I've been looking for. with my flashes were always only one to three "standard films" there. None of these films was to need really for me. Have I resorted to date with the most possible and impossible films of domestic and Bastelstube. This set is endless. One star less for the really scarce size. A millimeter less and it would zip past under or over the film a white streak of light. Scarce as it gets. But with my Nikon SB 900 sparks, as I said just perfect.
