Wildlife Photography – Basic Rule Number 5 – Learn how to over- and under-expose with your camera!
Your camera is smart, but not smart enough. Once you have your standard settings only concentrate on one adjustment while you are shooting. If the object you are interested in is much darker than the surrounding you have to over-expose. If the object is much lighter, you will need to under-expose. This takes training; so get out there, make some exposure mistakes and learn from them.
