I did a LO the other day which I feel is a little simple but still pretty. (Please click on it to view credits at my DST gallery.) I made it simple because I honestly was so excited by the effect I created that I wanted to use it right away and didn't have time to do anything more than this.
So then I realized that this might make a pretty cool action... the photo effect, not the LO, lol. :D Click on the action example to view it bigger.
So here is the action for you to download. You'll want to read the Tips for more ideas on how to utilize this action to its utmost.
And remember to give credit and leave a little love below in my comments area. Thanks! :D
