Just some stuff about photography


New Panoramics

in Photography , Wednesday, August 17, 2016

Wide format, or "panoramic" photography for me has been synonymous with film and my Hasselblad XPan, since the turn of the century. Well, it seems, no more. On my recent trip to Iceland, for the first time, it stayed at home, and its usurper, the Sigma DP0, came instead. And I really enjoyed using it. You'll find all sorts of opinions and views all over the darker corners of the photo-net droning on about how awful it is, but I ignored all that stuff and just used it. Once you get into the groove, it's really fun to use. The weird shape makes total sense when holding it, and it's a great conversation starter (if you like conversations that start with "what the hell is that!?").

These little renditions below don't really do justice to the jaw-dropping impact of the detail and delicacy seen on a print or big screen, but they go somewhere, I hope, to explaining why the unconventional approach and, er, idiosyncratic software is worth the trouble. Speaking of which, maybe I'm just lucky, but unlike for certain well known pundits, Sigma's PhotoPro software is 100% rock solid for me. I can't remember the last time it crashed, if ever.

But anyway, it's all about the photos, not the gadgetry, and I'm pretty happy with this set.









So... anybody want to buy an XPan ?

Eccentric or More Eccentric ?

in GAS , Thursday, May 19, 2016

I’m still trying to convince myself I don’t want a Linhof 612, even though I have my eye on a very nice looking one which I can almost afford.

The thing is, it’s a purely mechanical camera. There is no preview of focussing. No metering. It’s just a (extremely high precision-engineered) box with a (breathtakingly gorgeous) lens on the front. It’s heavy, a pain to use, and has this intriguing but rather eccentric 8mm fixed shift.

And I have a Sigma Dp0, which is not only a pain to use, looks plain weird, and draws attention like bears to honey.  But it has auto focus, a screen (just about), and doesn’t need the film processing or scanning steps - albeit it does need Sigma Photo Pro, which rather evens the score.  And it has a (breathtakingly gorgeous) lens on the front.

This is what the Dp0 can do:


Not bad - almost Ektachrome-like.  The ratio here is 21:9, which is actually shown on the screen, allowing exact composition. Of course you can crop any image any way you want, but that doesn’t work for me.  I need to see what I’m doing, and I need my composition to be preserved in the file. The Dp0 / Sigma Photo Pro combination does both.

If I’d shot this with a Linhof, I’d probably have framed it like this (although the lens field of view would be a little different, but I think the Dp0 17mm lens corresponds roughly to a Linhof 58mm)


Of course, had I shot it on a Linhof I’d probably have got the exposure and the focussing wrong. And then Silverfast and / or my scanner would have crashed trying to deal with the huge file.

Common sense says Sigma - and given how unlikely that sounds, in the general scheme of things, it says all I really need to know about the sense of buying a Linhof 612 in 2016…

The Digital XPan, by Sigma

in Sigma , Wednesday, March 09, 2016

I bought my first Hasselblad XPan in 2000, and in the following 15+ years, I’ve accumulated a large shelf full of binders of negatives and (mainly) slides. I bought it because I liked the widescreen format, and I still do. Although a niche camera, the XPan was pretty popular, initially principally with landscape photographers, many of whom used one alongside an SLR. For me, it was the other way around - the SLR was the “second camera”. The XPan started to fade from view with the advent of DSLRs, and Hasselblad/Fuji stopped producing it in 2006, citing some story about a circuit board not being compliant with some convenient European regulations on lead content.

In recent years it has seen something of a revival, and secondhand prices for good copies have risen higher than the original retail. It seems to be riding a lot on the “back to film” movement, and the accompanying mystique. But there do not seem to be many people around who, like me, bought one back near the release date and never stopped using it.  And even fewer people who shoot slide film (still). It seems to be quite popular nowadays for “street” photography, where the unusual frame gives a novelty effect that compensates for many a shortcoming in the photograph. However, with the lenses having a maximum aperture of f/4, and rangefinder focusing, I’m not personally convinced it is that ideal for street. But I’m no authority on the matter.

For me the biggest frustration with the XPan has nothing directly to do with the camera, but with the rapidly shrinking availability of slide film.  My favourites, Kodak E100G and Fuji Velvia 100F (nothing like the infamous Velvia 50 by the way) have long since departed, Fuji Provia 400X is more or less gone, and the only serious choice left is Fuji Provia 100F, which I never much liked. The revival of Ferrania Film is, so far, inconclusive - initial batches of new film are close to a year overdue. Of course the choices in negative film are a little wider. I like Kodak Porta 400, but it only really suits brightly lit urban scenes. Kodak Ektar 100 is ghastly. And I’m a colour photographer by instinct, not black & white. On top of all of this, the bottom has fallen out of both semi-pro E6 processing, and of the semi-pro film scanner market.  So not only is the writing on the wall, but it’s on every wall in every direction.

So, there’s been a lot of calls, directed mainly at Fuji and Hasselblad, to produce a “Digital XPan”. There’s a snag there, though, because a digital sensor covering the full 65x24 XPan format - two “full frame” sensors side by side -  would be horrendously expensive, even though this seems to be what people want. So the question arises, what do we actually mean by “Digital XPan” ? What are the key features ? Would everybody agree? The answer to the last question is obviously a resounding “no”.

The key features of the XPan, technical and otherwise, are:

  • Native “panoramic” double-frame format
  • On-the-fly selectable standard 35mm frame format
  • Rangefinder manual focussing
  • TTL electronic metering
  • Offbeat, unusual camera
  • Built like a tank
  • Interchangeable lenses
  • Very high quality - and expensive - glass
  • Oh yeah… film

Personally, the key feature is the first: a camera which records what-you-see-is-what-you-get panoramic format with a dedicated panoramic viewfinder. In-camera composition is very important to my way of doing and enjoying photography, and for me cropping in Photoshop as some kind of afterthought rarely produces a strong, satisfying image. I emphasise, for me: clearly other people have different opinions. As for film, I’ll fall back again on a quote from one of my heroes of panoramic photography, Stuart Klipper, who when asked why he (still) uses film, replied “because that’s what the Linhof takes”.

So, yes, you can certainly obtain a panoramic frame from any digital camera through post-processing. Many compact cameras also have a 16:9 framing option which you can squint at while holding the camera at arms length in front of your face. But this is simply not the “XPan experience” for me. It doesn’t inspire me, and it doesn’t give me the thrill that seeing the world through the XPan rangefinder does.

And that’s a good time to introduce you to the other camera on the stage here, the Sigma DP0.


Sigma DP0 with viewfinder, and Hasselblad XPan

I’ve been using Sigma cameras with their unique Foveon sensor since the 50mm-equivalent DP2 Merrill. As I, and many others have written, when these cameras get their ducks in a row, they are truly fabulous. The rest of the time they’re a disaster area. A while back, Sigma introduced a new lineup, using the revised Quattro sensor. They also introduced what would be politely described as an unusual body design. A lot of people were aghast at this. I thought it was fantastic. But I didn’t buy one at the time, as the DP2M & DP3M I already owned were quite enough.  But then came the announcement of the DP0 ultra wide (21mm equivalent), and buried deep down in the specification, the 21:9 framing option. It seemed that somebody in Japan was thinking along the same lines as me.


The DP0 21:9 aspect ratio

So eventually, after a lot of indecision, I got one, along with the hood viewfinder attachment which allows eye-level composition, which as I have said is a must-have for me, and has the additional benefit of making an already strange looking device look downright weird. It’s certainly a conversation starter.

The 21:9 aspect ratio is a bit deeper than the XPan. It is about halfway between the standard 6x12 and 6x17 ratios - the XPan is slightly taller than 6x17. This is actually fine by me. I often found the XPan format a smidgen too wide, and I’ve always pined for a 612 camera. The resolution of the 21:9 DP0 image (5424 x 2324) is approximately half that of an XPan frame scanned at 4000dpi (around 12200 x 4700), but of course the two are not directly comparable. The actual information content is very similar. Of course, the DP0 has a fixed lens, whereas the XPan has three native lenses to choose from (as well as some other fairly dodgy choices via adaptor). The DP0’s 21mm equivalent lens gives a field of view roughly equivalent to the XPan 45mm lens. And they’re both f/4. And both extremely good quality lenses.

Anyway, that’s an awful lot of babble before getting on to the core of the matter: how do they actually compare ? Well, I don’t do “tests” as such, I really cannot be bothered. But recently I took the DP0 to make a few photos in the nearby Golle della Breggia, in a location I remembered shooting with the XPan a few years back.

Sigma DP0, processed in Sigma Photo Pro v6.3.2

Of course, these photos are taken at different times of the year, different times of the day, and with different framing, never mind with completely different technology. The only common factor was the photographer. Given that, to my eyes at least they have a quite remarkably similar rendering of colour and tonality. The Minolta scanner, which I have now replaced, also developed a tendency to exaggerate red in the midtowns, which I clearly did not sufficiently correct here. I could certainly get the two photos to look very close in rendition with a few minutes work, but that isn’t the point: what I’m looking to decide is if the DP0 can assume the role of the XPan for me, and I’m tending to believe it can, so far.

It is also interesting to compare resolution. Here again, there is a degree of subjectivity, as the scan is not necessarily optimum, and here no sharpening has been applied (although Sigma Photo Pro allegedly always applies some sharpening). I’ve tried to match two roughly similar areas of the photos, with the DP0 crop at 1:1, and the XPan reduced more or less to match.


Sigma DP0



So, very, very subjective, but it does look like the Sigma’s Quattro sensor is a match for 4000dpi scanned 35mm Kodak E100G. Not actually a big surprise, although it is probable that with a bit of work I could extract a little more detail from the film.

The XPan still has at least two advantages - the 30mm and 90mm lenses. But in terms of overall end to end user experience, there is a remarkable similarity between the two cameras. Indeed, it can be as time consuming to extract a processed file from Sigma Photo Pro as it is to make a good film scan…

One are where the DP0 wins outright, however, is low light photography. You can do long exposures on film, but dealing with reciprocity failure is painful, especially with slide film. The DP0, on the other hand, will cheerfully make an exposure up to 30 seconds (but no more, let’s not carried away here).  Also, I really like the way the Foveon sensors (both Merrill and Quattro) render tungsten lighting. So to wrap up here are a few shots from my first major outing with the DP0 in Venice.


It is tempting to draw a conclusion from the fact that since I’ve owned the DP0, the XPan has sat on the shelf. But it is early days yet, and there haven’t really been many opportunities to use it recently. I certainly wasn’t going to take it to Colombia. There are also some situations in which I don’t really trust the Sigmas, in particular snow and ice.  And although the Quattro has much better battery life than the Merrill, it’s still pushing it to reach 100 shots.  Then again, processing 100 shots in Sigma Photo Pro takes roughly a decade, so perhaps it’s just as well.

But I’ll repeat what I’ve said before: the Sigma DP0, with the LCD viewfinder, set at 21:9, is the closest digital camera I’ve found so far in terms of handling and user experience to the Hasselblad XPan. And it’s a great camera in its own right, fun to use and with devastatingly high quality output.

A trip to San Pietro

in Photography , Wednesday, January 13, 2016


Despite many visits to Venice, the eastern, seaward end of the city has always eluded me. So on my last visit I was determined to make this my focal point. I have to admit from the glimpses I had in the past, I expect something more like the apartment blocks of the outer reaches of Cannaregio, or even Sacca Fisola. While there is an element of this, in fact I discovered that the area cut through by via Garibaldi has a quite distinctive character, subtly different to any other part of Venice. However the part that really caught my imagination is the little island of San Pietro, right at the northern tip.  A few hundred years ago I imagine San Pietro was not the quiet backwater it is today. The Basilica di San Pietro di Castello was in fact up until 1807 the city’s cathedral church, even though St Mark’s was already more dominant. But now it is very peaceful, and only dedicated tourists venture this far away from the fake Burano glass and carnival mask sellers.

Actually, I didn’t even go into the Basilica. Churches aren’t really my thing. I did open the door, but on seeing the inevitable ticket booth, I declined to go further. If the Catholic Church has decided that the primary purpose of ecclesiastical architecture is to make money, then it is hardly surprising that the only relevance it has today in much of the world is to tourists. I’m quite happy to make donations, but even an agnostic such as I am looks as much for a sense of the spiritual in a church as a collection of mouldy, dark old paintings by some vaguely famous Italian bloke. And that sense is stopped in its tracks by a ticket booth.

But anyway, it hardly mattered, because the visual treasure trove was immediately next door, in and around an old colonnaded courtyard backing on to the Basilica.  I can’t actually find a reference to this place, and I suspect it is in a fleeting state of transition between out of bounds Church property and a luxury development of charming residences with Genuine Venetian Fittings™. It was marked “private”, but I spent at least two hours wandering around, and the two or three people I saw there didn’t seem to mind. They obviously thought I was a bit weird, though.

Not that I would know anything about it - despite a brief dabble - but this seems the perfect location for a certain genre of portrait photography. Since I didn’t have one to hand, I’m afraid you’ll just have to imagine the models, in the set below.


All photos from Sigma DP0, except the first and second after the text, which are Kodak Portra 400 / Voigtländer Bessa III

Film, or Foveon ?

in Sigma , Wednesday, January 06, 2016

Ah, the eternal quandary of the dilettante art photographer: film, or digital ? And if digital, which kind of digital ?  For many, the ultimate expression of film in these End Days is Kodak Portra 400, with its oh so aesthetic transparent, lucid, indeed filmic quality. Or to put it another way, washed out. And that description is not exactly unreminiscent of the way Sigma Foveon digital sensors paint the world. So, which is “better” ? The two examples here offer no conclusion, are not a test, and make nothing other than an observation.  And they’re taken with completely different lenses, so obviously the framing and viewpoint are quite different (the sign on the wall at the left of the second photo can be seen on the right of the first, beneath the stairs).  But the scene, lighting and time of day are the same.

The first, on Portra 400 120 roll film, was taken using my Voigtländer Bessa III (aka Fuji GF670). It has an 80mm lens, so near enough 50mm in old money equivalence. It’s probably the last (serious) medium format film camera ever to be designed, and it’s probably the best fixed lens MF rangefinder ever. The rendering of the Porta 400 film was entrusted to Silverfast’s NegaFix tool, scanned at 5300dpi on the OpticFilm, which at this setting easily resolves grain.


The second was taken using the quite remarkable (in several senses of the word) Sigma DP0 Quattro.  This has a Foveon Quattro sensor producing a file roughly equivalent, so they say, to a standard 39Mpix sensor. Which is quite big enough. More to the point, it produces absolutely gorgeous, natural, transparent, lucid, indeed filmic colours. In my opinion, anyway. In this case the lens is a highly corrected, good enough for architecture, 14mm, which is near enough to 21mm in old money.


So which is best ? I don’t know. I’m happy with both. They don’t call me Indecisive Dave for nothing, you know. One might expect digital to be more convenient than film, but Sigma levelled that one with a (ahem) fabulous piece of mandatory software called Sigma Photo Pro. Of course, I could also have compare with my standard, sensible Olympus digital camera. But there’s no fun in being sensible.
