Porta is very expensive film. I think I'm going to buy a lot of Supra Xtra 800 and see if I can get it a stop or more. That stuff sells for ~$3-4 a roll.
Superia Xtra 800 is beautiful film and I like it much better than Pro 400H. Optical enlargements from 35mm to 5x7" are grain free with Portra 400 but borderline with Superia Xtra 800, so use it when you need the speed.
Trying to be the best of whatever I am, even if what I am is no good.
