Except for very specific cases, I delete any and all photos where the eyes of my subjects are not sharply focused. If the eyes are not sharp, the image will not work. The image just will not look acceptable so the file gets deleted. An exception may be a unique motion or positional shot, but that does not happen very often.
Today’s cameras focus so much better than earlier models. Since I use “back button focusing” on a routine basis, I have learned that as long as the subject remains at the same distance from the camera, I can set the focus once and forget it. My camera does not “focus search” since pressing the shutter release does not active the focus mechanism. The back button focus process really improved my rate of successful images! Contact me if you want details on back button focusing.
Other than one scenic image shot early this morning, all of my images shared today show eyes that are sharply focused. As you scroll through the pictures, imagine how they would have looked if the eyes were blurry. None of the images would have worked. By the way, eyes with multiple colors that cause the pupil to stand out (bald eagle or rough-legged hawk) are much easier to focus on than dark eyes like the horned lark or lapland longspurs.
