Seeing in Black and White – Follow Up

From the Ministry of Odd Coincidences…

This evening I watched this week’s Horizon, which, by remarkable assonance with my blog, was on the topic of the perception of colour. The programme made it clear that colour perception varies widely and subject to personal and contextual forces. However, given my post this morning, I was most interested in the fact that colour perception is strongly linked to the vocabulary you have to describe colours and their differences. The Namibian tribe who have words to describe slightly different shades of green, but who lump blues and greens together under a single word, can see the former, but not a blue/green variation.

Now I’ve always had a very good physical ability to remember and match or discriminate colours, but when I first met my wife I couldn’t articulate this. To exploit my colour vision in conversations with her (such as answering “do you think this will match X?” :)) I learned a more powerful vocabulary, and in turn further developed my colour visualisation skills.

When I took up photography seriously a few years ago I became aware of the colour of light, but again really got on top if it when I learned appropriate vocabulary to describe lighting causes and effects.

So maybe my visualisation skills relate to my ability to describe (even internally) what I see or the resultant image I want. I can do this in colour because I have developed an effective colour vocabulary. I don’t “see” in monochrome because I don’t mentally describe scenes using monochrome terms, unless I’m forced to because it’s all shades of grey, or just a single colour.

The great photographers of the early twentieth century developed the vocabulary I need. Ansel Adams’ Zone System was designed for exactly this purpose, and in his writing, such as Examples he actively describes scenes using the zone terminology. I understand the theoretical concepts, but I haven’t developed the habit of using them as linguistic tools to describe a scene. Clearly I could train myself to do so, but I don’t want to lose my skill with colours as a result. The interesting challenge is whether I can become visually bilingual.

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.

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.

Review: Don’t Stand So Close

A review of "The Eagle"

As a general rule, it’s good for an action photographer to get close to said action, but I’ve recently seen a few films that demonstrate there’s a limit. One key example was “The Eagle”. It’s a stirring tale, full of great human lessons, and a great romp through Roman Britain and Celtic Scotland. I liked the visual feel, even if some of the Celtic warriors looked more African than Scots, and counter to some reviews I enjoyed the performances of both leads, as I thought Channing Tatum’s calm portrayal of the Roman an interesting contrast with the more intense performance of Jamie Bell.

The area of concern, an unfortunate one for an action film, was the fight scenes. The camera was right in with the whirring blades, and this led to two problems. The first, which several reviewers have commented upon, was that it became impossible to follow the sequence of events, or the “big picture” view of the battle’s progress. You just couldn’t work out who had done what to whom. A key Roman character is killed in the final battle, yet neither Frances nor myself could work out when, or at whose hands. This stands in contrast to, say, Ridley Scott’s direction in “Gladiator”, when you are never in doubt about what has happened.

The other problem is more personal, and I don’t know how many people it affects. My brain obviously process visual information quite quickly, and at a certain point the world’s most popular optical illusion breaks down. If, say, a sword scythes across a large cinema screen in less than a second, I see it as a series of distinct jumps as my brain discerns the movement between successive frames. While at one level I follow movement, at another I’m distracted by “spotting the jumps”. This only happens in relatively extreme circumstances, with quick movements across large screens, but it’s consistent under those circumstances.

“The Eagle” is not the only film I’ve recently seen which demonstrated these problems. This excessive closeness to the action seems to be a developing trend. directors and cinematographers need to test their work by seeing whether someone sitting towards the front of a large cinema can follow it. If not, a step back might improve things considerably.

Watching The Wall Go Up

0511 S95 0159
Camera: Canon PowerShot S95 | Date: 17-05-2011 16:59 | ISO: 800 | Exp. bias: 0 EV | Exp. Time: 1/25s | Aperture: 4.9 | Focal Length: 22.5mm | Lens: Canon EF-S 10-22mm f/3.5-4.5 USM

Thanks to some generous colleagues and the last minute availability of a spare “hospitality” ticket, I was lucky enough to get into a sold-out Roger Waters concert based on Pink Floyd’s The Wall this week. It was a really great show, and prompts several different observations.

First: the concert itself. I can only think of superlatives to describe it. Essentially while the music played and described Pink’s increasing isolation, the Wall of the metaphor was progressively built up, in front of the main part of the stage. The Wall was then used as a screen on which a variety of projections were shown: some simple graphics, many derived from the original Gerald Scarfe illustrations for the album, and others illustrating some of the social and political philosophies behind the lyrics. The projection technology was amazingly sophisticated, being able to extend to individual bricks as they were inserted, so that there was no “spill” onto the background activities which had their own lighting and pyrotechnics.

The music and sound quality were simply superb. I have been to concerts at the O2 where the sound was a bit muddy, but that wasn’t a problem here: every note and word as clear as on the album, albeit with the variations which you’d expect in a live performance, by a slightly different group of musicians, 35 years on from the original.

This is also a “photography” post for two reasons. Firstly, it was refreshing and encouraging to attend a concert with a realistic, liberal attitude to photography, which was clearly presented in both notices and an announcement: attendees were welcome to take photos, but would they please ensure their cameras were set to “no flash”. It was slightly disappointing to see that a few audience members couldn’t follow this simple instruction, but overall it worked well.

I had taken my tiny Canon PowerShot S95 in my pocket, and I’m very pleased with the results. The above was taken from the back of the hall, at ISO 800, on a camera about the size of a cigarette packet. This isn’t the limit of the camera’s capability: I got some decent shots at ISO 1600, albeit applying quite aggressive noise reduction in my RAW processor, and the in-body image stabilisation seems to have worked down to about 1/8s. OK, my photos are not going to blow up to A2 or sell as fine art prints, but as memories of a great concert obtained without carrying my normal (and probably forbidden) heavyweight kit they are very encouraging.

Finally, I must confess a slightly ambivalent attitude regarding “corporate hospitality”. I wouldn’t have got to the concert if it was not for some generous colleagues at Accenture, and I’m extremely grateful to them for that generosity. But while the Accenture box was full, the next box along was empty, as were several others, with seats at a very popular event going completely wasted. As someone who only normally attends such events via “general admission”, this is enormously frustrating. I don’t know that there’s any real resolution, but it’s something event organisers really need to think about.

Spring is Here!

A montage in the style of Eadweard Muybridge, developed at a dance masterclass with Chris Nash
Camera: Canon EOS 7D | Lens: EF-S15-85mm f/3.5-5.6 IS USM | Date: 07-05-2011 15:34 | Resolution: 5184 x 3456 | ISO: 100 | Exp. bias: 0 EV | Exp. Time: 1/125s | Aperture: 8.0 | Focal Length: 28.0mm (~45.4mm) | Lens: Canon EF-S 15-85mm f3.5-5.6 IS USM

One of my birthday presents was a dance photography masterclass, hosted at the Victoria and Albert museum and led by renowned dance photographer Chris Nash. This was a bit of a departure for my photography, although followers of my blog may remember I captured a couple of satisfactory shots from late night entertainment on my Cuba trip.

The above is a montage of three shots taken trying to capture Soledad doing an impressive flying leap. It’s my homage to the work of Eadweard Muybridge. I think it works, although it has reminded me why I try and develop my images directly in the RAW processor, with as little messing around in PhotoShop as I can manage.

Thanks to the V&A for hosting an excellent event, to Chris and his team for leading a very inspiring and educational course, and to Soledad and her companions for working very hard, tirelessly and without complaint, and presenting us with some wonderful movements and shapes to work with.

Compact Camera Alienation?

Are compact and cellphone cameras fundamentally unsuited to a significant subset of the population?

I am short sighted. With an SLR I look through the viewfinder at an image focused at the optical equivalent of about 1m, maybe a bit less with “diopter adjustment” applied, so I can view it fairly easily regardless of whether I need my glasses for the scene or not. With a compact camera I hold it at my natural reading distance of about 40cm (a bit less than 18″), which is both optically comfortable and a good distance at which to hold and operate the camera. The same will be true for those with normal sight.

This is not true for those who are long sighted, which includes a majority of those in middle age or older. These people will be comfortable looking at longer-range subjects without glasses, but will need them for shorter-range subjects.

The SLR, or even an “electronic viewfinder” camera with diopter adjustment, should be fine. As long as the effective optical distance of the focusing screen is 1m or more it should be viewable with glasses off if that’s correct for the target scene, and because it’s viewed inside a dark “tunnel” the effective distance is not an issue.

But a compact camera can be a real challenge. The user has to either hold it inside their comfortable viewing distance, and accept a blurred image and other display data, or hold it so far away that both camera shake and incident light become issues, or try switching between glasses to view the camera and none for the scene itself. None of these is a good option. The result is a camera which is effectively unusable by that person.

I saw this in action myself yesterday. I was sitting in a restaurant with Frances, and she had a good view of a potential photo, but I didn’t. Thinking it would be easiest, I handed her my little Canon Powershot S95. Useless. Eventually I rummaged under the table for the “big lump” (Canon 7D and 15-85 lens, all 1.6kg of it ;)). No problem.

I do wonder if the move to fewer and fewer small cameras having optical viewfinders is a wise one, or if it will alienate a significant proportion of potential photographers.

What to Get for a Photographer’s Birthday

0311 7D 4518
Camera: Canon EOS 7D | Lens: EF-S15-85mm f/3.5-5.6 IS USM | Date: 13-03-2011 10:43 | ISO: 400 | Exp. bias: 2/3 EV | Exp. Time: 1/10s | Aperture: 8.0 | Focal Length: 29.0mm (~47.0mm) | Lens: Canon EF-S 15-85mm f3.5-5.6 IS USM

With my half century finally upon me, my wife Frances has excelled herself by commissioning a most wonderful cake, celebrating my photographic passion! This is well up to the standard of “Bear in a Porsche“, from a few years back…

Those of you who have known me for some years will recognise that “Tatty Bear” probably more accurately reflects my shape and condition than my earlier icon, the “Forever Friends Bear”. Ah well, that’s the advancing years for you.

Of course, some of you will also know that it’s a long time since I last shot a roll of film, but somehow I think a row of 1s and 0s around the base of the cake wouldn’t work nearly so well. And I did manage to help expose four sheets of 8×10 on my last visit to Barbados, so I can’t claim to be absolutely 100% digital 🙂

Quick plug: if you need a good cake maker, then the above creation was the work of Jonathan at Simply Cakes in Weybridge. Having now sampled it, I can confirm it tastes just as good as it looks, so I’m happy to recommend him.

Don’t Pose, Please, Just Act Natural

Iguana at the Barbados Wildlife Park
Camera: Canon EOS 40D | Lens: EF70-300mm f/4-5.6 IS USM | Date: 20-04-2010 20:36 | ISO: 200 | Exp. bias: -1/3 EV | Exp. Time: 1/125s | Aperture: 5.6 | Focal Length: 300.0mm (~486.5mm) | Lens: Canon EF 70-300mm f/4-5.6 IS USM

Those who follow my photography blog will know that my preferred technique for taking portraits is to use my 70-300mm lens towards the long end of the zoom range. It only works as long as the subject is effectively frozen by the available shutter speed, but for a static subject that can be as low as about 1/20s, relying on a combined steady head and image stabilisation technology to keep things sharp.

This technique works for pretty girls, character-full old men, and, as this shows, for those who might not take direction even if you wanted to provide it!

So if you see an interesting face, but it’s some way off, hold the camera steady and go for it. The results may be better than you expected.
