Picture of my good friend in my backyard one fall afternoon. I took it with a Canon Rebel XT (don't remember the settings, sorry), then migrated it into Photoshop. I did some retouching with the Spot Healing Brush and Blur Tool, then applied a custom gradient layer above it, setting the opacity at vivid (I think). Made a group of swirls as well, adjusted opacity and threw a Gaussian blur on there too.
Man, I love rainbow colors!
