05/24/06: What is "racking?"

Pro Photo Tip: What is racking? How do I fix it?

Racking is a term pros use that refers to situations where an auto-focus camera cannot focus -- either due to low light or zero contrast in the subject. You can experience this by pointing your auto-focus camera at a clear blue sky (NOT at the sun, mind you!). The camera will not be able to find a focus point and will "rack" in and out to try to find a focus point.

Rack focus is a cinematography term that refers to a shot that starts with one object / subject in sharp focus and then the focus point is moved to another object / subject.
