Film ISO Rating

[sdgmusic]

HI, I have a 35mm SLR and some old film that i know has been sitting around for a while. I plan to use it as practice film. I know tho that with old film you have to set your SLR to compensate for the fact that the film is old. However, I can't remember which way. if it's 400ISO do I set the camera to 200 or 800?

Thanks
Sean

I wouldn't bother...just shoot it at the rated speed. Color negative & B&W film has enough latitude to make up for a slight shift in sensitivity.

Maybe if you had a case lot of professional film, you could test out some of it and compensate while using the rest of it...but if it's just some consumer film, don't worry about it.
