Shooting At Night Is Hard! Part 2

In my previous post, I stated that focusing on a subject at night is very difficult, but I managed to get a more or less clear shot of my buddy Brian. How did I do it? 1. Stabilized my camera on a tripod. 2. Had Brian shine a flashlight on his face. 3. Autofocused on his face. 4. Switched focus to manual, so the lens did not refocus when I pressed the shutter release. 5. Asked Brian to turn off the flashlight and hold very still. 6. Snapped off a shot and examined the LCD. If something was off (focus, composition, and/or exposure), repeat the process. After what must have been an hour, I finally got the shot above. It was hard work for the both of us! By the way, there is a hot shoe flash shot through an umbrella positioned above and in front of (camera left) Brian's face. Here's what it looked like when Brian pointed his flashlight directly at his face:
