I've seen this effect before, where everything is blurred except the front most object in the shot. it was possibly a flash or flex effect which worked in realtime with video and snapshots. can anybody shed some light as to what this effect was called or point to some resources? thanks!
UPDATE: So it was the microsoft lifecam show which had this effect built in and can be seen here at the 2:11 mark: http://www.youtube.com/watch?v=u6ujUJU4Wqw
not as clean as i recall, but that's what i'm looking for. Any ideas how this can be achieved in a custom app?
