Kodak is considered a warm film , reds and yellows
fuji cool film...blues and greens
polaroid, don't bother it will be grainier....
if you know for a fact that you will be shooting all daytime, sunny conditions, 100 is best
if you're shooting all night stuff 800 is best.
my personal preference was 400 that way I only had to deal with one type of film, could stock my bag with a lot of film...and was good to go, whatever I was shooting....
the 800 won't really give you any more noticeable grain if your pictures are properly exposed or slightly over exposed, the grain will come out in underexposed images...
if you want optimum color we could get into the expiration date, and how to buy film based on the date
