Push Processing: The technique of over developing film to compensate for intentional underexposure by the photographer. Commonly used to gain faster shutter speeds or greater depth of field than normally exposed and processed film will permit.
PUSH PROCESSING - Increasing development time of a film to force an increase in its effective speed, generally done to normalize results when the film has been underexposed. Also known as "Forced development." ...
Push processing
Extending development time, usually to compensate for underexposure caused by a film being upgraded to permit a faster shutter than the light allows.
Digital Push Processing:
Step 1 - Safe Shutter Speed
The concept is simple: When you take the picture, make sure to lock the shutter at a *safe* speed.
This is a REAL ISO 1600 film that gives good results even when underexposed at 3200 with no push processing (so you don't increase the contrast). Results with tungsten lighting and no filter are very good. ¿Grain?
In the example below, the X100 suffered from a rare bout of underexposure, and the white balance was inadvertently set incorrectly too. But redeveloping the associated raw file in-camera using Auto WB and +1EV push processing has given an eminently ...
It is possible to "push process" (underexpose and overdevelop) or "pull process" (overexpose and underdevelop) most color reversal film; however, some sacrifice in quality results in "push processing.
