4x5 Woes: Mills, Birds And A Leak

You know, one of the most satisfying things for me these days is to spend a day at an interesting location and take six or twelve pictures with a 4x5 large format camera.

Leak

It's hard work. It means to carry a heavy-ish bag over your shoulder and a tripod with a big camera attached to its end. It means to thoroughly set up the camera, check the angles, open the shutter, stick your head under a black cloth on a sunny day with temperatures in the 90s. To focus on the focusing screen, you use a loupe that's hanging around your neck. It means to use a hand-held light meter, fish a film cassette out of your bag, load the camera, set the aperture, set the shutter speed, hope that you didn't get any of the steps out of sequence, pull out the dark slide and finally take the shot.

It's error-prone too. It means that there are at least 10 different steps in the process of making one exposure where you can mess up. Accidental double exposure? Been there, have even done a triple exposure once. Forget to set the right aperture after metering? Yep, I have my share of overexposed large format negatives.

If it's that hard work and that error-prone, then why am I doing it? The answer is simple: in the end it's one of the most fun and rewarding experiences that I've had in a long time. Nothing beats creating something with your own hands and finally holding the result of that work in your hands. Or post it online for the world to see. Much more rewarding than any digital shot has ever been.

Over time you get better. Most errors you only do once, as it hurts to lose one out of just a few pictures you'll take that day.

Last weekend I brought my trusty Grafmatic film holder system, a revolver-type 6-shooter that allows you to keep 6 shots in one magazine. Very convenient, but also heavier than normal double cassettes. Which turned into yet another source of error. I accidentally brushed the Grafmatic at the wrong angle with my arm, while the dark slide was still pulled. This resulted in a nice big splash of light pouring onto the exposed negative for a brief time. Long enough to ruin the shot. So I thought.

I ended up actually being quite happy with it. Is it because it's one of my babies? Or is there something about a perfect 4x5 picture seemingly ruined by light leaking onto it?

Let me know what you think.

Here's another picture of the same day. And another one.

Wir sind Hummel, oder: 4 Blendenstufen Push sind Pillepalle

Es gibt Workshops und es gibt Workshops. Im Fall der aktuellen Absolut-Analog-Veranstaltung in unseren neuen Räumen in Tübingen, war es ganz klar einer der spezielleren. Und das im positiven Sinne. Mit Begeisterung und Spaß haben sich die Teilnehmer den unwirtlichen Lichtbedingungen gestellt, vor die wir sie geschubst haben und was dabei raus kam, seht ihr hier.

Der Push

Am Anfang zum Aufwärmen und dran gewöhnen haben wir erst mal mit einem Push über 2 Blendenstufen angefangen. Standardprozedur, nix wildes. Nur wer meinte, der Push wäre nur zum "heller machen" da oder zum verkürzen der Belichtungszeiten in dunklen Situationen, der durfte sich dann über die ungewohnte Kontrastausbeute freuen. Bei prallem Sonnenlicht. Steffens Klappfalter war da dann sogar etwas überfordert, weil er keine tausendstel Sekunde konnte. Ergebnis: herrlichste Kontraste im prallsten Licht.

Die Hummel

An dieser Stelle kurz die Anekdote mit der Hummel. Aerodynamiker haben dereinst behauptet, die Hummel könne aus physikalischer Sicht nicht fliegen. Verhältnis Körpergröße und Gewicht zu Flügelfläche oder so. Die Hummel hat nun mal leider von Aerodynamik so ziemlich überhaupt keine Ahnung und darum schlägt sie einfach mit den Flügeln und … fliegt.

Der Pull

Phase zwei - wir nennen sie jetzt einfach mal die Hummel-Phase - ist die mit dem Pull über drei Stufen. Also die Behandlung eines ISO-400-Films als hätte er ISO 50. Ausgeschrieben ist das die 8-fache Menge an Licht, die er eigentlich bekommen soll. In manch einem Online-Forum liest man, dass das nicht geht. Auch die Ausbeute an Entwicklungsrezepten, die man für diesen doch eher ungewöhnlichen Fall online so findet, ist so gering, dass man fast meinen möchte, es ginge tatsächlich nicht.

Alex pull
3-Stufen-Pull (Alex)

Aber wir waren einfach mal ganz Hummel, haben uns nicht verunsichern lassen, und die Ergebnisse sprechen tatsächlich deutlich für sich. In diesem Fall war das ein T-Max 400 in D-76, 1:1, 7min20sek bei 20°C.

Es geht halt doch, und zur Belohnung für den Ungehorsam bekamen die Fotografen dann herrlichste Grauverläufe mit extrem viel Detail und einem Kontrastumfang, der seinesgleichen sucht. Gut gemacht!

Was gelernt

Und auch wir selbst lernen jedes mal noch etwas dazu. In diesem Fall hatte ich (Chris) mir eine sehr kontrastreiche Situation (Innenraum mit Fenster und sonnenbeleuchteter Umgebung außen) geschnappt und eine Belichtungsreihe mit sieben Belichtungen mit je einer Blendenstufe Unterschied gemacht. Was am Ende hinten raus kam, hat selbst mich verblüfft.

Chris pull1 Chris pull2
Bild 1: 1/1000s, Bild 2: 1/15s

Die Ausarbeitung der Bilder wurde am Ende zwar noch minimal angepasst, aber alleine die Tatsache, dass der Film bei diesem 3-Stufen-Pull locker - und ohne irgendwo Zeichnung zu verlieren - diese sieben Blendenstufen breite Belichtungsspanne einfach so ohne zu murren wegsteckt, hat sogar mich weggehauen. Zieht man noch den gesamten Kontrastumfang der Szene in Betracht, dann wird hier eine Breite an Tonwerten erfasst, die fast unmöglich erscheint. Ich werde ab jetzt garantiert noch öfter Pullen. HDR? Wer braucht das? :)

Der Nachbrenner

Am Abend haben wir dann Phase 3 unseres gerissenen Plans gestartet und unter den Teilnehmern den Pushwettbewerb losgetreten. Zur blauen Stunde und zur tiefen Nacht. Wieviele Blendenstufen verträgt so ein TriX oder T-Max 400 wohl?

ISO 1600 - Moni
TriX 400 @ 1600 (Moni)

ISO 1600 (Moni)
TriX 400 @ 1600 (Moni)

Gut, 1600 laufen also. Wie sieht es mit 3200 aus?

ISO 3200 - Steffen
TriX 400 @ 3200 (Steffen)

3200 steffen
TriX 400 @ 3200 (Steffen)

ISO 3200 wird also schon etwas knackiger, aber hat dadurch natürlich auch eine entsprechende Wirkung, der man sich schlecht entziehen kann.

Wollen wir noch eins drauf legen? ISO 6400 - Herrrrrrrrschaften! Der Push über 4 Stufen - ohne Netz und doppelten Boden! Jetzt nur für Sie in dieser Manege! Trommelwirbel… *drrrrrrrr*

ISO 6400 - Alex
T-Max 400 @ 6400 (Alex)

Och, wer sagt's denn. War doch gar nicht so schlimm. Sogar Graustufen haben wir noch einige. Die Hummel fliegt, und das ganz schön hoch.

Salto mortale

An diesem Punkt könnten wir uns nun eigentlich bequem zurück lehnen und den Workshop zum vollen Erfolg deklarieren. Push und Pull in vielen Extremfällen erfolgreich abgeschlossen, kein einziges Bild des gesamten Workshops kam auch nur annähernd schlecht aus der Suppe und es gab für alle Teilnehmer reichlich Erfolgserlebnisse.

Eiiiiigentlich wäre es also hiermit vorbei… wäre da nicht Jürgen gewesen, der - ganz Hummel - meinte, die 4 Stufen Push seien ja wohl Pillepalle und sich auf die ISO 12800 stürzte. Zwölftausendachthundert. Wohl gemerkt mit einem Film, der eigentlich für ISO 400 gemacht ist.

12800a jürgen
T-Max 400 @ 12800 (Jürgen)

Und zu solch einem Ergebnis muss man nun wirklich nicht mehr viele Worte verlieren. Vielleicht auch, weil man etwas sprachlos ist. 5 Blendenstufen, ISO 12800. Ausgeschrieben: ein zweiunddreißigstel des Lichts, das dieser Film eigentlich braucht.

Die Teilnehmer haben ihre kreativen Werkzeugkästchen wieder mit neuen Tools versorgt und wissen nun - nein, sie haben mit eigenen Händen und Augen BEGRIFFEN - dass es außerhalb der gängigen Lehrmeinung noch so einiges gibt, was den Rahmen herrlich (und fast schon subversiv) sprengt und dabei noch richtig glücklich macht.

Leute, wir sind mächtig stolz auf euch!

How's THAT for a constraint?

It's constraint time again.

Brücke

I've lately been in an experimental mood. Experimentation is where I usually cast my caution in the wind and do the things I wouldn't usually do.

Over the weekend, Monika and I held an analog photography workshop here in Tübingen, we were sold out and our group was wonderful! We did a lot of shooting and developments and all was good and fine.


One of the things these workshops do with me is they help me get into that experimental mood and this one was no exception. After the workshop was over on Sunday afternoon, I stayed in the studio to catch up on some office work and tidy up the chemicals and other workshop stuff.

I then decided to take my good old Mamiya 645 with me on my way home. Every sane person would've loaded a roll of TMax 3200 or some similarly sensitive material, but as I said, I was in an experimental mood. So I decided to drop in a roll of Fomapan 100.

Baustelle

As its name suggests, Fomapan 100 is an ISO 100 film. Kinda. I've read somewhere that it is even a bit lower in sensitivity. But that doesn't mean I can't try something weird with it, does it? So I took it to the test, exposing it more in the range of ISO 800 and due to the lack of a light meter I had to wing the exposure, trust my gut.

To add insult to injury, I also didn't have a tripod with me, and it was raining.

With an estimated exposure time of 1 second at f/2.8, the lack of a tripod meant that I had to find places to rest the camera on or against while shooting. Speak of a constraint when it comes to choice of perspective.

Bushaltestelle

But the pictures themselves were just one part of the equation. In the end I also remember quite a few voices that claimed that you can't do a 100 to 800 push with Fomapan 100. What they didn't know is that "you can't do that" is a trigger for me. And it usually evokes the exact opposite reaction from me.

Long story short, I'm extremely pleased with the results. The constraints of using the wrong film, leaving the light meter at home, not having a tripod and having to shoot in the rain allowed (or better: forced) me to take pictures that I wouldn't have taken any other way.

You can see all the pictures here.

What is most remarkable: out of a single roll of 15 shots I liked six (!) pictures enough to post them online. That's a keeper ratio of almost 40 percent. With digital I would've NEVER had a ratio that high.

How about you? Does your choice of medium and the constraints that you shoot under change the percentage of pictures that you like?

Red is the New Black

Black and white film has undergone a lot of changes over the years. One of the bigger changes was making it less blind to certain colors.

Colors
Colors by Chris Marquardt

Yes, less blind. If you look around you, different colored objects will appear to you at different brightnesses, and you might be able to imagine how the scene looks in black and white, simply by translating the brightnesses into grey levels.

And that's how many black and white films work these days. They try to create a black and white picture that reflects the perceived brightness levels that you see with your eyes.

But originally, black and white film would translate colors very differently.

Look at the visual spectrum. It starts right beyond infrared, goes through red, orange, yellow, green, blue to violet and then disappears into ultraviolet. Infrared and ultraviolet are black to our eyes, simply because we don't have the right receptors to see these colors.

Now imagine a black and white film that can see an even narrower range, film that can only see part of the colors. And that's exactly what black and white film did in the old days. It was blind on the red side of the spectrum, so whenever it saw red light, it would register that as black. We call that an orthochromatic film. Only some time after the 1950s did black and white film become more sensitive to other colors. A film that sees the entire visible spectrum is called a panchromatic film.

Here's a snap I took of the same scene, but this time with a digital camera:

IMG 0572 20101016

Compare the two and you will notice that the black and white film is very sensitive on the blue side, but it almost doesn't have any sensitivity on the red side of the spectrum. Blue renders almost identical to yellow, and green is somewhere in the middle grey area. In the early days of black and white photography photographers had to learn how to see in black and white to get to the picture they envisioned, and still today a lot of films have their characteristic look that's at least partially based on how the different wavelengths are rendered on a scale from black to white.

Back in the day, art went so far that during early black and white film productions, the actors had to wear bright and colorful make-up so that a normal looking black and white image could be achieved. Imagine an actor with green lipstick to avoid the lips from going all black on the film. These early film sets must have looked very colorful.
