Camera Effect of the Day: Photographer Jason Mullins demonstrates the so-called “rolling shutter” effect using his iPhone 4 to photograph blades of an airplane propeller.
Mullins says:
For those who want to try this out, just point your simple electronic shutter camera at an object moving parallel to you, preferably fast, and take the photo. The faster the relative speed between you, the more the distortion. Rotating objects go really weird!
