Originally posted by photographyguy74 There is a camera store here where I live (it's only a few blocks away) so I will probably take my film there to be developed. As far as telling the lab to push or pull process and by how much, I wouldn't even be able to tell them that because I do not know what it means,.
I'd recommend just shooting at the box speed to start with.
The basic process of pushing development is that you shoot the film as though it is faster than it actually is, so take a 400asa film and expose like it's 1600asa
Then during the development process it will be left in the developer for a longer time, so the developer reacts more (or whatever it does, i'm not a chemist) to basically bring it up to a normal exposure.
In digital terms it would be similar to if you underexposed each shot by a few stops, then in lightroom (or other software) upped the brightness/contrast until it was correctly exposed.
In both cases you get a correctly exposed image, but at the expense of the "pushing" emphasising things such as grain/noise and contrast.
But, each film acts differently. Some may still look ok at 3200asa, others may just turn into a grainy mess.
