I visited the Escondido Ecovivarium. This organization is dedicated to rescuing and saving reptiles and snakes... They also use bring these animals to local schools to educate the students. Presently, although their "museum" provides a healthy and comfortable atmosphere for their "guests" it doesn't "look" like the natural habitat. They are in the process of redoing the enclosures to give hem a more natural look...
This fellow was behind a mesh because when he gets excited, he turns red and will possibly bite someone. I shot this with my A6500 and Sony 85mm f/1.8 lens using f/2 to attempt to blow out the mesh...
I uses te 85mm lens again with an f/2 aperture to isolate the lizard's head. BTW... One of the "friendly" dinosaurs in Jurassic park was modeled after thus type of lizard,,,
Again using the 85mm f/1.8 lens but, I stopped down to f/5.6 to get a little wider DOF...
