Depth of field (photogrammetry and remote sensing) Depth of field (DOF) refers to the range of the distance between the front and back of the subject measured by imaging in front of the camera lens or other imagers. Aperture, lens and object distance are important factors affecting depth of field. After focusing, the range before and after focusing, that is, the clear image presented in the range of front and rear distance, is called depth of field. There is a certain length of space in front of the lens (before and after focal length adjustment). When the subject is located in this space, its imaging on the negative is just between the two diffusion circles before and after focusing. The length of the space where the subject is located is called the depth of field. In other words, the blur of the image presented by the subject on the negative plane of this space is within the limited range of the allowable circle of dispersion, and the length of this space is the depth of field.
