Venice by night

off the beaten track

in Photography , Monday, March 18, 2013

Of all the photos I took over my recent 3 day trip to Venice, this is my favourite, and the one I chose to print.  It’s also the first large (A3+ for now, but I’m going to make an A2 for framing) print I’ve made from a Sigma DP2M file, and the detail is just shockingly good. It’s difficult to settle for less now!

Ok, so it’s not the classic Venice shot by any stretch, but it’s the sort of atmosphere I was looking for. More Michael Dibdin than Agatha Christie.

I was also pleased to find that you can make long exposure photos with the Sigma with no particular problem. The auto white balance is pretty weird, but that is fairly easily fixed.

Sigma in Antarctica

good in parts

in Antarctica , Tuesday, February 05, 2013

As I confessed a little while back, I failed to resist the temptation to buy yet another camera. But the Sigma DP2 Merrill seemed irresistible, especially given that its cantankerous and awkward nature dovetails so closely with mine. I managed to convince myself that, potentially, it could be a fantastic tool to use in Antarctica. So, here are some thoughts on how it worked out.

First of all, it would have been a lot easier if some low-life scumbag had not stolen my shoulder bag in Buenos Aires, which at the time contained my 3 spare batteries for the Sigma, and its lens cap. And a few other things, but of no value whatsoever to the aforementioned scumbag (note, this is just part of life in Buenos Aires. Thievery is rampant. But 99.99% of the people are great).

This setback led to me using the Sigma a lot less, since one battery gives, at best, 70 shots. Had I used it more, I might have got more familiar with it, which might have altered my experience with in in Antarctica. But I’m not sure of that.

My DP2M is equipped with an optical viewfinder, lens hood and JM combo grip. All three were very useful.

The DP2M is actually quite well designed. The menu system is clear and well laid out, and the various buttons are fairly obvious. In calm conditions, with plenty of time to think, it’s fine. However, in a Zodiac, in snow, wind and rain, it is a bit of a handful. The main problem lies with focussing and composing, which is a bit crucial, really. To focus, you need to use the rear screen, and unfortunately, in most conditions I find it quite hard to do this without reading glasses. I’m not getting any younger. You can of course get a focus confirm light close enough to see when looking through the optical viewfinder, but that doesn’t tell you what you’re focussing on. One way to work was to take a quick glance at the screen first to see where the chosen focus was looking, roughly, then compose through the viewfinder. This worked ok sometimes, obviously better for distant subjects. Another method is to use manual focus, but that requires glasses to work well. Or to use autofocus on a blurry object on the screen, matching this up with what I could actually see in front of me. All in all it’s a miracle that anything was in focus.

Another associated problem involves the shutter button. It is far to sensitive, especially for the focus and recompose, or focus-on-point-that-penguin-is-heading-for method. The difference between a half press and a full press is marginal, and the lightest pressure will trigger the shutter. This is even trickier when wearing gloves.

Finally, one has to pay careful attention when moving the focus point around in case by mistake you’re altering the exposure compensation. Or vice-versa. Oh, and the focus mode button can trip you up to, especially if you accidentally leave it in “limiter” mode, and then try to work out why you can’t focus on anything close.

All of these issues don’t really arise on a pleasant sunny day when you have all the time in the world, but photography from a moving platform in cold, damp and windy conditions is another matter altogether.

So what about the results ? Well, one thing I might have discovered if I’d used it more is that the DP2M underexposes drastically in snowy conditions, by around and sometimes over 2 stops. The histogram on the back of the camera is near-useless, so it isn’t until getting into post-processing that this becomes really noticeable. And I didn’t have much time to dive into Sigma Photo Pro onboard ship. Speaking of post-processing, I was pleased to find that Iridient Developer 2.0 was released while I was away, and it supports the Sigma Merrill files. However, having run a whole series through it, I discovered it has some serious issues dealing with less than perfectly exposed files.  Most of my Antarctic shots feature grey skies, and in the Iridient interpretations of these there is often drastic variation of colour balance across the width, with nasty green tinging on both edges. This was … disappointing. However, Sigma Photo Pro actually works some magic which removes this effect pretty much altogether.  Iridient is much easier to use, and more sophisticated, and I love its split toning sliders, but for now with these images the only solution is SPP + Photoshop.

In conclusion, I’m tempted to say that it really wasn’t a very successful experiment. However, there was a degree of operator inexperience involved, and the totally abysmal weather didn’t help either. Probably I wasn’t committed enough either, as I had two other cameras with me! Half of me feels like strongly advising against using this camera in such conditions, but the other half feels that there was a lot of lost opportunity.

Here’s a few initial stabs at processed photos. Maybe it wasn’t a complete disaster…

Stress Testing: gear in Antarctica

next up, “which anorak”

in GAS , Tuesday, January 29, 2013

Time for some gear talk. As I’ve mentioned before, I have an insane amount of stuff with me here, and it’s getting to be a real drag. But here are a few notes about some particular items, which might be of use to other travellers.

ThinkTank Airport Commuter backpack

Before travelling I was getting somewhat paranoid about carry-on baggage, in particular my photo backpack. Although I have taken every backpack I’ve ever owned on flights with no problem, including my current LowePro ProTrekker 400, an excellent hiking pack, I was still concerned about the weight of the bags themselves, and especially Aerolineas Argentinas’ reputation for stinginess. So based on reviews on Roël’s web site, and on the experience of two of my companions on my Svalbard trip a few years back, I bought a ThinkTank Airport Commuter. In terms of carry-on size, it worked fine. It also swallowed an impressive amount of gear, and although the padding is light compared to LowePro standards it proved to be quite adequate. However, it has one huge, huge problem: the rather pointlessly removable waist belt strap managed at some point to remove itself in transit, leaving me with a very uncomfortable pack. Some time later one of the equally detachable tripod straps decided to go solo. This turned a comfortable bag into a nightmare. Otherwise the bag is ok, rugged enough for day hiking and fairly impermeable to penguin guano. It has good laptop and iPad pockets, but nothing like the range of thoughtful accessory pockets that LowePro include. It is remarkably light and well constructed, but the detachable strap issue is a major problem. For this reason I would not personally recommend it, and would be very wary of buying another ThinkTank product. Oh, and either things have changed a lot, or Aerolineas Argentinas has a very unjustified reputation. In my experience they are very tolerant on both cabin and hold baggage allowances, and in general are a great airline.

Sigma DP2 Merrill

One excuse for buying the Sigma was Antarctic landscape photography. Well, it didn’t really work out. In the field, composing on the LCD is not my idea of fun, even though the screen is quite good. The shutter button is much too sensitive for focus and (re)compose work, especially when wearing gloves, and the controls are in general fiddly. Manual focus is basically impossible in anything but the most tranquil conditions. The optical viewfinder works ok, providing you have a rough idea where the focus point is, or you’re shooting far-field only. So far I haven’t really gone through many files, so I can’t say much about image quality, but from quick LCD reviews the colour seems a bit weird. We shall see. But generally I didn’t get much benefit from this camera in Antarctic conditions. Possibly an SD1 would have worked out better - but again with a lot of limitations.

Acratech Swift Clamp

I started using a Black Rapid strap a few months before travelling to Antarctica, and in general I like it, even if the carabinier managed to unlock itself a few times. But the problem with this strap design in general is that it uses the tripod socket. Acratech offers to solve this problem with their quick release Arca Swiss-standard Swift Clamp. And like all Acratech products I’ve ever used, it just works. It makes the Black Rapid strap fully practical, and is 100% reliable. The best addition to my setup for this trip, and highly recommended.

Olympus Zuiko 150mm f/2 lens

Hmm. What to say about this.  I desperately wanted this lens, especially for wildlife. And when the subject calls for it, it is indeed sensational. It even works well with the 2x teleconverter. It does, sometimes, have trouble acquiring focus, even without the teleconverter, although this may be in part due to my inexperience with this type of lens and focus limiters. The SWD autofocus on the 50-200 is faster, although that lens still suffers, sometimes, from hunting or total AF failure in some cases. The results can be quite remarkable, but Lord is it heavy! I frequently bitterly regretted dragging it around Argentina, and I may well sell it. It’s undeniably a fabulous lens, but it isn’t very practical for travelling around with.

Olympus E-5 and E-3

Well, the Olympus E-5 was not bought for this trip, neither was the E-3 which was dragged out of retirement as a backup / second body. But they both deserve an honourable mention for once again putting up with the worse conditions I could subject them too, including very frequent drenching, without skipping a beat. Both worked flawlessy, although it was a revelation to realise just how much better the E-5 is over the E-3 in terms of dynamic range. Also in side by side use, I did find that the slightly different control layout of the E-5 is easier to use in cold conditions. Yes, they’re heavy, yes they’re “only” four-thirds sensors, but in terms of field use they’re the equal of top-end Canons and Nikons is most situations. And a lot cheaper.

The Inevitable

Proud owner of a Sigma DP2 Merrill

in GAS , Monday, December 10, 2012

Well I cracked. I bought a Sigma DP2 Merrill. So I now have, er, 5 cameras. And a few “backups”. Better than spending it on booze I suppose. Anyway, the DP2M has been written about to death all over the place. Suffice it to say that it is everything I expected it to be, for better and for worse. So far the photos seem pretty good, and yes, I got the “wow!” reaction when I first zoomed in. Somebody somewhere compared it conceptually to the big Fuji rangefinders: I used to have a 670GW, which I regret selling, and yes, the DP2M seems to occupy a similar niche - fantastic when all appropriate ducks are in a row, totally useless otherwise.

It’s not so easy to live without a viewfinder, so I’ve ordered the Sigma clip-on. I’m not entirely sure how useful it will be without any information display. Same as the Ricoh GRD I suppose.

The Sigma PhotoPro software, in my opinion, is nowhere near as awful as it is reported to be. It does what it is supposed to do, and has some more the adequate exposure controls. The exposure balance tool is an interesting idea which I don’t think I’ve seen elsewhere. The DP2M (and DP1M) is not easy to find in Switzerland, but I got mine at a low price with amazingly fast delivery from Digitech in Zürich.

And now for some pretty pictures from my first wander around:
