This application calculates the depth of field in a photo, visualizes it and simulates the background blur (bokeh) based on parameters like: lens focal length, aperture, sensor size and distance of the object and the background from the camera. Changes in parameters are immediately visible in the simulation. This allows to easily observe how they affect the final effect.
Activating the help mode allows to obtain additional description of the interface elements. By clicking on one of the buttons with question mark () you can read more detailed information about each panel of the interface.
All calculations are performed with assumption that the lens is a single, thin lens. Such approximation can cause slight differences from the actual values observed in reality.
The simulator makes use of modern web technologies, such as HTML5 and CSS3 and may not work correctly in older browsers. It has been tested to work with Chrome 20.0, Firefox 4.0, Opera 12.0, Safari 6.0, Internet Explorer 9 and newer.

Completly new advanced bokeh simulation feature. It allows to simulate different types of real-world background lens blur: from soft disks, through polygonal diaphragms to rings from a catadioptric lens.
Added option that allows to lock the distance between the model and the background - it simulates the photographer movement with constant position of the model.
The offline version allows to use the simulator without an internet connection. It is enclosed in a ZIP archive and can be run on any operating system. In order to reduce the size, it contains only four backgrounds and four models.
After downloading, you can simply decompress it anywhere on your hard drive and open the index.html file located in the root directory.
WARNING! The offline version works 100% correctly only in Mozilla Firefox. Other browsers may have problems when opening it directly from a hard drive, althoug it works correctly on a server.
