Hello.

I'm planning to shoot some Tri-X Pan 320 4x5 sheets and am wondering at which iso to shoot it. Is it best to shoot it at 320, faster, slower? or is it a matter of taste.

I've heard that for color print film you're best over exposing 1/3 stop since you'll get more color.

W/ BW, is there any advantage to shooting at a different ISO than rated (unless of course you want to push the film).

Thank you!

Sal
