My personal rule is to keep all photos except for the following:
- Accidental shot of the floor or the inside of my camera bag
- Flash misfire where the image is completely black
- The subject is blinking or making an unflattering face
- Major motion blur
- The image portrays the subject badly
This is my general rule based on being an author and an educator. I sometimes need an example of a bad or blurry photo to teach how software or a photography tip can help fix it. You should create your own set of rules as a guideline. Don’t be afraid to break your own rules when you see a bad image you love and wish you had the ability to make it look good.
