Sometimes it’s after the sun has disappeared below the horizon than things become really interesting. One thing that can be anticipated is that the light which remains will be very cool and thus quite blue. Exposures will be quite long as a relative matter; but as long as you can achieve a meter reading in the range you desire, you can always be creative. At Cowee Mountains Overlook recently the late light had been spectacular with the clouds and fog rolling in and then rolling out. The sunset had been interesting enough even with the clouds that had obscured the sun as it set. After the sun disappeared the wind calmed to a whisper and the mists began settling in the valleys below. “Thinking” like a telephoto lens I reached out into the lines and triangles created by the narrowed field of view and picked out a selection of them where the fog was thin enough to be seen through, more so than less. A focal length of 157mm gave me the angle of view I was looking for. At f/18 I had enough depth-of-field, and a shutter speed of 30 seconds at ISO 100 gave me a medium overall exposure with no loss of highlights which I could then darken in post-processing to return the tonality closer to what I had experienced.
