ISO Film vs. ISO Setting

[GoM]

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

Check out my thread about pushing film (it's the only right below this, right now).

*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.
