Experimenting in the back garden with night exposures, at twilight last night. At this point the available light was halving every six minutes. The top image was 6 secs at f/22, the second one was 13 secs, and one that didn't make the cut (6 minutes later) was 30 secs.
Having narrowed the field from about six images that included these trees, down to two, I couldn't actually decide which of these two I preferred. Which do you prefer?
