Camera shake is camera movement during capture that can blur the image.
Distinguish an unsteady camera from a moving subject.
Long shutter times and tight magnification make shake easier to see. Better support, a shorter exposure or suitable stabilisation can reduce it.
Photograph a stationary object handheld and from a stable support at the same slow shutter setting.
Keeping the camera steady does not stop subject movement or correct an incorrectly focused lens.
Follow a connection to understand how these ideas fit together.
Shorter shutter times leave less time for hand movement to blur a frame.
Conditions: Handholding technique and image magnification remain comparable.
Focus position and camera movement are different causes of an unsharp image.
This comparison works in both directions.
Tight framing makes small camera movement easier to notice.
A subject can move with a steady camera; a camera can move with a stationary subject.
This comparison works in both directions.
Stabilisation counters some unintended camera movement.
A stable support reduces camera movement during capture.
Compare a handheld frame with a supported one to isolate camera movement.
