I'm constantly amazed with what actually sells here at dreamstime and sells very well for that matter. One such subject is the humble feather. CAN YOU BELIEVE IT? I certainly can't understand what it could advertise but the amount of sales the subject has wouldn't you want one of your own? I thought you would. Just follow this simple photoshop tutorial and with a little imagination on your part you could be coming up with something like these.
Good luck and enjoy
