Rack Focus

Rack Focus example frame

Shift focus between distances during a shot to transfer attention, reveal information or connect two dramatic elements.

What it does

A rack focus changes the plane of sharp focus during a shot, transferring attention between subjects at different distances. Its narrative force comes from timing: the shift can follow recognition, anticipate danger or reveal that the apparent subject was only a distraction. Bong Joon-ho’s Memories of Murder, photographed by Kim Hyung-koo, uses changes of visual attention within layered staging to connect investigators and information. Steven Spielberg’s Jaws, photographed by Bill Butler, offers another useful reference for directing attention between people and potentially threatening activity within a frame. The focus change should have a readable starting point and a motivated destination. Establish enough depth separation for the transition to register, and allow a moment to recognise each target. Avoid it when both elements are already equally sharp, or when repeated pulls replace meaningful blocking with conspicuous technical punctuation.

The prompt

Begin with the foreground glass sharp and [Subject] blurred beyond it; over two seconds, pull focus to the subject’s sudden recognition. ARRI ALEXA 35, Cooke S4/i 65mm at f/2, ARRI LogC4-to-Rec.709 LUT. Set focus marks at 0.8 and 2.5 metres. A 3200K ARRI T1 Fresnel skims the glass; a 4300K SkyPanel S60-C keys the face. Keep framing locked.

Replace [Subject] with what you are shooting. Everything else is deliberate: the gear, stock and lighting are what push a generator towards this look.
