Uprating (up rated)
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".
Uprating. Shooting film at more than the manufacturer's suggested speed rating, e.g. exposing 400 ISO film as if 800 ISO. The film is then given extra development.

Underexposure: The result of too little exposure in the camera or when making enlargements. It reduces density and contrast.
Uprating: Rating a film at a higher speed index than normal.
