled up with individual applications is just horrific.

So no thank you Malachy, the iPad isn’t going to replace the laptop or the phone any time soon. Now if someone can come up with a Windows 7/8 slate with the same performance and capacity as my laptop, and the same battery life as my iPad, and capable of operation with either a finger or a stylus…

Turning Points

A regular correspondent of mine just posed an interesting question: “The Web has significantly evolved over the past 15 years. What have been the major milestones in the web’s evolution either in business or technology?”

 

That’s quite a big question… 🙂  I didn’t have time for a detailed answer, but came up with the following main “turning points”:

  • 1996-7: The “ubiquitous web” becomes useful. This was the point at which someone with an average PC and dial-up connection could perform real tasks as well as or better than going to a traditional intermediary, e.g. for booking holidays.
  • c2003: Composite applications and services start to become a reality (e.g. Amazon marketplaces). This required a number of technological advances (RSS, web services), but also a shift from human-computer to computer-computer interactions. I was never completely convinced about “web 2.0”, but in hindsight I suppose this was what it meant.
  • c2005: The web becomes “the main way of doing things” for things like banking, tax & interactions with the government. Before that date I was often frustrated either by not being able to use the web, or frustrated because of the services’ limitations. Since that sort of date I’ve only had to perform a handful of such transactions by other means, and they’ve usually been a disaster!
  • c2009-10: The web starts to deliver on the mobile “information everywhere” vision, as per things like Bill Gates’ The Road Ahead. It’s the confluence of decent large-screen hardware, standards-based services and well-designed apps. Put it another way – this was the point at which the computing in Star Trek, the Next Generation started to look out of date, just as the original series did by 1987.

I’m aware that this is very focused on practical, e-commerce type uses. I’m not personally convinced that social networking represents a watershed in itself, rather than another exploitation dimension, which probably has a very similar set of milestones. The same is probably true of several other content / application areas.

What do you think? Have I nailed it, or have I missed a big one?

…And Then Three Come Along All At Once

Jon Lord and Rick Wakeman perform "It's not as big as it was" at Superjam 2011
Camera: Canon PowerShot S95 | Date: 08-07-2011 23:03 | ISO: 800 | Exp. bias: -2 EV | Exp. Time: 1/40s | Aperture: 4.9 | Focal Length: 22.5mm | Location: Upper Rissington | State/Province: England | See map | Lens: Canon EF-S 10-22mm f/3.5-4.5 USM

Reflections on an excellent Summer for live music

I understand why buses come in threes. If you’re interested, it’s simply because the one at the front does most of the picking up and setting down, and the others just catch up. However, I don’t understand why live music appears to work the same way.

We normally manage at least a couple of “big” concerts each year, but we didn’t find much to inspire us in the whole of 2010. Then suddenly the famine turned to feast, and between the beginning of March and the end of July I’ll have managed a total of nine live music events! These have really covered the range: from reggae to rock, from a tiny dinner jazz gathering with two musicians to the extravagant production of Roger Waters The Wall, and from classic rock acts to classical violin.

By very weird coincidence having never seen any of the classic American rock bands apart from Chicago, we then added four more scalps in three weeks. Journey, Foreigner and Styx (see this post) were followed in short order by Toto, at the much better venue of the Hammersmith Apollo. This was an excellent concert, and the youngsters now fronting up Journey would do well to go and view the older masters at work. All the great hits, good interaction with the audience and each other, and a decent sound mix. That’s how it should be done.

However, the best of the lot, heading rapidly for a place in my all time top ten, was also one of the oddest. Superjam 2011 at the Royal Albert Hall last week was a charity concert in aid of Great Ormond Street Children’s Hospital. The organiser is one Jackie Paice, wife of Ian, so naturally the music revolved around Deep Purple and their friends. And what a bunch of reprobates turned up…

After a lengthy charity auction (where those of us in the cheap seats got to have a distant look at the sort of people who can splash out 20 grand in a good cause) the music got going at about 9.30. The first act set the tone for the evening, with Newton Faulkener doing a version of Bohemian Rhapsody, complete with the complicated bits, as a solo with just an acoustic guitar. Various guests followed, each doing their own party piece, typically a tribute to another great musician, alongside one of their own works. Joe Bonamassa did a great version of BB King’s The Thrill is Gone, and Gary Brooker turned up with Good Golly Miss Molly, followed, of course by Whiter Shade of Pale, which I certainly never expected to hear live by the original singer.

At this point there were still two Hammond organs and a big bank of synthesisers sitting unused on the stage, but that was about to be rectified. First by Jon Lord, who after a rocky first number then produced a spine-tingling version of Sarabande, with the both talented and attractive young violinist Anna Phoebe, and then an ethereal version of his ballad Pictured Within. Jon handed over to Rick Wakeman, who amused us with variations on Eleanor Rigby in the style of Prokofiev, as only he can, and then brought Jon Lord back on for a duet for Hammond organ and synths. This work, composed for the concert, was humorously about two old men comparing their “organs”, with the wonderful title It’s Not As Big As It Was :). Finally everyone came back on stage for the first half finale, Life On Mars, which Rick Wakeman apparently co-wrote with David Bowie.

After a short break, the second half started with Bill Bailey doing a very funny, but very odd, act with a six-neck guitar (!), followed by an even odder, even funnier medley of rock anthems in the style of Chas and Dave. At last Deep Purple took the stage, and belted through several of their classics. They were characteristically generous to the younger musicians, including Joe Bonamassa coming on guest guitarist on Maybe I’m A Leo.

But they left the best till last. The finale was Deep Purple doing Smoke On The Water – “nothing new there” I hear you say, but wait … – with Bill Bailey out front playing the infamous riff – on a set of cow bells! Musically spot on, and very possibly the funniest live music performance I have every seen. 😀

Maybe this wasn’t the most polished set of performances ever, and maybe the sound quality up in the back row of “the gods” wasn’t the greatest, but who cares? The music was stirring, the evident friendships and goodwill heartwarming, and I laughed like a drain. If there’s a better way to raise some money for a good cause I’m not sure I’ve experienced it.

What’s in a Name?

I just had a bit of a scare. An app which tracks my Twitter activity informed me that “DignitasLtd” had started following me. Of course, I immediately thought of the Swiss clinic, and wondered what they knew that my doctor wasn’t telling me…

A little research later, and it transpires that @DignitasLtd is the Twitter handle of a software consultancy in the West Midlands. I haven’t confirmed it yet, but I suspect it may be someone I work with, or have worked with, at National Grid.

Panic over, but I wonder who else has this problem. Is there an @BadLuckAndTrouble or an @DeathAndDestruction out there?

Image Stabilisation – Know Your Limits?

Ceiling detail from the Teatro Tomas Terry, Cienfuegos, Cuba
Camera: Canon EOS 7D | Lens: EF70-300mm f/4-5.6 IS USM | Date: 20-11-2010 17:48 | ISO: 800 | Exp. bias: -2/3 EV | Exp. Time: 1/13s | Aperture: 5.0 | Focal Length: 140.0mm (~226.8mm) | Lens: Canon EF 70-300mm f/4-5.6 IS USM

I’ve blogged previously on the other merits of Canon’s wonderful EF 70-300mm f/4-5.6 IS USM lens, but not really its image stabilisation characteristics. This shot from Cuba shows how good the lens is in that respect. The above is an interior detail from the Teatro Tomas Terry in Cuba, shot handheld in very low available light, at 140mm and with a 1/13s shutter speed. I’m very happy with its sharpness. Some of this may be down to my own steadiness, but it does seem that I can genuinely go to speeds 10 times slower than the traditional “1 over the focal length” rule. I’d be interested to hear what other people have found with similar lenses.

Low Cost Geotagging Using Bibble

I decided a while ago that it would be useful to “geotag” my photographs, i.e. to automatically record the location from which each is taken and add that to each images’s metadata. As my next photographic trip is to Iceland and I rate my chance of correctly remembering and spelling all the Icelandic names as about 0%, this could be very useful.

I looked at commercial solutions, but they have several drawbacks, including the need to carry at least one more gadget, and some questions about how they would fit with my photographic workflow. Then I realised that I could achieve a similar result using just my new mobile phone and some low-cost software which can integrate neatly with my Bibble-based workflow. Read how my solution works in this article.

Journey, Foreigner and Styx

Foreigner at Wembley, 4th June 2011
Camera: Canon PowerShot S95 | Date: 04-06-2011 20:26 | ISO: 1000 | Exp. bias: -2/3 EV | Exp. Time: 1/20s | Aperture: 4.9 | Focal Length: 22.5mm | Location: Wembley Arena | State/Province: England | See map | Lens: Canon EF-S 10-22mm f/3.5-4.5 USM

A few weeks ago I attended a concert bringing together three classic American rock bands: Journey, Foreigner and Styx. It was not a bad evening’s entertainment, but left me with mixed feelings and musing on what makes for great live music.

The venue was Wembley Arena. It’s not our favourite venue by a long chalk. The main problem is that it’s long and thin and most of the audience are facing at right angles to a proper view of the stage. It also seems to suffer much worse than other venues from “fidgety audience syndrome” – I’m not sure whether this is related to the layout or not. What I do know is that watching a concert at Wembley is a constant battle with people coming and going to the bars and WCs, with no vestige of consideration for those actually trying to enjoy the show. This time people in the row behind us chose the middle of “Cold as Ice” to have an argument about tickets – surely they could have enjoyed the number from the side and then sorted things out?

I hadn’t really appreciated the relative ranking of the bands, so was a bit surprised when Styx led off the show, very much as the junior band working on a thin strip at the front of the stage. Another surprise was the musical style, prog rock rather like an American Yes, whereas I went in thinking of the ballads like “Babe” and Dirk DeYoung’s solo work. Even if it wasn’t quite what I expected, the performances were solid and varied enough to hold our interest. While musically I had no complaints, I was really annoyed by a bright light shining straight into my face from head level on the left of the stage, which made photography or even concentrating on the performance a real challenge.

Foreigner were simply superb. They played all their hits, the sound quality was good, the lead singer interacted well with the audience, and we even had a sing-along to “Feels Like the First Time”. The lighting effects were excellent and the band moved around using the stage and each other very effectively. Plus that stupid bloody light had been reset sensibly! This was more like it, and I was sad their set only lasted about an hour.

After Foreigner there was a big gap, well over half an hour, as the stage was completely stripped and re-set for Journey, behaving very much as the headline act courtesy of the renewed success of “Don’t Stop Believing”. When the show finally restarted the opening was very promising, with a thundering number and the voice of the energetic young vocalist soaring overhead.

The trouble is, that was it. 3/4 of an hour in I was getting tired of thundering numbers with high pitched vocals. I can’t tell you what they played, because I couldn’t distinguish one song from another. Normally even if I’m not familiar with a band’s catalogue, I could describe “the acapella one” or “the one with the great drum solo”. Nope.

There’s a musical joke on Deep Purple’s “Made in Japan”, where Ian Gillan asks the sound man for “a bit more monitor if you’ve got it”, and behind him Glover or Blackmore shouts “yeah, we’d like everything louder than everything else!” The trouble is that Journey and their sound team didn’t understand this was a joke…

Add to that virtually no interaction with the audience, and the lighting guy now shining the whole bank of lights in our eyes at regular intervals, and Journey just didn’t work. We gave up and left before the end of the show.

As a seasoned concert attendee, I’ve long realised that the success of a band has very little to do with the excellence of their live performances. It’s just frustrating to see the headline act do something so badly, when the acts further down the bill are so good.

Back to Cuba!

Nice old green car under dappled light on the Malecon in Havanna, Cuba
Camera: Canon EOS 7D | Lens: EF-S15-85mm f/3.5-5.6 IS USM | Date: 15-11-2010 16:00 | ISO: 200 | Exp. bias: 0 EV | Exp. Time: 1/250s | Aperture: 3.5 | Focal Length: 15.0mm (~24.3mm) | Lens: Canon EF-S 15-85mm f3.5-5.6 IS USM

Not literally, unfortunately, but I’m finally getting on top of my shots from last November’s trip, and I thought I’d share some of them with you. Here’s one I rather liked of a green car under dappled light on the Malecon, the broad street and walkway which runs through central Havanna.

iPad Communications Errors

I don’t know whether any other iPad / iPhone users out there get the same problem, but I’d be interested to hear if you do.

Quite often I go to use an app which needs to communicate over the Internet, and it gets “stuck”, clearly trying to communicate but with nothing happening. Depending on the app it may just sit there forever, or the operation may time out with an error. The iPad as a whole is still responsive, I can switch apps and use those which don’t need comms, but at that point all comms from all apps appear to be blocked. The only solution I have found is to switch the iPad off and on again.

This is now sometimes happening several times a day. I thought Apple products were supposed to be so reliable they never needed a reboot? This is worse than a twenty year old Windows PC.

The problem seems to have got worse since I started using Twitter, and installed a couple of apps which wake up periodically to check for new activity. It therefore seems like there may be some common comms routine or resource which is essentially single-threaded and can get into a deadlocked state if there is more than one call on it.

Does anyone else suffer this, or know how to fix it?
