cameraclicker – Thank you. I will take everything you said into consideration. For the third picture, you say you would prefer more DOF to have the whole head in focus. Do you say this because of the shadow? Or do you think the mane (long hair on the neck) is out of focus?
EDIT: The first picture is a candid shot, not a set up one. Still trying to figure out how to set up a photo while photographing horses doing their own thing in the field. A rim light would be very helpful if I was ever to do something like that again.
