Bokeh simulator & depth of field calculator
An error occured during page load. Please try refreshing the page.
This application calculates the camera depth of field and background blur in a photo and simulates it on a model together with perspective distortions and different types of lens blur (bokeh) for any lens, camera and distance combination. It includes also diffraction effects and hyperfocal calculation.
Activating the help mode shows description of the interface elements. By clicking on one of the buttons with question mark () you can read detailed information about particular panel of the interface.
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 10 and newer. The most fluid operation is provided by Chrome.

The depth of field simulation works now also on the model: ears, nose and face are blurred depending on the calculated depth of field.
Introduced perspective distortions on the model: the appearance of model's face changes at small distances.
Modified set of models - they now differ also in height.
Video 16:9 mode that changes the image ratio to typical for HD video.
New depth of field preview zoom feature allows to precisely see its range on the person even for small values of DOF.
The links generated for current settings are much shorter now. The old links will still work.
Thanks to the kindness of digicamdb.com administrator a list of digital photo and video cameras has been added. Based on this data the sensor size and focal length range is set.
Improved support for different screen sizes, especially small, mobile devices screens.
A mobile app for Android smartphones and tablets has been released on Google Play.
Enhanced offline version: easier installation: it now works independently from the browser installed in your system.
Stoping the bokeh simulation is now possible during processing.
Sensors sizes list cleanup: added large format film and very small sensors, division of the list into groups.
Expansion of the circle of confusion sizes list with values corresponding to typical video sizes. Division of the list into groups.
When the distance from the model to the camera is small, its head is placed on more interesting background instead of on the sky.
Faster background images loading thanks to better compression.
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.
