Many of the night pictures on this page used a technique called layer compositing. Because of the extreme range of subject brightness, capturing detail in both shadow and highlight areas on a single frame is impossible. Therefore, I used a tripod and made two (sometimes three) separate exposures, then later combined the most appropriately exposed section of each exposure into a single frame. The result is an image that retains detail in dark and bright areas, for example foliage (dark) and Capitol dome (light).

The Washington Monument:
The White House. The second picture is detail from the rooftop - who is the sniper aiming at?
Field note: This shot was handheld. I was prevented from using my tripod at this location by a rather burly man in an official-looking uniform. National security, you see. "But sir, don't you realize that by forcing me to take a blurry picture, you're letting the terrorists win?!"
