You can’t truly move focus in post-processing. If detail wasn’t captured at the eye, software can only increase apparent sharpness, not restore real focus.

What you can do is reduce how obvious the miss looks:

• apply selective sharpening to the head/eye area
• slightly blur or soften the tail/foreground so the depth of field appears to sit farther back
• present the image at a smaller display size, where the focus error is less noticeable

Some tools can help with selective sharpening, but pushing them too far often creates an artificial or “cartoon-like” look. So use a light touch.

The result may become more usable, but it usually won’t look as good as a file that was actually focused on the eye. In many cases, this is a judgment call: keep it as a memory, but if critical sharpness matters, it may simply be one to reject and learn from.
