1.In optice, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. 

2. Aperture refers to the access given to light from the lens to the camera sensors. The size of your aperture

(the diameter of the hole through which light enters the camera) controls the amount of light entering your lens. 

3. The closer your subject is to the camera, the shallower your depth of field becomes. Therefore, moving further away from your subject will deepen your depth of field.

4. Focal Length refers to the capability of a lens to magnify the image of a distant subject. This can get complicated, but the simple answer is that the longer you set your focal length the shallower the depth of field. 

5. Managing depth of field is one of the most important tools at your disposal, because having tack sharp images is one of the most important factors to getting that great shot.

6. The shallow depth of field is a good way to make your subject stand out from its background and is great for portrait photography. Shallow DoF can also be useful in wild life photograpy where you want the subject to stand out from its surroundings.

7. The most macro images are produced in low light and with a longer focal length, the depth of field is often very shallow. Adjust your lens to the smallest aperture that the light will allow.

8. Shallow depth of field is used primarily to isolate the subject from its environment, and it is used a lot in portrait work, macro photography, and sports photography. Deep or Large Depth of Field.

9. To achieve a very deep depth-of-field, you need an aperture setting of f/16 or smaller. Keep in mind that the focal length of your lens also affects depth-of-field

10. It is measured as the distance from the nearest object plane in focus to the farthest object plane that is simultaneously in focus, and is measured in microns.
