How to get a Large Depth of Field


Like we discussed on the small depth of field page, depth of field is defined as the zone of sharpness in a photograph. With a small aperture opening, or large f-stop number, the zone is much smaller, and creates the types of images with an up-close, in-focus subject and blurred background.

To achieve a large depth of field, simply reverse the steps taken to create to achieve a small depth of field. Open your aperture wide, and use a small f-stop number, such as f/1.4.

Large depth of field works with subjects that are a far distance away, such as landscapes. Unlike large f-stop numbers, that create a shallow depth of field, small f-stop numbers create sharpness in the entire image.
