Shallow Depth of Field

Capturing an image with a shallow depth of field is accomplished by using a large aperture (f/1 – f/11). This means that only small amounts of an image will be in focus. It can be a little confusing because you have a small number for a large aperture, but what helps me remember is “a small number (f-stop) = a small amount in focus.” Any f-stop f/16 and up will keep more of the image in focus. The images below demonstrate shallow depths of field. Notice that the subject, or only part of the image, is in focus, while the rest is blurry.

Grazing: 1/23/18; 5 pm; near Monkey Rock; 300 mm; f/5.6; 1/320; Canon 80D
Fencing: 1/23/18; 5 pm; near Monkey Rock; 100 mm; f/5.6; 1/200; Canon 80D

Deep Depth of Field

In contrast to shallow depth of field, where only part of the image is in focus, a deep depth of field will have everything in focus. This is ideal for landscape photography. To accomplish this, you close the aperture, so it is very small (f/16 – f/32+). Again to help me remember, “a large number (f-stop) = a large amount in focus.” The following images are example of this.

Country Skyline: 1/29/18; 5pm; Rexburg; 18 mm; f/22; 1/5; Canon 80D, Tripod
Tracks: 1/29/18; 5 pm; Rexburg; 22 mm; f/22; 1/5; Canon 80D, Tripod

This image was not as sharp as I would have liked, but you can tell that most of the image is in focus, and it still turned out mostly decent.

  1. Megan, I really enjoyed your description about what the difference between the shallow and deep depth of fields were at the beginning a very concise clear way to put it. I like your image of the fence, it really shows that shallow depth of field, very a beautiful image.
