The rules of Photoshop Tennis are simple- Add a little contribution to the image using photoshop (or any photo editing program), until it's decided to change images. Doesn't matter your skill level at photoshop, it's not really meant to be taken seriously
1. I'll post a decent sized image
2. The next user reserves a spot by posting with "reserved" or something similar.
3. They will have about an hour (or until someone notices) to add something to the image.
4. Make a new post (so it updates the thread) with your version of the image, and delete your reserved post. The next user will reserve the spot to add to the image
...I'm horrible at explaining stuff like this, so I hope that makes sense. If not I'll give you an example
Let's say I started this thread with this image
Whoever reserves the spot would save the picture, open it in photoshop, add their own little contribution
then submit it in this thread, and the next person that reserves, adds the next contribution
and so on and so forth...
I'll start it with this image, and hope that at least a few RAWK'ers might enjoy this
