What app to use for high res webcam photo capture? Photo Booth does 640x480. I know the HD webcam on the 2011 MacBook Pros can do better than that. What app can I use for taking full resolution stills?
Kinda roundabout, but you could try this:


Open Quicktime.
Choose File -> New Movie Recording.
On the little down arrow to the right of the record button, choose maximum quality.  Also drag the record button holder to least obtrusive location.
Command-3 to fit to screen.
Take screen shots with command-shift-(3 or 4).
