Since Pixlr Express
added the History Brush to mobile apps, I've been experimenting with it in different ways. Pixlr Express for the web has had this capability for a long time, but having it added to the phone versions encouraged me to pick it up again on the web version and try some new things.
What I can't stop making with the History Brush, and which you might enjoy trying out, are what I'm calling "illustrated" portraits. You start with a well-composed photograph of a friend or loved one and, by using various overlays in combination with the history brush, you end up with a portrait that places your subject in the foreground with an illustrative background — almost like a comic book in some ways. You're basically creating a very rich, textured background while leaving your subject in real-world focus.
Give this a shot. You might find that what you end up creating is artwork worthy of being printed on canvas and hung on the wall. Come to think of it, it's probably one of the best gifts you could give someone: an artistic portrait that's handmade and extremely creative.
