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 http://dofsimulator.net 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
- 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.
