I had the chance to, very slightly mind you, get to know a professional photographer and she was giving out free advise and tips for the taking. One of her suggestions for up and coming photographers was to scour through pictures on the internet, then change them up a bit to your hearts desire. Then you can proceed to use them as the picture on a card you send, as a background for a power point, as a signature on an e-mail or something to that effect. I have done this and although I haven't changed any colors, I have now, at last, found a good background for my blog, as you see. I have this feeling it will stick around for a while.
