What is Depth of Field Preview: how to get it right in camera
What is Depth of Field Preview? It’s an incredibly useful feature found on many DSLRs that allows you to fine tune your depth of field in camera. Here we explain how to make best use of your camera’s Depth of Field Preview feature.
Activate Live View
Your DSLR’s Depth of Field Preview function can be used for viewfinder or Live View shooting, but the larger, brighter Live View image makes it easier to judge what is sharp and what is soft. Here, a wide f/2.8 aperture has been selected.
Press DOF Preview
The Depth of Field Preview control is usually found on the front of the camera, next to the lens mount. Press and hold this button and then rotate the camera’s control dial to cycle through the apertures available on the lens.
Preview and shoot
The image will become very dark when smaller apertures are selected, although the backlit Live View screen makes it easy to see the effect. Once you’re happy with the depth of field, release the DOF preview button and take the shot.
