Push Processing or: Give me more!

18

No ISO 400 film at hand but facing a nice low-light situation? Your frigde is full with ISO 100 films but you want to shoot fast moving things? You want high contrast and hues shifts without crossing? Maybe Push Processing is a way!

All pictures Lomo LC-A. Indoor shots with drugstore ISO 100 film pushed to ISO 400, outdoor and summer shots with Agfa Vista 200 pushed to ISO 400.

Push Processing is an old known darkroom technique. Basically it´s about underexposing and then overdeveloping a film. Just put a ISO 200 film into your camera and set it to ISO 400. Expose the whole film with this setting and upon letting it developed write “Please push one step” on the envelope. I wanted to try this for quite some time and now that I did, I’m stunned by the outcome: high contrast, some hue shifts and large grain.

It’s also possible to push by more than one step, I already tried a ISO 100 Film on ISO 400 setting and it turned out good. Pushing ISO 400 to ISO 1600 should be worth a try. Black and white film can be pushed even more.

Push processing should be tested in combination with X-pro and Redscale. There’s a lot to do! Try it out!

    Great tipster and gallery!! That's a good old technique which gives more texture and contrast to the shots... with b&w, I remember that the Ilford HP5 400 asa is very very flexible and can be shot (and developped) as a 800/1600 or even 3200 asa film... the more you push, the more grainy are the shots and sometimes this gives a fantastic dramatic vintage mood....

    My sister (a professional photographer) had suggested this to me, but I'd never seen examples till now... great gallery!

    i shoot the film underexposed, then say to the developer push one step higher, is that it? i sometimes love underexposed shots... :-)

    Nice ! For other push-processing experiments, you can visit @rater, @eggzakly and @stouf 8DDD

    it depends on a film: some can be pushed, others might become completely abstract. pushing a slide/xpro film is even a more sensitive process where perfect temperatures can make wonders (read: find a trustworthy lab). and finally, some films are especially developed for pushing :)

    iv always been curious about this technique. thanks to ur experiment i dont have to worry about a low stock of iso400 film in my place

    OMG! I did this unknowingly -- exposed an iso 100 with iso 400. I begged the lab to do something about my underexposed roll and was surprised with the result. Came out really nice! Now I feel less stupid knowing there's a name for my mistake. Great tip! Thanks!

    I often do it with B&W I shoot. I will take a roll of 400 and set my ISO to 800 on my camera and shoot away. When I take to lab I ask them to push to 800. I will usually mark the film can with 800 so I don't get mixed up with the other film shot at regular speeds.

    Wie formuliert man diesen Wunsch denn am besten auf Deutsch?

    is it possible to overexpose a film and then do the opposite of pushing?

    good inspiration for pushing film. thanks!

    @daforl: yes. that's called "pulling"

    Has anyone ever pushed a lomo colour 400 film to 3200? Just trying it out but feel like it's a waste of time since I'm on a short holiday.
