Hi everyone! I have a question for film users: Ive been wanting to try a star trails shot for quite a long time, now. My problem? Im clueless. Id like the trails to be quite long, and Id be in a place that wasnt residential (so no outside light influences or very minimal, at least). My camera/equipment is as follows: Nikon FM2 B&W film @ 400 ASA 28mm (highest: f22) 35-135 mm (highest: f22) Which lens would work better? How many hours should I keep the shutter open for? Is f22 still too large of an aperture? Any tips? Should I be going for a lower ASA film? I need TONS of advice, please!
