Why it matters.

It helps keep framing and camera position consistent during long exposures or comparisons.

A closer look.

Stable support reduces camera movement. It is useful when a longer shutter time is needed without blurring stationary parts of the scene.

Picture this

Use a supported camera to compare two apertures without changing the viewpoint.

Keep in mind.

A tripod does not immobilise the subject. Follow the equipment manual for stabilisation settings on support.
