Flip Flop

indecision strikes again

in Film , Friday, November 22, 2019

Hello? Anybody still reading this stuff? Not that I’m writing anything…  So, I had a mega post ready to go a few weeks back, with the title “Everything Must Go”, and the content was exactly what the title said. I was putting up for sale all my film cameras (Hasselblad XPan, Linhof 612 and Voigtländer Bessa 667), and getting out of film. My main motivation was (is?) to reduce clutter, both physical and intellectual, and to use only tools which enable a painless workflow, so, in my mind as it was two weeks ago, digital. And to be more precise, Olympus digital - I had decided that my experiment with the Sigma sd H was a failure, but I would hold off a little before putting that on the market as well (the dp0 Quattro is here to stay though). I still had a few rolls of film either out for processing or about to go, evidence of my very half-hearted, token engagement with the medium in 2019.

And then the processed film came back…

B667 2019 09 03

So, a photo of nothing much really, but my oh my, that Portra 400 look is just so luscious. There’s no better way to capture that southern Italian light (Bessa 667).

Xpan 2019 02 14

This was supposed to be a farewell, rattling through half a roll of Ektachrome E100 so that I could take it out of the camera before selling it.  And then I saw the result… oh, and I forgot to put the centre filter back on after cleaning it resale, giving a trendy vignetted look (XPan II).

L612 2019 02

This is the least convincing. Well, the location I’d set out to photograph turned out to be the location a couple had chosen for a romantic picnic, so I was really scraping the bottom of the barrel here. Still, those Fuji 160 Pro greens….  And, unfortunately, the 58mm lens flare (Linhof 612PCII).

So I’m back on the fence. On top of all this, it seems I could be giving up film just at the wrong time (typically), if reports on Kodak ramping up production and Fuji bringing back colour film are accurate.

Actually a secondary motivation was to just maybe raise the funds to buy a Hasselblad X1D Mark II. But then I downloaded some raw files from that camera, opened them up in Lightroom, and to be honest, the only major difference between them and Olympus OM-D files are that they’re bigger. Far off detail still breaks down into exactly the same unattractive mush as for the Olympus (neither film nor Sigma Foveon do this). There might be a touch more dynamic range, and just possible more subtlety in colour gradients, but we’re still not in Kodak Porta territory. Far from it. And the cost, especially of the lenses, is just ridiculous for some amateur dilettante like me. Anyway, we’ll see.

Same goes for film. Right now I don’t have any immediate use for it, but I guess it is probably best to leave that particular bridge unburnt, for now.

The Great Pano Bake-off

mirror mirror on the wall…

in Scanning , Monday, July 31, 2017

Having now added a Linhof 612 to my arsenal of wide-screen photographic tools, the time has come for a showdown. Which, if any, is the best? 

The candidates are, then:

  • Linhof 612 Medium Format film camera
  • Hasselblad XPan 35mm film camera
  • Sigma dp0 Quattro digital camera with Foveon sensor, 21:9 frame ratio

Now, you may say that I could substitute any digital camera for the dp0, and “just crop”. Well, you could, but I can’t, because accurate composition through the viewfinder is important to me. The dp0 comes close to the XPan with its wider lenses, but as far as I know all Sigma Quattro cameras, so dp0, dp1, dp2, dp3, sd and sd-H offer a 21:9 crop. I don’t know of any other cameras which do.

I’ve compared the dp0 with the XPan in the past, and concluded that the Sigma is certainly a valid contender for the title of “digital XPan”. Indeed, it replaced the XPan in my camera bag on my last trips to Iceland and Antarctica. But the Linhof, surely, with its huge frame size, should come out of top ?

For the film cameras of course we have another factor in the equation: the scanner. I’m pretty sure that the OpticFilm 120 at 5300dpi extracts at least 90% of the potential resolution from the exposed film, but I’m not fully convinced that it reaches 100%. Possibly a drum scanner or a Hasselblad Flextight could do marginally better, but if it takes a €15000+ scanner to outdo a €900 Sigma camera, then we’d be be getting into the realms of insanity.

Of course, the relative file sizes are a bit scary.  But I’ve got lots of disk space.

  • Linhof: 24533 x 11245 pixels, 1.5Gb
  • XPan: 13516 x 4986 pixels, 395Mb
  • Sigma: 5424 x 2328 pixels, 73Mb

For the test, I trudged up (and down) to a local valley stream, set up the tripod, and shot frames from each camera. The scene was initially framed using the Linhof. The Linhof was loaded with Fuji Provia 100F, and had the 65mm lens mounted. The XPan, sadly, was loaded with Rollei Variochrome, set at ISO 200, in a parallel test described previously. I shot XPan frames with both the 45mm and 30mm lenses.  The Sigma of course had its fixed 14mm lens, which is roughly equivalent to 21mm for so-called “full frame”.

I was interested in two aspects: the different frame coverage, and the comparative resolution of each system. Colour was not really relevant in this particular exercise, although the differences are interesting.  But anyway I haven’t even attempted to try to match colour.

So, here are the “results”.  First, the comparative frame coverage.

panocompare_fullwidth

Clockwise from top left: Sigma dp0, Linhof 612 65mm, XPan 45mm, XPan 30mm.

It’s difficult, but please ignore the horrendous colour of the XPan frames. The scans are all “flat” from Silverfast - I have not attempted any kind of colour correction. The first thing that jumps out for me is how close the Sigma and Linhof are. I could get even closer by shooting a 2:3 frame on the Sigma and cropping it. The Linhof is just a touch wider. The XPan 30mm is the widest of all, and its vertical coverage is very similar to the Linhof. The XPan 45mm, in this company, and for this scene, is a bit neither here nor there.

Note, any attempt at choosing a “favourite” shot here is rather pointless. As I said above, the shot was framed for the Linhof, with the tripod remaining fixed for the other three, so I would expect (and indeed hope) to prefer the Linhof composition.

Working with the Linhof over the past month or so has confirmed my attachment to the (almost) 2:1 ratio. The Sigma ratio is actually closer than I expected, because the actual size of the exposed film on the Linhof is 12 x 5.5, so somewhat wider than a nominal 2:1. The Linhof has just one trick up its sleeve, but its a good one: the 8mm shift is hugely useful for this kind of shot. Note the difference between the Linhof and XPan 30mm frames: thanks to the shift (negative in this case), I’m able to put the extra vertical coverage to better use, without tilting up or down and hence distorting the perspective.  This limitation has always frustrated me with the XPan.

Now for resolution. Remember, with the Sigma, it being a digital camera with a Foveon 3 layer sensor, we can magnify up to 100% and expect sharp results.  With the film cameras it is way more complicated.  We need to factor in focussing (hyperfocal in this case), film flatness, film curl when scanning, scanner lens quality, scanner depth of field, and all the general characteristics of an analog to digital conversion.  Suffice it to say, film looks best on the light table, and goes downhill from then onwards. All we can do is damage limitation.

Having said all that, let’s look at a 100% section of each shot:

panocompare_100

100%: clockwise from top left: Sigma dp0, XPan 30mm, Linhof 612 65mm, XPan 45mm

In terms of numeric resolution, the Linhof clearly wins, but the level of actual information is debatable. There has been no sharpening applied here, so for the film shots what you see is what you get out of the scanner. What does appear to be the case is that the XPan lenses are actually sharper than the Schneider 65mm lens on the Linhof. One thing I’m finding with the Linhof is that objects at infinity seem to be quite soft, regardless of the focussing. I have no idea why this should be, but since focussing is by scale only, it isn’t straightforward to verify. Again, there are a lot of variables in the system.

Another way to compare is to try to adjust zoom to get roughly the same field of view, as follows.  Since the Sigma has the lowest nominal resolution, it defines the baseline.

panocompare_match

Matched view: clockwise from top left: Sigma dp0, XPan 30mm, Linhof 612 65mm, XPan 45mm

Now there’s not so much in it. The XPan with 45mm trails slightly, at least in this example, but otherwise the level of detail is close. Probably if the XPan had been loaded with Provia 100F then the difference would be smaller. With the Sigma there is a higher level of micro-contrast and acuity, but appropriate processing of the film images can close the gap.

Note, when printing these images at the maximum size I can achieve on my A2 printer, in all cases there is quite sufficient resolution, so this exercise in pixel peeping should be taken with several grains of salt.

However, the clear conclusion is so far that the Sigma dp0, which is more practical, lighter, considerably less expensive and offers immediate feedback, is pretty much a match for either of the film cameras on a technical level. To be honest it is probably the best of the three, in purely technical terms, and in the right conditions.

Let’s briefly compare the dp0 just with the Linhof:

panocompare_dp0_linhof

Top: Sigma dp0, Bottom: Linhof 612 65mm

The Sigma definitely seems to give slightly more real resolution, although there is a hint of some variation across the frame from the Linhof. But in the best case scenario, the Linhof / Plustek OpticFilm 120 combination is a match for the Sigma dp0 in terms of effective resolution - no more.

So why use the Linhof, and why use film at all? Well, all is not rosy in the Sigma world. Although it is not too apparent in this frame, it transitions to over-exposures in a very harsh and unpleasant way. With scenes featuring flowing water, for example, you need to be extremely careful with exposure.  And since the Sigma’s output is nowhere near as malleable as that of almost all other modern digital cameras, you have to very careful indeed. Actually it is this poor handling of highlights which makes more hesitate about investing in the Sigma sd Quattro system.

Of course, you also have to be careful with slide film, but even slide film with its aversion to highlight overexposure handles transition to burn-out much more naturally.  The Linhof also features one of the absolute best viewfinders ever made. If in-the-field composition is important to you, as opposed to fix-it-in-Photoshop, then this is a big deal.  And finally, the killer feature, the “permanent shift” lens, which avoids the Achilles’ Heel of panoramic photography, vertical entering of compositions.

And what about the poor old XPan? Well, it too has its advantages. First, the 30mm lens gives a wider field of view than either of the other two (although a Linhof 612PCII with 58mm lens would be wider).  The XPan also has a rangefinder, making manual focus very simple, and very reliable auto exposure.  And it is a quarter of the size of the Linhof 612. I’ve been using it for 17 years, and it’s not for sale. Yet.

And finally colour - although I like the colour output of the Sigma, it can be a little weird. Actually in the example here I used a custom colour profile in Lightroom. The rendition of Provia 100F, once the blue shadow cast is removed, is to my eyes more natural.  There is also something ever so slightly sterile about the Sigma output.

But finally, all three are great cameras which give me a lot of satisfaction.  If I was pushed to produce something on a tight deadline, if the subject permitted it I’d probably use the Sigma.  If I wanted the best control of composition I’d use the Linhof, with Provia 100F for landscape or Portrait 400 for urban work.  For maximum flexibility and discretion, the XPan.  In all three cases, I’d be able to print as large as I am able to with no compromises.

But I would love to see a drum scan of a Linhof 612 shot…

Scattered thoughts gathered together

There’s not a huge amount going on in these parts on the photography front right now, but I’m carrying on with getting familiar with the Linhof.  I took it on a recent short break in Provence, and used it as a point and shoot.  It got me a few curious glances (the sort that crazy people get), and maybe a couple of atmospheric shots.

1972 wants its soundtrack back.

Been a long time comin’

Linhof 612 PC in da house!

in GAS , Monday, June 12, 2017

Back in December 2000 I was traveling around New Zealand, with my new XPan, and new girlfriend. I’ve still got them both. I’d been eyeing the XPan for a few years, but up until earlier that year I couldn’t afford it. However, an upturn in my fortunes allowed me to buy the camera and full set of lenses. I was pretty much smitten by the XPan, and still am, but little did I know that I was about to get a serious case of grass is always greener syndrome.

At some point during the trip I picked up a book of landscape photography by NZ photographer Andris Apse. The luscious, classic panoramic photography within its pages is exactly what I was into at the time. Reading the introduction, I was quite surprised to discover the existence of something called a “Linhof Technorama”, and even more by Apse’s reasoning that the relatively restricted 6x12 field of view was the sweet spot. His photographs provided (and continue to provide) strong justification for this. Suddenly I had doubts about my XPan.

However, on returning home to Switzerland, I investigated a little more, and both the price, and the challenges inherent in using the Linhof convinced me that the XPan was good enough for me. Naturally I then went and did something totally irrational and bought a Hasselblad ArcBody, which first, uses a square format which I never really got on with, and second, makes the Linhof look like a Point & Shoot. Looking back, I really regret not buying a Technorama 612 at 2001 prices.

Over the years my interest in the Linhof waxed and waned, and I continued using the XPan. Indeed, I even destroyed my original copy and had to buy a new one. But I also discovered the rather unique feature of the Linhof, its “permanent shift” lenses. This seemed to adress a shortcoming I’d always felt that the XPan suffers from, which is the need to vertically center the horizon to avoid obvious distortion. This isn’t always a problem, but in some situations it is a bit of a showstopper. The “permanently” part of “permanent shift” gave some food for thought, but still, it was nagging at me.

Anyway. I’ve got one. After years of lurking on eBay, finally one came up at a reasonable price, sold by an actual working photographer as opposed to some anonymous combine in South Korea or Japan (seems about 75% of the production run ended up in South Korea. Perhaps they throw them at the Norks), and just down the road in Milano. It’s an original model (not a PCII) with 65mm lens. It’s not so easy working out the vintage of Linhof 612s, as there seem to be quite a lot of minor variations over time, but I suppose this one must date back to the late 1980s. In any case, it was built to last, and it certainly has. I’ll write some more about what I’ve been able to work out about the production history of the Linhof 612, since I can’t actually find this anywhere else.

I did have an option of buying a brand new PCII from Linhof, with, apparently, the very last production 58mm lens in the factory, but the price, which has inflated way over inflation over the last decade, was just too high. Having said that, a German eBay seller is/was offering a new PCII kit for around €10’000, which really is ridiculous. Sadly it seems that Linhofs have gained the same attraction to collectors as Leicas these days. Ten or so years ago, the same kit would retail at about €5’000, which is already quite enough for a fully mechanical camera with no lightmeter. Then again, people pay more for a Leica M-A and lens.

The build quality of the Linhof is awe-inspring though. Not so much built like a tank, more like carved out of a tank. And it’s not just a box. It has a high precision film transport, and a series of interlocks which by and large stop you doing anything stupid. For example, you can’t remove the lens when the dark slide isn’t inserted. It’s simple, but extremely well designed. It makes the Lomography Belair look very, very stupid.

I’ve got 3 developed rolls from the camera so far, so 18 frames, and operationally speaking it seems fine. I did repeat 3 shots because I was convinced I’d left the lens cap on - I hadn’t. I took one shot by accident, when I had the shutter lock off. And so far, inevitably, it’s my favourite.

“Honour thy mistake as a hidden intention” - Linhof 612, Portra 400

Finally, my Plustek OpticFilm 120 has got something to really get its teeth into. I realised pretty quickly that scanning at 5300dpi wasn’t a terribly good idea. A print from such a file at 300dpi would cover half my house. The Schneider 65mm lens seems pretty sharp, although I’m slightly unsure if it focussing correctly at infinity. I’ll need a few more disciplined shots to be sure. So far it’s mostly handheld!

Well, I’m sure I’ll be posting more about this. I’ve been waiting 16 years to get my hands on this camera, and I fully intend to enjoy it.

Eccentric or More Eccentric ?

widescreen addiction

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:

drm__20160507_DP0Q0317.jpg

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)

drm__20160507_DP0Q0317-2.jpg

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…
