Praxis, it's all in good fun and there are no winners or losers. It's a great
way to practice your skills, try out new techniques, and get some great ideas.
This is what me and Andy used to do, we would start out with an unedited picture (it
can be a pic of anything you want). Someone would go first and edit the pic anyway
they wanted (as long as something from the original pic is still in the edited version).
Then the next person would take the edited pic and do whatever they wanted (once again
as long as something was reused). You would do this for 2 or 3 rounds.
It's alot of fun and a great way to practice.
