The "push" was to simply extract more contrast out of the neg. most of which tend to be too low in contrast to aid in machine printing. But generally while pushing e6 slide films is very viable pushing c41 films is generally ill advised. Often resulting in color crossovers. And not really resulting in any real speed increase which is measured by the film speed you'd use to achieve full shadow detail. This photo which ran a week ago strikes me as being under exposed a good full two stops. But represents an type of image which is almost viable anyway done this way. How many viable images Didier was above to pull out of a typical roll of generally subject I'd like to see. I'd think few. I also disagree with his classifying such photography as low light photography. Cameras with out good center weighted or spot meters will be fooled by such performance subjects into over exposing the heck out of the subject itself which has quite a bit of light on it and is generally shot hand held with no problem with short to longish teles with ample shutter speeds (125th) and not ultra fast films. 400 I'm sure being the norm. A basic rule of c41 is just make sure it gets enough exposure. Unfortunately development does not much affect this like is often would with slide films designed for this and sometimes but not often does in black and white. When monochrome Chromegic films first came out from Ilford and Agfa they hyped the idea that film speed was wildly variable. Pick your ASA! This turned out to be in no way true. And they stopped hyping that fantasy after awhile. As there is no reason certainly that it would be more true with monochrome c41 than it would be with full color 41 film. But it's been planted in our collective unconscious as a civilization. Mark Rabiner Photography Portland Oregon http://rabinergroup.com/
