An image with great depth of field has all elements from the foreground to the background in focus. A great technique when photographing a landscape image such as this. This image was captured with an f 5.6 aperture, 1/1000 shutter speed, ISO 400, and 35mm focal length. With this particular composition, the distance to the foreground and background was the primary contributing factor to depth of field.
