Hired a Canon 24mm TS-E 3.5 L for a trip to cuba next week - saw a shot like this a while back (may even have been on this site) and when i saw the challenge i put the lens and idea together and the above is what came out.
I've seen this idea done before, and is very cute! Because of the space between the black-faced post-it and the rest, it gives the feeling that the face is very isolated.
This is absolutely fantastic. Definitely a favorite! :D Great focus point -- it really makes the picture pop! (You should make this into a print! If you do, would you let me know?)
