Photography - Bokeh - DSLR Camera - Lens - Sharpness
Description:
The page provides a depth of field (DOF) calculator for
photography. The depth of field is the section or range
of the photo which will be sharp. The section is defined
by a near sharpness limit distance and a far sharpness
limit distance. Anything between these two limiting distances
will be sharp. The sharpness limes are based on the f-stop
value, lens focal length, subject distance and the circle
of confusion of the camera.
Directions:
Note, if you manually enter the lens
focal length, subject distance or circle of confusion,
the ENTER or RETURN keyboard button needs to be pressed.
This will cause the calculations to be updated.

of 0.030 millimeter for a 35mm format. The circle
of confusion is adjusted by the crop factor if needed.

This is the aperture setting to
be used when shooting your photo. |

The focal length of your lens
in millimeters. Note, do not multiply the focal
length by the camera body's crop factor. This calculator
automatically adjusts and calibrates the lens. |
| subject or focus distance |
This is the distance from the camera to the subject
being photographed. |

This is related to the final resolution
of the image. It is based on the sensor size, image
