In this tutorial, we will learn how to adjust the depth of field on a camera
What is the depth of field?
The depth of field is the distributed area in front and behind the point where you focus. It is also called the area of sharpness. In a photo, it basically corresponds to the distance that appears clear. Everything before and after this part will gradually appear blurred, so the depth of field will always be one third in front of the focal point and two thirds behind the focal point.

How to adjust the Depth of field
The Depth of field can be controlled with four parameters:
The focal length of the lens
The focal length of the lens is the second factor that influences the depth of field the most.
The longer the focal length is, the shallower the DOF is.
Let us sum up:
The shorter the focal length (14 mm), the deeper the DOF.
The longer the focal length (600 mm), the shallower the DOF.
