A funny thing happened during the rehearsal of Hello Dolly last night: The spotlight failed. Even though I’ve never been a boy scout, I was prepared.
While the spot light was working, I used the 17-55 f/2.8 lens from the front row of the theater. In this case, I shot at f/4, 1/160, ISO 2000.
After the spotlight blew, I switched to my 35mm f/2.0 lens and used my feet to zoom. This image required f/2.5 at ISO 3200 and 1/160. I'm not comfortable shooting most of my lenses wide open in a high contrast theater environment. The faster, fixed focal length lenses let me stop down and still catch a little more light than my "fast" zooms. At ISO 3200, I had to use Noise Ninja in post-processing, but actors and actresses usually appreciate the loss of sharpness that comes with noise reduction.
