Ed, I agree with Pete. Also, you must take the statement that XP-2 can be exposed at a wide range of speeds, with a bit of a grain of salt. In my opinion it has, like all color negative films, a pretty good exposure latitude. However, I think it works best when overexposed a bit. Underexposure with XP-2 doesn't do much for me. If you need to underexpose and push develop, I think you are better off with a regular b&w film.(posted 8333 days ago)chris
