लाइट-मीटर इसके अंग्रेजी अर्थ का उदाहरण

8 lens, solar-powered selenium light meter, and just two shutter speeds.

Before the 1970s, many cameras had an "accessory shoe" intended to hold accessories including flashes that connected electrically via a cable, external light meters, special viewfinders, or rangefinders.

The light meter used a dual-concentric segmented silicon photo-diode to provide spot or centerweighted readings.

Exposure control was aperture priority AE using center-weighted light metering.

The first camera to feature automatic exposure was the selenium light meter-equipped, fully automatic Super Kodak Six-20 pack of 1938, but its extremely high price (for the time) of '225 () kept it from achieving any degree of success.

By the 1960s, however, low-cost electronic components were commonplace and cameras equipped with light meters and automatic exposure systems became increasingly widespread.

The next technological advance came in 1960, when the German Mec 16 SB subminiature became the first camera to place the light meter behind the lens for more accurate metering.

The Rolleiflex SL350 had open-aperture metering, an improvement over the Rolleiflex SL35 which was built with a stop down light meter.

The camera itself needed no batteries, though the prism light meter did (and the motor drive if added).

The F2 with plain/eye-level DE-1 prism (no light meter; see below) will work with either lens types.

It provided a virtually 100% accurate viewing image, but was a plain pentaprism eyelevel viewing head with no built-in light meter and so had no metering or exposure information display, except for a flash-ready light.

If a pentaprism head with a built-in light meter was mounted on the F2, the camera became an F2 Photomic.

The DP-1 had a center-the-needle exposure control system using a galvanometer needle pointer moving between horizontally arranged +/– over/underexposure markers at the bottom of the viewfinder to indicate the readings of the built-in 60/40 percent centerweighted, cadmium sulfide (CdS) light meter versus the photographer's actual camera selections.
