Hi, I am supposed to photograph my friend's beach party in two weeks. I am planning on using a Ricoh GR1v (28mm) for this. I've had good results before with this camera photographing events. The only problem I have with this camera is that it only goes to 1/500th sec shutter speed. I assume midday on the beach with sand reflecting sunlight this will really limit what films I can use. 30.5 mm filters are hard to find. Any suggestions on what film I should use for this?
