To be honest, this was not really shot for this challenge. Took the photo as I put the depicted 20D up for sale. Then noticed the nice textures, as I was processing the image. This is pretty much straight out of the camera (cropped slightly and a little dust removed from the foreground) - I'm loving the 5D more and more!

Sad, but true: not many greens worth on the used market. If I am lucky, I'll perhaps be able to get one sixth or one seventh of what I paid for it in September 2004. If you ask me, it is worth way more, considering its capabilities and output.
