Can anybody out there in cyberspace advise me on the differences between the current ultra high-speed films? How are they for grain? What are the effective speeds? Any development recommendations?(posted 9050 days ago)I work as a photographer and lab technician, and have for more than 20 years, so I am definetly not a beginner. My current favorite film is Ilford HP5+ (35mm), which for me has a limit of about EI 1600 or so. I need a film I can use to photograph my grandkiddies falling asleep in their mother's arms!
