Depth of field, rack focus, and optical tricks that guide the eye through space.

6 techniques

Bokeh

BokehBokeh describes the character of defocused detail, including highlight shape and transition edges, rather than merely shallow focus.

Deep Focus

Deep FocusDeep focus keeps a substantial continuous range of distances legibly sharp within one shot.

Focus Change

Focus ChangeThis focus-change variant shifts quickly from one depth plane to another, ending decisively instead of lingering in intermediate blur.

Rack Focus

Rack FocusA rack focus deliberately transfers sharpness between two distances during a continuous shot while the composition remains stable.

Shallow Focus

Shallow FocusShallow focus restricts the sharp depth range around a chosen subject while nearer and farther distances become soft.

Split Diopter

Split DiopterA split-field close-up attachment focuses one image region nearer while the uncovered region retains a farther focus distance.
