The book I am illustrating now with designer LeAnna has given up the opportunity to be especially creative. I applied some filters to some of the background pattern art and LeAnna loved the look. I purchased this filter program Mr. Retro when I was designing scrap booking papers.(You can test drive the applied filters on their website) You can see above on the first piece I have a filter applied and the bottom is the original paint job. I think I applied "vintage tee" to the image on the left and on the top right is the"thrift" filter. On the bottom I applied the rust filter to the entire piece. You can certainly get much more creative than these samples but it sure is a fun addition to your Photoshop program. I tend to like my work on the fresh side but this can add a new look to a piece-and it is always fun to play!
