Push processing
A term from Photography, referring to how photo-sensitive photographic film is processed to show a latent image (film developing). In this case, Push Processing means to process so that the film responds as if it were more sensitive than originally indicated by the manufacturer. Using this type of processing will allow the film to be used under lighting conditions that would ordinarily be too low for good exposures. However, typically some noticeable loss of image quality (e.g. higher contrast, lower resolution, distorted colors, objectionable grain, etc.) will result from this technique.
A complimentary process, Pull Processing, refers to processing a film so as to be less sensitive than indicated by the manufacturer.
