I have a bunch of photos to process, but wanted to share a quick image here from the experience. One of the things I was amazed by (and relished) was spending time in an underground bunker hide right by the edge of a waterhole frequented by hordes of elephants.
This should give you an idea - the image below was photographed at a focal length of 135mm...and is only very slightly cropped for compositional aesthetics, taken with a "full frame" sensor camera.
|Nikon D800 | Nikkor 70-200mm f2.8 VR-II @ 135mm | f8.0 | 1/800 SS | ISO-640|
I will try and share some more images as time permits. Be sure to follow along on my Facebook page or Google+ profile as I share images with more regularity there.
