Hi, next friday I will go in Canada and US for a trip. As a result of the last terroristic events and of the obvious airport restrictions, now is very difficult to travel with film camera... So I have decided to use only one single film, to buy and to develop in Canada and US: Ilford XP2 Super (normally rated at 320 Iso). Anyone has never used the XP2 at 1600 Iso with push processing (how much? +2 or +3?) ? Any example? Thanks very much for your advice! Stefano PS. sorry for my bad english!
