Sometimes you see a stunning shot and you wonder - how on earth did someone manage to take a shot like that? Well, this site attempts to explain some of the mystery behind shots - by allowing people to share not only their photos, but also details on their shot and how to replicate it. Users can share location (including GPS coordinates), tips, parking and how to get there, time of day,e tc.

Nice idea... hope it catches on.
