Someone recently posted a sharp, 14-second-exosure photo of a friend standing outside, which astonished me and led me to make a few experiments yesterday. I had to use myself as a model, so my getting up and down probably have contributed to motion blur in some frames. In any case, I found 2 seconds to be fairly reliable, 4 to be uneven, with some clearly blurred (if I may use the oxymoron) from motion and others probably usably sharp. I'm just looking at 645 negs with an 8x loupe.
Naturally, the degree of support in the pose makes a difference. I tried both supported and non-supported standing, and sitting with and without a hand to the face at a table, in a backed chair, on a padded bench.
Anyone have experience to share?
