OK. What are you intending to take pictures of? As you well know, 400 ASA is good for moving targets. Night photography I would suggest 400 perhaps 200. BUT I gather you want a low grain NAD a lot of color how about 200 then. it's not that grainy. If you really and to go for the gusto there is the film which is used for holograms. I think it's got a ASA rating of 0 - 5 or something like that! How about if you use slide film. It's designed to be blown up and it had plenty of color. I would suggest Fuji Sensia. You can develop it at home if you really want to. Since there are slide developing kits available where you don't have to deal with constant water baths. Bsteph
