VARY DEPTH OF FIELD IN FILM
CINEFADE VARIES DEPTH OF FIELD IN A single MOTION PICTURE shot AT CONSTANT EXPOSURE, ENABLING THE GRADUAL TRANSITION BETWEEN A SHARP AND A BLURRY BACKGROUND.
“The Cinefade is a really useful and very subtle tool to use in moments of extreme drama. A way of immersing an audience inside the mind of a character during a pivotal moment.”

“There are a handful of moments in The Commuter where Liam Neeson’s character discovers clues while riding on a train. Director Jaume Collet-Serra and I wanted a severe depth-of-field shift to accentuate his experience - something to isolate him from his surrounding world. Cinefade was exactly what we were looking for.”
The in-camera effect gives Cinematographers control over the sharpness of the background. The gradual transition between a sharp and a blurry background in a single shot enables a novel form of cinematic expression.
Depth of field in motion picture is a powerful cinematic storytelling device. In the past, Cinematographers have always been limited to choosing either a shallow or deep depth of field that stays consistent throughout the shot.
A variable depth of field has vast creative applications. Instead of simply communicating the emotional state of a character, the effect of a changing depth of field may be used to express a shift in the subject’s emotional state.
The transition from a sharp background to a blurry background forces the viewer to shift his focus to the subject. The Cinefade could be used in narrative film and TV to immerse the viewer into a protagonist's world or in a commercial to make a client's product stand out from the rest.

How to change depth of field at constant exposure.
The iris is operated to vary depth of field.
A light filter keeps exposure constant.
Depth of field change blurs the background
Depth of field is manipulated by increasing or decreasing the diameter of the lens' iris. When the lens is focused on a foreground subject, the background will become blurry and go out of focus or vice versa become sharp.
However, by opening or closing the aperture more or less light hits the camera's digital sensor or film, affecting exposure.
a variable ND filter keeps the exposure constant
There are various ways of compensating for the change in exposure caused by a varying aperture size. Shutter speed and ISO sensitivity could be slaved to the iris but these methods cause distracting motion blur and sensor noise and can not be employed over a wide variety of different camera systems.
Cinefade uses a variable ND filter that sits inside a matte box in front of the camera lens and is slaved to the iris. This solution is compatible with any digital and film camera system and cinema lens.

Full Cinefade set up
The custom Filter Tray fits inside a matte box and is connected to the custom cmotion Lens Control System. The system will work with any digital and film camera and cinema lens with a manual aperture and geared ring.
Benefits
Compatible with all cameras and cinema lenses.
Cinefade uses a light filter to compensate for the change in exposure rather than shutter speed or ISO compensation. The camera accessory is compatible with all film and digital cameras that use a cinema lens with manual aperture control
Any Cinefade range Up to 5 T-stops.
Cinefade is not limited by the camera's shutter or ISO capabilities. It is possible to to achieve a Cinefade of up to 5 T-stops within the lens' limits without any loss in quality or undesirable artifacts, such as unnatural motion blur or sensor noise.
Fast and easy set-up and calibration.
The custom cmotion software and custom Filter Tray work together to allow fast and easy calibration of lens and Filter Tray at the push of a button, as well as full control over the Cinefade via a slider on the hand unit.
No loss in optical picture quality
Cinefade uses Formatt-Hitech polarizing filters to attenuate the light with no loss in optical picture quality up to 5+ stops stops of extinction. There are no undesirable artifacts, such as unnatural motion blur or sensor noise to worry about.
