I drop off a roll of ISO 400 Ilford XP2 super at the CVS down the street. I was expecting some nice black and whites but instead everything came back with a yellowish greenish tint. Here is my list of possible reasons, tell me what you think 1. The film was expired, but only in January so..... 2. I pushed about 1/3 of the shots at 320, but they all came out the same so I don't think thats it. 3. The 'lab' freaked out when they saw B+W and tried to adjust them. Or.... What do you think?
