But if you overexpose it 1 stop then you could just shoot Superia 800 couldn't you? Though some say to shoot Superia 800 at 560 or 400, the same 1/2 to 1 over, but then you could just shoot Superia 400 at box speed... Is any of this stuff really good enough to shoot at box speed without getting flat yucky color and bad grain???
Got no experience with Superia 400, but Superia 1600 *needs* an E.I. of 1000 here and Superia 800 (120 format) can be shot at box speed. So, about the same useable speed, but totally different color palette. 800 tends to saturated color whereas 1600 stays pastel.
