Place sharpness where the picture needs it.
Focus can be adjusted automatically or manually. A focus point indicates where the camera evaluates the subject; depth of field describes the surrounding range that looks acceptably sharp.
Place three objects at different distances and focus on each in turn. Notice where sharpness moves.
Focus confirmation is not infallible. Magnify an important detail when checking the result.
Follow a connection to understand how these ideas fit together.
The focus distance sets where the acceptable-sharpness range is placed.
Autofocus adjusts lens focus using the selected subject area.
Updating focus can follow a subject whose distance changes.
Wrong focus softens a distance region; motion blur records movement during capture.
This comparison works in both directions.
Focus position and camera movement are different causes of an unsharp image.
