Probably because of the holiday, the forum seems a little slow, so I thought I'd add a couple of shots I took at the zoo yesterday:
This was taken in the aviary, a place with very poor lighting.
1/800s f/1.8 at 85.0mm iso800 (Canon 85mm f/1.8 USM lens)
I thought I'd use B&W to match the B&W plumage of the pelican:
1/800s f/5.6 at 150.0mm iso100 (Canon 70-300mm f/4-5.6 IS USM lens)
And I thought this shot by the polar bear water tank somehow seemed appropriate in the "Wildlife Rap" forum. This location has outdoor lighting for the water tank, but poor lighting inside the building:
1/3200s f/1.4 at 50.0mm iso640 (Canon 50mm f/1.4 USM)
