I saw this beautiful scene driving home from Kirkwood. I just had to pull over and take a shot. Sunsets are particularly hard to photograph. The light is all different colors, so the white-balance setting on your camera can get thrown off, and when a distant subject is, itself, luminescent, (the sky) getting detail in a foreground object is almost impossible. A flash could work if the subject was small enough and close enough (the trees were neither). Fortunately, silhouettes are quite attractive as well.
I took this picture with my Canon S50 on a mini tripod. I opened the sunroof on my (late) Pathfinder and rested the tripod on the roof (a very handy technique). The tripod was necessary because, despite all the extra light, I had to set the shutter-speed to 0.8 seconds.
The moon was just a bonus. (No Photoshop required.)
