i just developed some iso 400 b&w and WHAO is it grainy, i thought at first that its because i messed up the chemistry but i was looking at a developed version of iso 400 color film that i didnt develop and its very very grainy as well. On my dslr at iso 400 there are very very few specs of grain but on film its crazy how much grain there is. So is iso 400 normally really grainy compared to iso 400 on a dslr? also would iso 100 be ALOT less grainy? because on dslr going from 200 (thats the neutral setting on my d5000) to 400 is not much of a difference.
