what an amazing experience you've had hix. Your trip report or journal with pictures is excellent. 500 photos? I hope you remembered to put the camera down and just looked at them. Thanks again for sharing this with us.
Beginning an obsessive photographer and having seen things only through a lens on occasion I chose to go with minimal camera equipment on this day partly to make myself do just that. I got a few decent pics with my 28-75 lens and tiny old ixus but made myself spend 98% of the time experiencing it. Same with the chimps, I had full camera gear but thought "stop taking photos and just LOOK"
