Aperture and Depth of Field


Aperture and Depth of Field

Larger aperture openings, like f/4, will tend to have shallow depth of field and a smaller aperture opening, like f/16, will tend to have everything in focus. Depth of field is doubled by closing down the lens two stops.

The size of the stop is one factor that affects depth of field. Smaller apertures (larger f numbers) produce a large depth of field, allowing objects at a wide range of distances to all be in focus at the same time.

Decreasing the aperture opening increases the depth of field, which describes the extent to which subject matter lying closer than or farther from the actual plane of focus appears to be in focus. In general, the bigger the aperture (smaller f numbers), the shallower the depth of field.
