Learn to wait for expression, which I feel comes with eye contact. Watching and waiting for that movement takes patience. I’ve photographed the baboon named ‘One’ at the Phoenix Zoo on many occasions. Sometimes spending an hour or more with fruitless results. The image above shows how patience can pay off with ‘One’ in soft light and looking as if he could see into my very being.
All creatures look more alive with a catch light in the eyes. The smallest movement of the head or a slight change in position in relation to your prey makes the difference. Look for theses small changes when practicing to be aware when you get to the wild.
