FILM
LEXICON

Aesthetic quality of out-of-focus background areas describing how lights and soft edges appear outside depth of field.

Optical artifact from direct or indirect light in optics that creates characteristic reflections and halos.

A shift of the focus plane during a shot that redirects attention from one object to another.

Three-point lighting is the fundamental lighting setup consisting of key light, fill light, and back light, which creates depth and modeling.

A lens with variable focal length that allows continuous adjustment of magnification without changing physical position, providing operational flexibility at the cost of some optical characteristics.

A lens with a fixed focal length that cannot be adjusted, offering superior optical quality, faster apertures, and minimal optical aberrations compared to zoom lenses.
