Hyperfocus

Hyperfocus is nothing more than using the acceptable field of sharpness in order to create an image that appear sharp over a long depth. This is critical when taking landscape. Yet it can be used in any type of photography.

Hyper focus depends on the lens, the aperture setting and the focusing distance. In short, you need to know your lens in order to achieve the best result.

► Depending on your lens length the DoF created is different (longer in wide angles and shorter in telephotos).
► The aperture should be set at or near the best lens f-stop to create the sharpest capture.
► The focusing plane distance is critical.
 ○ It should be somewhere before the foreground and the background. The acceptable field of sharpness length is your guide.
 ○ It should begin with the foreground point of interest and end with the background needed at the limit of the acceptable field of sharpness.

Using a narrow aperture like f22 or above is not a good idea as the small aperture will soften the image. It is better to go down to f11 or f16. Experiment with your lens in order to learn what aperture gives you the best results.
