What is a Rack Focus?
Focus shifts from one plane of depth to another during the shot — from blurred foreground to sharp background, or vice versa. The sharp subject is always the one the audience should watch.
When to use it
Use to redirect attention within a single frame, to reveal a second character, or to build depth in an otherwise static shot.
Emotional effect
Reveals, attention shifts, depth, nuance. The viewer's eye is guided precisely.
Prompt formula

Common mistakes
- Not specifying direction — foreground-to-background vs background-to-foreground produce different emotional beats.
- Using with handheld or fast-moving camera — focus pulls need a stable frame.
- Leaving the reveal subject vague.

FAQ
Can AI models actually do a rack focus?
Some can — Kling and Runway show good depth-of-field handling. Including it explicitly increases the chance of the model attempting it.
How to write it?
Be explicit about both planes: 'rack focus from the sharp foreground hand to the blurred background face, which then snaps to sharp.'
Rack Focus vs depth of field?
Rack Focus is an active technique. Depth of field is a lens characteristic. Rack Focus uses shallow DOF to allow the focus to move.
