Through-the-lens metering

Index Through-the-lens metering

In photography, through-the-lens (TTL) metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. [1]

Exposure (photography)

In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance.

Flash (photography)

A flash is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene.

Nikon F3

The Nikon F3 was Nikon's third professional single-lens reflex camera body, preceded by the F and F2. Introduced in 1980, it had manual and semi-automatic exposure control whereby the camera would select the correct shutter speed (aperture priority automation). The Nikon F3 series cameras had the most model variations of any Nikon F camera. It was also the first of numerous Nikon F-series cameras to be styled by Italian designer Giorgetto Giugiaro, and to include a red stripe on the handgrip – a feature that would later become (with variants of stripes and various other shapes) a signature feature of many Nikon cameras. The F2AS was a current model when the F3 was introduced, and for a while both were sold concurrently. The earlier Nikons had developed such a sterling reputation for extreme ruggedness and durability that many Nikon F and F2 owners were initially reluctant to transition to the new F3 from the F2 series. The F3 was superseded by the F4 in 1988 and the F5 in 1996. Despite being superseded by the newer cameras, it remained in production through to 2001, with over 751,000 F3s produced through September 1992. It continues to be the longest running professional grade Nikon SLR. Long after production ceased, new bodies in boxes were available throughout the world, so an exact production number is not readily available.
