Depth of field 3. The depth of field can be determined by focal length distance to subject the acceptable circle of confusion size and aperture. 1ft 030 m due to the fact that a camera can precisely focus the lens at only one distance at a time sharpness gradually decreases on each side of the focused distance or if you prefer the plane of focus pof. 3 what is depth of field. A smaller sized hole creates a larger depth of field.
We already talked about this so ill recap. The approximate depth of field can be given by. When you bring the focus to 06m the depth of field is now only from 55cm to 68cm. Lower your f stop to get a larger hole which will let more light in.
3 key factors that control depth of field. Another important factor affecting depth of field is the distance between the camera and the subject. For a given circle of confusion c focal length f f number n and distance to subject u. A larger sized hole creates a shallower depth of field.
Changing the distance between the object and the camera. Nikon d300s 105mm f3 16000s iso 200 4700k focus on the eyes of the hoverfly. The shorter that distance the smaller the depth of field.
