How to Develop Film That Has Been Pushed

Push processing film is a way to make up for underexposure in film while taking photographs by overexposing the film during the development process. It̵7;s useful if you set your film speed to the wrong value or if you took pictures at a higher film speed than the ISO of the film in your camera, also called pushing the film. In order to correct the underexposure of the pushed film, you can push process the film.
