We humans pay a lot of attention to eyes, so if they’re blurred it often detracts from our pictures. In the shot of the Red-legged Pademelon shown above, most of the animal is out of focus, but because the eyes are sharp it doesn’t matter.
Even macro photography can benefit from getting a critter’s eyes in focus.
And what do you do if one eye is further away than the other? Just focus on whichever eye is closest.
