I shot these bikes at Eastern Creek during the A1GP, but was using a pretty long zoom and while the bikes were more or less in focus, I felt there was no separation of subject and background.

I selected the bikes and put them into a different layer, and Gaussian-blurred the rest... but wasn't sure whether it was enough?

Decided to crop the picture, and selectively desaturate as well.

Not sure whether it was worth the effort, but anyway C&C welcome!
