Made some experiments with UV reflections yesterday, the trees in the windows I found quite fascinating. {} UV differential using D70+UG11xx+old 100mm lens. I had to "sync" the UV and VIS shot, since there was quite some focus shift between UV and VIS. Turned out that the images matched closely after shifting focus closer using the depth of field marks at the lens for f11 - similar to using an "IR" mark on some lenses.
