Why do photo finish images look weird?
Bor Gregorcic, Gorazd Planinšič · Physics Education · 2012
This paper deals with effects that appear on photographs of rotating objects when taken by a photo finish camera, a rolling shutter camera or a computer scanner. These effects are very similar to Roget's palisade illusion. A simple quantitative analysis of the images is also provided. The effects are explored using a computer scanner in a way that is also suitable for a student project activity.
