Hyperfocal focusing is a technique that involves manually focusing the lens to the hyperfocal distance. It’s a trick that landscape photographers use to give their photos as much depth of field or front-to-back sharpness as possible.
The old-school advice for shooting landscapes is to focus on one-third of the scene. This is because the depth of field extends about one-third in front of the object you are focusing on, towards the camera, and two-thirds behind it.
If you focus on the closest point in the scene, the depth of field in front of it is essentially wasted and the background may fall beyond the depth of field.
Hyperfocal focusing lets you focus on a specific point, making the foreground and background look sharp. The image may look blurry in the viewfinder when you do this, but that’s because the image is always displayed at the widest or maximum aperture of the lens. Press the camera’s depth of field button to reveal the actual image.
Hyperfocal focusing has its limitations: you’re unlikely to be able to squeeze both the far horizon and something near the front of the lens into the depth of field, for example. But it can be an effective way to increase sharpness at normal shooting distances.
The hyperfocal distance varies depending on the combination of camera, lens focal length, and aperture used. Once these are set, you can work out where to focus using a hyperfocal distance chart or by downloading one of the many hyperfocal distance smartphone apps available.
Of course, to set the hyperfocal distance, you’ll need a lens with a built-in distance scale. If yours doesn’t, you can measure the distance using a tape measure or laser measuring tool, or estimate it using Live View to ensure details remain. net.
