The premiss behind PhotoshopContest.com is this: Each day the site moderators will post an image. Designers (and 14 year olds with pirated copies of Photoshop) are then encouraged to download the source image and transform it into something all of their own. You are to then post the image that you have created for the rest of the community to vote and comment upon. You are also welcome to just browse the many amazing creations and cast votes yourself. It really is awesome to see how one image can be seen from hundreds of different perspectives.
This was one of my many attempts on the site. I have had a lot of fun with it over the years. I implore you to participate if you have the means. Send me your username and I will try t save a vote for you. It has been a while since I posted, but when I do, you guys will be the first to know as I will be fishing for votes.
