PUSH PROCESSING

Push processing allows you to expose the film at higher film-speed numbers for conditions such as low-level light, stop action, or existing light. However, there will be a loss of shadow detail and an increase in graininess.

Because of the film's exposure latitude, you can underexpose by one stop at EI 250 and use normal processing times. Prints will show a slight loss in shadow detail.

You can underexpose by two stops at EI 500 if you increase development time by push processing. Prints will show an increase in contrast and graininess with further loss of shadow detail. However, results should be acceptable for many applications. Expose a test roll to determine the film speed that gives the best results for your application.

You can underexpose the film by three stops (EI 1000) when you use 3-stop push processing in KODAK XTOL Developer. Prints will show an increase in contrast and graininess, and an additional loss of shadow detail. However, results should be acceptable for some applications. Expose some test rolls to determine the film speed that gives the best results for your application.
