I recently upgraded my monitors and needed a background that was big enough to cover a 23 inch screen. My wife and I often take walks in the afternoon to the lake near our home and I usually take my camera with me. We got to the lake just as the sun was setting behind some clouds and I managed to get this shot before it disappeared.
If you would like to have one for your screen click here. I simply ask that you use it for personal or non-profit purposes and give credit to me for the picture if you post it anywhere.
