This can get complicated, but the simple answer is that the longer you set your focal length the shallower the depth of field. Example: Your subject is 10 meters (33 feet) away, using a focal length of 50mm at f/4; your depth of field range would be from 7.5 -14.7 meters (24.6-48 feet).

extended depth of field example In a nutshell, here’s how it works: several photos are taken at different f-stops, then a final composite is created using only the sharpest portions of each image. The result is a photo with an extended depth of field that looks natural, because sharpness still gradually decreases farther from the focusing distance (but just not by as much):

This extended depth of field image was constructed by Zerene Stacker software from a “focus stack” of 48 individual pictures stepped in depth by 0.005 inch (0.127 mm). As shown by the crop (at right), this image resolves the details of individual scales, over a total depth of more than 6 mm.

FOCUS STACKING & DEPTH OF FIELD. Focus stacking is a powerful technique for extending a photo’s apparent depth of field. It’s perhaps most useful in close-up and macro photography, since the camera lens’s highest f-stop is often insufficient to render everything in focus. It can even overcome the otherwise unavoidable sharpness loss from diffraction. However, focus stacking is also quite a.

1) What is Depth of Field? Depth of field is the distance between the closest and farthest objects in a photo that appears acceptably sharp. Now your camera can only focus sharply at one point. But the transition from sharp to unsharp is gradual, and the term ‘acceptably sharp’ is a loose one!

The area of apparent sharpness in an image is called the 'depth-of-field', and it is one of the main creative controls you have. But these conditions are far too strict for the real world and a figure of around 0.17mm is used in photography.

It is typically used to maximize depth of field in night photography and landscape photography. Notice that hyperfocal distance doesn’t depend on subject distance. Total depth of field (DOF): The distance between the farthest and nearest objects in a scene that appear acceptably sharp in an image. This can also be identified as the zone of acceptable sharpness in front of and behind the plane of focus (where the.
