Backyard Booty Segment: Natural Progressions from Ryan Flett on Vimeo.
Fstoppers posted this video from Ryan Flett that shows the 2.5D effect — or moving still image effect — in action along with some time-lapse videos. I’ve always enjoyed watching this sort of thing in documentary videos and it’s cool to see them use the same technique outside of a historical context.
If you want to learn how to do this effect, watch this video tutorial here to make the effect in After Effects.
