live butterfly exhibit

This was a live butterfly exhibit at the Academy of Natural Sciences in

Philadelphia.

The exhibit area was 85 degrees F @ 80% RH. Coming in from the

cold it took about an hour for the camera and lens to reach equilibrium

with the ambient conditions of the exhibit to remove and prevent the

buildup of condensation on the equipment.

I set the camera on manual exposure 1/60 for handholding and f11 for

depth of field. This resulted in ambient light underexposure so I used a

right flash dialed down 1.5 stops for the primary light source.

Please, your constructive critiques are greatly valued.
