50D...Sunset at 1600ISO
Here's four pic's shot in order. (priority mode) Constant iso, changing shutter speed, aperture and focal length. The sun is ready to disappear behind a wall of clouds. Even though I post processed all pic's the same way... the sun, exposure gave each picture a different look. I used my 100-400mmIS.
