I have read on here in a passing mention from someone that they shoot the Kodak Portra 800 film at ISO 400, (and have it processed at the normal values... not pull processed). The reason for this was to reduce the grain. I suppose I can see how this would help with the grain, but that sure seems a drastic reduction in the film's ISO. It seems to me this could really cause problems with highlights blowing out. I have searched the forum archives and I think the fellow's name was Russ who shot the film in this way, and had a scan posted of the result. Grain looked non existant in the photo, but then any low res computer monitor view will always look good. I would sure like some more discussion on this technique and if this film and method could be used on an "all around" basis for everything from portraits to landscapes. By the way, I use medium format 120 film. Thanks all.
