I agree with f16 aperture but not the 100 speed film. I've used 400 speed print film in the past with really good results. Also, and though it's tricky, a 2-3 second exposure is ideal. After that reciprocity failure creeps in and your color shifts plus the blacks go all milky.
Instead of a polarizer, try a filter for shooting in fluorescent light...it helps correct the color shift on longer exposures. -Brendan MacRae --- [EMAIL PROTECTED] wrote: > You are not trying to set exposeure for the dark > sky; you are exposing the lightning itself.
