Photographing the Heart of Coaching seminar participants Thursday and Friday posed an interesting challenge: There was a great deal of window light and also some dark areas. On Thursday I used my 24-105 f/4.0 L lens and then shifted to the 70-200 f/2.8 L on Friday. I decided I much prefer the latter, and found it worked well with my fill flash.
The small gallery of the participants can be found at this location.
