Effect
Depth Of Field
Blur based on depth cues so subjects stay sharp while backgrounds fall away.
Lenses focus on a plane; everything nearer or further softens according to aperture and distance. Photographers use that fall-off to separate subject from ground. Cinema and computational photography later faked or extended it with depth maps.
This effect blurs from depth cues so sharp subjects can sit in soft space without a tilt-shift lens.
