My son-in-law used this film in an Epoque ET100 waterproof (it isn't!!) camera when he went SCUBA diving recently in Malaysia. Notwithstanding = that the brand new camera turns out to be a waste of space/money, the results from the few films which did come out have been very poor with quite a = lot of grain and muddy colours. These were developed by a professional commercial bureau whose results I know from personal experience, to be excellent. How much of the problem is down to the camera and how much = to the film we will never know.
