A technique in which the suggested film speed is deliberately exceeded, by setting a higher speed on the camera, so causing underexposure, and then balanced by overdevelopment. Also known as "pushing". The opposite, shooting at an ISO rating below that suggested, and underdeveloping, is known as "pulling". (see Pulled , Pushed & ISO)

This is done by changing the film snpeed setting on the camera to a higher ASA / ISO setting than the film actually is. This can be done in reduced light conditions when it is not practical to use flash. The film will be in effect underexposed, this is normally compensated for by push processing. Go to top
