Understanding Depth of Field in Photography

The range of distance within the subject that is acceptably sharp is called the depth of field. This technique often depends on the camera. The factors that usually affect the outcome of a depth of field technique are focal length of the lens, distance of the camera to the subject, and aperture size.
Focal length of the lens. The focal length of the lens is inversely proportional to the depth of field, meaning, the greater you want the depth of field, the smaller your focal length number (number of the lens) should be. An example us using a 28mm lens that has the ability to capture more of the picture in sharp focus than a 100mm lens.
Distance of the camera to the subject. This time, you should take note that the depth of field is directly proportional to distance, meaning, a subject with a greater distance to the camera, the greater depth of field you’ll have (than an extremely close-up or close-up subject) Hence, a depth of field shot has distant subjects that are out of focus.
Aperture size. Adjust the aperture setting if you want to have a foreground or background while having the subject in focus. The wider the aperture, the shallower is the depth of field.
