I do not totally agree with the "black/white" vision that some folks are saying a deer views the world. The last I read they were also able to interpret some colors as well
I have read on many occasions they see shades of blue and yellow. Whether or not they interpret the colors as blue and yellow as we do, I do not know. They also see ultraviolet as well.
I also think the tree stand shots look excellent especially for not being the 3-D suit.
