By adjusting the f-stop, the photographer controls the depth of field. Smaller f-stop value = larger aperture diameter = smaller DOF; Larger f-stop value = smaller aperture diameter = larger DOF; The following examples show small or shallow depth of field vs large or deep depth of field. Depth of Field: The distance between the closest and furthest points in an image that are in 'acceptable focus'. Narrow (or shallow, or small) Depth of Field: To have a shorter depth of Matt Crawford 0 Depth of field is more than just a side effect of using a wide aperture. It can be used to creatively blur the background and create focus on foreground subjects, or it can be used to make objects in the foreground stand out by blurring everything behind them. Deep Depth Of Field Examples. One way that photographers can create a sense of depth in their images is by using a deep depth of field. This technique, typically used for landscape or architectural photos, blurs the foreground and background to give the viewer an idea that there is more than what meets the eye. Focal length. A short focal length (or wide-angle lens) will usually have a deeper depth of field. And a longer focal length, like a telephoto lens, will often have a more shallow depth of field. You can see below as the lens gets longer, the image around the subject gets blurrier. iVup.
