"Charlie" is a famous consultant who is widely loved and admired. Along with this shot I took several hundred pictures of the OD Network Conference in Seattle this past week (see http://www.pbase.com/odnetwork/seattle09) which were put up on the jumbo screens as participants came into the large plenary sessions.
I had a good workflow down and did all my processing in Camera Raw ... not touching Photoshop itself. Getting a good color balance and crop were my main goals. Fun work that kept me going day and night.
I mostly used my 24 to 105 lens but also in some situations used my f/2.8 70-200 lens. I did some available light work, mostly at very high ISO settings, but most shots were bounce or direct flash.
