    So, I have a Canon EOS Rebel 2000, and on it is an ISO setting, ranging from . Now, I use Ilford 100ISO B&W film. Out of curiosity, what would happen if I were to change the ISO setting to anything other than 100? If I were to set it to, say, 400, would I be able to shoot it as if it were ISO 400 film, but then develop it longer in the darkroom afterwards, or...?

    I guess it boils down to is what happens when the ISO setting on the camera is different than the film used.

    Cheers :)

    *smacks forehead* sorry about that

    so basically, i can push the film (to a certain extent) higher than its rating, but then develop it longer later at 20-25%/ISO rating (from 100 to 200, etc?), and it's more contrast-y?

    Sorry man...I guess I'll just take this to that thread hah

    Great minds ;)

    Anyway, that's pretty much it. Most of the development charts have information for pushing from 400 to 1600, I haven't seen to much on pushing from a lower ISO film.

    Just remember that if you change the ISO to push/pull the film, then you will have to develop the entire roll like that. You can't change in the middle of it.
