This is a picture of the Denver skyline, and I took this shot tonight using the built-in HDR feature in the Canon 5D Mark III. I usually use daylight white balance for twilight photography, but as it got darker and the sky was almost black, I noticed that the colors in the image seemed too yellowish for my taste. So I switched to tungsten white balance and that made the difference. The HDR capabilit of the camera combines the five exposures that comprise this composite and assembles them in-camera as a final jpeg image. It's pretty impressive.
My settings for this picture were: f/6.3, 200 ISO, and a 70-200mm lens. The shutter speed varied per the bracketed exposures.
