I played with the hue (made it more green/cyan instead of magenta/yellow) then desaturated it. Plain black and white just doesn't suit my mood today!

Here's a picture of musicians Tegan and Sara. I borrowed it from Google to play around with.
This is the original.

I found a "retro color" tutorial, and I played around and made it look liiiiiike this!

This one, I cut Sara out using the pen tool.

This was a picture I found on flickr (the background), and I used the quick mask tool to cut a bug out of one of my own pictures, and paste it in!
