Camera Glossary

A technique of combining multiple images taken at different focus distances to achieve greater depth of field.

Detailed Explanation

Focus stacking is an advanced technique used primarily in macro and landscape photography to achieve maximum depth of field. Multiple images are taken at slightly different focus points, then combined in post-processing software. This creates a final image with greater apparent depth of field than possible in a single shot. The technique is particularly useful in macro photography where depth of field is extremely limited, or in landscape photography where both foreground and background sharpness is crucial.
