HDR with film

true grit

in Film , Sunday, September 25, 2011

I took a set of XPan frames of a scene in Iceland back in 2009, with the express purpose of seeing if I could make an HDR composite from them, and get the gritty, high contrast, low saturation “grim up north” look so beloved of brands such as 66 North.

There are 3 exposures, one “normal”, one 1 stop below, one 1 stop above. I decided to try running them through Nik HDR Efex (NHE from now on).  On the first try I fell at the first hurdle. Although NHE has an auto-align feature, it cannot cope with input images with different sizes. Since I had tidied the scans up a bit, they were all slightly different.

The 0EV (middle) exposure

So I rescanned all three using exactly the same size, and tried again. Unfortunately, it is absolutely impossible to get three completely independent scans exactly aligned, so alignment was still required. At least now they were the same size. So, back into NHE. The input processing takes something like 15 minutes or more with these large images, but again the results were hopeless. The alignment was completely off.

So I decided to try pre-aligning with Photoshop’s Auto Align. This worked fine, very well in fact. So having nearly perfectly aligned images, I fed them back into NHE. And 15 minutes later, NHE mangled them way out of alignment. Back to the drawing board. I turned off “alignment” in NHE, and gave it another go. This time it worked, or well enough.  In terms of alignment there are still some artifacts at 100% zoom but for smaller viewing sizes it works.

So then it was off to fiddling with the wide range of settings in NHE, and eventually I got something close to what I wanted.

The HDR look: Somewhere grim in the Westfjords

However, with film as the input, NHE makes grain explode. I had to do a lot of cleaning up, especially in the sky, and the results are most certainly gritty.

It would probably have been a lot easier to do it with digital, but there is a rather unique look coming out of film here, and have got a process that sort of works, I might try refining it.

Widelife

an anecdote from the archives

in Hasselblad XPan , Sunday, July 10, 2011

The Hasselblad XPan is not noted for it’s usefulness in wildlife photography, still less in birding. The longest lens is a 90mm f4, which equates roughly to a 50mm in “normal” 35mm terms. Arguably.

So when I was looking for something to scan today (it was raining), I came across a very untypical series of shots I took at Latrabjarg, Iceland, in 2004. That day - or rather night - I was photographing puffins using my Olympus E-1 with 50-200mm lens (that’s 400mm in 35mm terms), when the battery died. And I didn’t have a spare with me, and the spare was about 20km away. Bugger.

So,throwing convention to the wind, and to the amusement of my companions, I switched to the XPan. There can’t be many other places in the world you can get close enough to wildlife, even less birds, to get away with this, but these puffins have no predators on land, and really couldn’t give a damn about some strange animal crawling towards them waving a weird object.  Of course they didn’t really stand still long enough to get many shots - this is shot on ISO 100 Velvia 100F, at f4 I imagine. Maybe 5.6 at a push.

But still, it sort of works, and is vastly different from the standard DSLR shots I got once the battery was recharged.

p.s. Afterwards, I discovered that the E-1’s battery has a sort of “rebound” effect. Leave it off for a bit, switch in on again, and you’re good to go for another 50 shots or so. Same goes for the E-400, but not the E-3, which eats batteries like a pig in donut shop.  Anyway, in this case I’m glad I didn’t know, I’d never have even considered this otherwise!

Ethical quandry

to edit, or not to edit ?

in Film , Saturday, May 21, 2011

I recently spent some time on the Eolian Islands, out of season, avoiding the (extreme) heat and the tourists. While I was there I visited one of my favourite locations, the main crater of Vulcano, a couple of times.

I was to find that since my last visit, the crater floor had been adorned by some “urban art” in the form of stones spelling out various declarations.

Vulcano crater scan

Straight from the scanner: the crater floor

I don’t really want to start a rant about this. Some people will find it unacceptable, to the point of wanting the perpetrators skinned alive (and they’ll likely as not have British or German passports), others will just take it as part of the scenery, others will find it amusing. The question is, should I include it in my photograph ? Certainly the last I time I visited, it wasn’t there, or at least if it was I didn’t notice, so it wasn’t in my pre-conceived photo either.

Not quite what I had in mind

So should I edit it out ? It’s not a very challenging task in Photoshop CS3. Possibly even less so in CS5. But is it “cheating” or “wrong” ? It is after all a fairly major part of the scene, and there’s a very long tradition of graffiti in the Mediterranean area. Pompeii, for example, has plenty. So in fact it could be considered to augment the interest.

To start off with, I didn’t think too much of it. I’d decided right from the outset that first I was going to edit it out, and second, most probably, it was going to be converted to black and white. Like this:

Xpan vulcano11 2 07

What I had in mind

Apart from any ethical issues, am I actually playing it safe and traditional here, and churning out yet another boring, bland photo with nothing to say for itself ? Justified, worthwhile edit - or lost opportunity ?

I’m really not so sure…

Svalbard panorama gallery

A salvage operation

in Hasselblad XPan , Friday, October 15, 2010

I’ve just added a Svalbard panorama gallery to the photography section.

This includes 16 photos taken from the 8.5 rolls of film I managed to salvage after my XPan disaster. Inevitably there’s a little too much overlap in location, but I thought they were worth sharing.

There are a few glitches in the layout of the gallery pages. I need to fix these. And some other stuff ... time fades away.

Son of XPan

Another walk on the wide side

in Hasselblad XPan , Tuesday, September 14, 2010

And on the third day…

the postman delivered a large box, which contained a much smaller dark blue box, which contained lots of other boxes of different sizes, which when opened and their contents put together, looked something like this:

_0012623.jpg

An absolutely pristine, practically unused Hasselblad XPan II! And what’s more, acquired at a scarcely believable price from Mifsuds in Devon, England. These cameras go for insane prices on EBay, way more than could ever be justified, but I got it for less than the original RRP.

I’m currently running a quick test roll through it (not that there’s anything quick about film these days), so fingers crossed.

One slightly weird thing: when the power is off, the exposure counter LCD stays on. It didn’t do that on the XPan I. Still, I don’t suppose an LCD drains much power…
