1
Check the original capture
Open the photo in Photos and confirm that you are using the original, not a screenshot or a compressed copy from Messages. Check whether the softness affects the whole frame or only a moving subject.
2
Make a controlled edit
Crop only when it helps the subject, then adjust definition and sharpness in small increments. Stop when edges look clearer; halos around hair, text, or high-contrast objects usually mean the edit has gone too far.
3
Use an enhancement workflow
For stronger blur, send the best-quality copy through an image enhancement workflow and compare the output beside the original. Treat reconstructed texture as an estimate, especially around faces, text, and fine patterns.
