Urbanscreen discovered this strange string-wobble effect when shooting a bass player with a Canon 5D Mark II. No special effects or slow motion were added to the footage — what you see results from the frequency of the strings and the fast shutter speed of the camera. Here’s another video showing the same effect from different angles.
This is super cool, and I really want to try it out. Although, I wonder if it will work with my D90, since it only has 24fps instead of 30fps like the Canon 5D Mark II.
