In case you hadn't seen it, there is a website that is a DOF calculator as well as a bokeh simulator that is quite nifty, you can visit it here. Now the developer behind the web site has released a free Android app that will do the same thing for you along with some improvements.


Mobile version of the online tool that calculates and simulates the depth of field and background blur (bokeh) on a photo including perspective distortion and diffraction effect. It also visualizes the DOF range.

You can choose from 4 ultra high resolution backgrounds, 8 models of different height and 10 kinds of bokeh.

Parameters that can be set:

  • Lens focal length
  • Aperture
  • Sensor/film size or camera model
  • Distance of the model and the background from the camera

The application calculates:

  • Depth of field range
  • Background blur size
  • Hyperfocal distance
  • Diffraction effects

All changes in parameters directly affect the preview – you can easily observe their influence on the resulting photo. Saving the parameters sets on a list allows to directly compare the outcome of different equipment configurations.

Comprehensive help and a guide that presents all the features helps to understand the meaning of all presented parameters even for beginner amateurs of photography.
