Hi, What would be a recommended film for night photography, say with shutter speeds from a few seconds max, maybe 5 seconds exposure most. I tried the Delta 400 (120) @3200 and developed in X-tol, it was OK, but maybe there is a b/w film out there that gives better results when doing night photography. Or I can shoot the Delta 400 @800 and increase exposure times. Anybody? Thanks.
