| Key light |
Principal illumination source on a subject or scene, normally positioned slightly off center and angled to provide shadow detail. [See back light, fill light, three-point lighting.] |

| Keystoning |
Perspective distortion from a flat object being shot by a camera at other than a perpendicular angle. Nearer portion of object appears larger than farther part. |
| Kicker |

| Kinescope |
Also called "Kine." A method of making a film copy of a television program in the days before the existence of Video Recorders. A movie camera was aimed at a specially designed television monitor. Before video recorders were invented this was the only means of recording TV programs. Many kinescopes are now over 40 years old and have the potential to outlast videotapes that were created much later. |
