Depth-of-field Close up table
This table shows the depth-of-field for close up photography at different apertures and reproduction scales. The table can be used with lenses of different focal lengths because the depth-of-field is the same on any lens when the scale of reproduction and aperture is the same.
You can calculate the scale of reproduction using the following formula:
| Scale of reproduction = | Extension increase |
Focal length |
Scale of
reproduction |
Depth-of-field in mm at aperture no. |
