Cinefade: variable depth of field in one shot

London-based filmmaker Oliver Janesh Christiansen has developed Cinefade, a unique system that enables cinematographers to gradually vary the sharpness of the background in a motion-picture shot at constant exposure, while keeping the foreground in focus, in partnership with cmotion Lens Control Systems of Vienna, Austria.

Using depth of field creatively

Cinefade is an in-camera effect that can immerse viewers in a story or make a client’s product stand out in a commercial, enabling a whole new form of cinematic expression. Christopher Ross BSC says: “Cinefade is a really useful and subtle tool to use in moments of extreme drama.”

Depth of field is a powerful cinematic storytelling device. In the past, cinematographers have been limited to choosing either a shallow or deep depth of field that is consistent throughout the shot. Cinefade gives the opportunity to explore the creative potential of a variable depth of field. Fading from a deep to shallow depth and thus gradually blurring the background could, for example, communicate a shift in the subject’s emotional state in a narrative or guide the viewer’s eyes to focus on a product in a commercial.

A video demonstrating the effect is available at www.cinefade.com

Cinefade uses a custom cmotion lens control system to vary iris diameter, changing depth of field. A custom-built variable Neutral Density filter sits inside a matte box and keeps exposure constant by slaving the filter motor to the iris motor.

The Cinefade system

  • works with any digital or film camera and cine lens
  • is quick and easy to set up
  • is simple to operate
  • allows for a range of up to 5 T-stops

Cinefade is currently being used by DoPs for TV dramas, feature films, commercials and music videos and is available as a rental-only item in London and Los Angeles.
