How long of an exposure do you think they would be taking?

    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.
