I can attest to the sleeping qualities of the tundra.
In general, I avoid photographing wildlife from a downward angle, and unless obstructions such as tall grass are present, you will often find me photographing wildlife from a squatted or seated position.
However, when the subject is lying down on the ground, it can be especially challenging to get down to their level.
In this case, I was flat out, lying down on the tundra alongside this huge bull moose.
With the tundra under me, I have seldom had such a comfortable shooting position — a very welcomed restful position after hiking the miles necessary to get to this location.
Shooting handheld, taking advantage of the excellent image stabilization this camera and lens provide, gave me the ability to get into unique positions very quickly on this adventure.
