Depth of Field (DOF)Depth of Field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. One can think of DOF like drawing for the first time. When you first begin to draw your images are usually flat looking, for example drawing a triangle. The triangle is flat, and once you get better at drawing you learn how to make it 3-Dimensional... followed by being able to draw a pyramid with an appearance of a town/mountains/people in the background.
|This photo shows good DOF by having the first person in focus followed by other people/objects in the back, adding depth and significance to the picture.|
The more open your lens is, the more DOF you're going to have.
-F/1.4-F/4 = A lot of light in, focus on 1 thing, a lot of DOF
-F/5-F/12 = Less light in, many things in focus, less DOF
-F/12-F/22 = Little light in, everything in focus (mostly), little DOF
|This photo was taken with prime 50mm at F/2.0. Shooting so wide open allowed for a lot of light to come in and allowed for me to focus on just the one subject (the little girl).|
Below is an example of BAD DOF
|This photo* is an example of bad DOF. Everything is sharp, there appears to be no background other than the clouds, and it looks flat (not 3-Dimensional). |
