[Push +3] This shot was in very low light and pushing 3 stops allowed us to shoot at a faster ISO speed to freeze the action with out camera shake.

TMax 400 pushed 3 stops to 3200.

Pushing 3 stops it the most we recommend and unless you like very contrasty and grainy photos you should only do so if necessary.

Example of Pushing Film 2 Stops


The pushing or pulling process involves shooting and developing film at a different ISO then what the film is rated for. Let’s say you want to push your 400 ISO film 1 stop (+1), set your camera to 800 ISO and shoot/meter the whole roll as 800 ISO. When the roll is finished, clearly mark the speed on the film canister. Marking the canisters is for your reference in completing the order form and letting the photo lab know how to adjust development time.
