Jostein, I've noticed this same lack of sharpness in my own nighttime images where the exposure lasts several hours. Trees, hills and mountains have a very soft look to them. Photos of the same scene in the morning with the same lens, film and camera are nice and sharp. I have two theories as to why this is in my case:
1) How the lens is focused at night: it's just racked out to infinity, since I can't see anything through the viewfinder. 2) Color negative film (and maybe any film) loses acutance at longer exposures. t On 11/18/02 11:16 AM, Jostein wrote: > There is one thing that strikes me about the focus in these shots. > Presumably in focus, they seem blurred.
