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. It's especially evident in Chet's photo when compared to the same scene by daylight. I don't doubt the eyesight of you guys, and I don't suspect you to have flimsy tripods either. so I suppose there must be something technical... Is it just a scanning matter, a matter of large apertures, or is it something more peculiar? The first thing I thought of apart from scanning, was that resiprocity failure had something to do with contrast rendering, but it shouldn't be that serious, even at 1.5 minutes exposure. Any suggestions? (Including me imagining things?)
