I think we should take it in turns to upload a single unedited photograph, RAW if possible. Then we all edit that photograph to our own taste and share it a week later along with our editing process, then take some time to comment/critique. The benefit of this is that we're all working on the same base.
Alternatively, we could choose a theme and take/edit our own photographs to suit that theme. The theme could either be in the shot (landscape) or in the editing (b&w).
Already did a crappy photoshop of this one a while back and I started a few days ago on a new version.
Old quick n dirty photoshop :
Will post the new one when its finished (but it is more true to the original so far). Of course the sky is over done, but the original is a bit lighter than it was in reality.
I do have a few more, but this was my best shot of the summer :/
