One of my pro photographer friends made this image. The first person who correctly guesses the technique and the number of exposures will get an autographed copy of his wonderful book ($75 value). It's very heavy. So US shipping only. Sorry.
Good luck to all.
You need to post your answer here.. not on twitter.
This photographer has an amazing and inspiring story, too. He will be revealed on Sunday in my post of the winner. So come back... and see a behind-the-scenes image, too!
When I say inspiring, I truly mean inspiring.
No pros, please.
