Colorful Umbrella Parade
...at The Bund. OK...I've stolen the idea from Chinese photo artists selling their color key photos for much money in various markets. This one here is authentic by me ;) And the umbrella colors are just the genuine colors of the umbrellas used. All quite OK, except for the black one on the right...would have loved that one to be a dark yellow.
Done with Aperture's fantastic Brush Away functionality with Edge Detection.
