Depth of Field

Depth of field defines the spatial depth of an image captured in sharp focus. It can be adjusted depending on the situation and creative requirements.


Tips and rules for determining depth of field

Increase depth of field

  • Stopping down (smaller diaphragm equals larger f-number e.g. F16)
  • Use lens with shorter focal length

Decrease depth of field

  • Stopping down (larger diaphragm equals smaller f-number e.g. F2.8)
  • Use lens with longer focal length

Further information about depth of field can be found in the article on depth of field.

When using telephoto focal lengths or in macro photography, it can occur that by stopping down to the smallest diaphragm diameter it is insufficient to create the required depth of field for the image. Under the circumstances, changing the image’s build-up can deliver the desired result.
