Is it possible to achieve a variable depth of field in post-production?

It is certainly possible to emulate the Cinefade effect in post-production. We would however argue that it is a creatively inferior and more expensive method of achieving a depth of field transition.

One could shoot a scene at a deep depth of field and in post-production mask around and isolate the subject to blur the background with a Gaussian blur or similar tool. Once however camera and subject movement come into play, as well as changes in focus and zoom, this can become time-consuming and costly.

Moreover, the characteristics of lenses and their bokeh are very hard to emulate with software and cinematographers will always want to retain control and shoot everything in-camera, which is one of the value propositions of our Cinefade system.

iPhone Xs adjustable depth of field effect

Mobile phones such as the Huawei P10, the iPhone 11 Pro and Samsung Galaxy phones have a ‘depth effect’, ‘portrait mode’ or an ‘adjustable depth of field effect’ built-in, which uses dual or triple cameras and software to blur images and adjust depth of field after taking a picture. It is not a big leap to imagine this feature will soon be available in video too.

Light field technology, such as the Lytro camera (which has been bought by Google) offer an interesting alternative to traditional cinematography and it will be several years before the technology is affordable and used by filmmakers.
