no flash no tripod allowed

We went to Flagstaff yesterday first going to the Arboretum and then because we figured we had
plenty of time, we checked out the Museum of Northern Arizona. As it turned out, we lucked into
being there on the last day of an exhibit of a mystery Sickle-Claw Dinosaur called Therizinosaur.

Tripods and flash are not allowed in the Museum so I decided to experiment with high ISO. Always impressive!
Even at ISO 2500, noise was more than acceptable. We only had a few minutes with the Therizinosaur but
the exhibit is moving to Mesa’s Arizona Museum of Natural History so I hope to go for some detail shots.

NOTE: All images were shot in the RAW format which allowed for recovery of highlight and shadows.
I also used Topaz Adjust to increase contrast.
