← Back to context Comment by dylan604 11 hours ago How long of an exposure do you think they would be taking? 1 comment dylan604 Reply jhayward 7 hours ago It's not uncommon for older aerial photos to be single-pixel lines that the film is moved past. The motion of the film is correlated with the motion across the ground, so you can reconstruct a 2nd axis from the exposure.There's no shutter speed, it's continuous.
