Another view of Mr. Tootie, looking straight into my eyes that lets me know he is clearly in charge.
Chimpanzees are often located on the forest floor amid dense vegetation. Wtih the overhead trees allowing very little sunlight penetration, this is all about low light shooting which calls for a camera with low noise at high ISOs. My first camera of choice is the Nikon D5, sporting a sensor that has some of the lowest noise levels in the industry with operating at high ISO levels.
The image below was processed in LR with NO noise reduction.
Shooting details: Nikon D5, Nikon j70-200mm f/2.8 @ 82mm, ISO 3200, 1/60 sec @ f/3.5.
