This defines a typical depth of field diagram containing three functions: Hyperfocal distance, nearest and furthest distance versus sharp distance (best focus). Pictures taken with an IR Camera illustrate the effect in the depth of field and its dependence on focal length. These pictures confirm ...
It differs from depth of field because it describes the distance over which light is focused at the camera's sensor, as opposed to the subject:Diagram depicting depth of focus versus camera aperture. The purple lines comprising the edge of each shaded region represent the extreme angles at ...
Depth of field applies equally to objects in front of your subject and behind it (well, not always equally, but we won't get into the complexities of that). Consider the nearby diagram of a man photographing a tree. The red zone indicates the depth of field. There is actually only a ...
The concept of CoC and computed Depth of Field: The computed blurred diameter of a "point" that is out-of-focus in the camera lens is called CoC (Circle of Confusion). A "point" is the theoretical size of a hypothetical speck of size zero when perfectly focused, which math can compute...
A simplified diagram of depth-of-field and the blurring effects caused by DOF-related optics. DOF is the depth-of-field, d0 is the distance to the focal point, d1 is the distance to the non-fixated object, s0 is the axial length, and b is the diameter of the blurred region of the...
and makes it easy to find the answers. Just type in the distance to the subject, the focal length being used and the f-stop and the App calculates the near and far distances of acceptable focus and therefore the depth of field. This is all shown on an easy to understand diagram. ...

DEPTH OF FIELD DEFINITION What is depth of field? Depth of field (DOF)is the term used to describe thesize of the areain your image where objects appear acceptably sharp. The area in question is known as thefield, and the size (in z-space) of that area is thedepthof that field. DO...

Extending the depth of field (DOF) is especially essential in thick and 3D sample imaging. However, it's difficult to achieve both large DOF and high resolution in a zoom microscope. Currently, the use of optical sectioning to expand DOF still has the pr
