SLR

Single-Lens Reflex. A type of camera in which you look

through the camera’s lens as you view through the camera

finder. Other camera functions, such as light metering and

flash control, also operate through the camera’s lens.

Spot metering

Sensitivity is concentrated on the approx. 3.5mm-diameter

circle in the center of the camera’s viewing area. Effective

when precise measurement of a special portion of the subject

is required.

TTL

Through-The-Lens. Most SLR cameras have built-in meters

which measure light after it has passed through the lens, a

feature that enables exposure readings to be taken from the

actual image about to be recorded on film, whatever the lens’

angle of view and regardless of whether a filter is used.

TTL auto flash

The camera’s light sensor measures flash light as reflected by

the subject on the film and shuts off the flash when measure­

ment indicates correct exposure. Because the sensor that con­

trols the flash receives light through the lens, TTL auto flash

can be used for bounce photography, fill-in flash, multiple flash

photography, etc. An additional advantage of TTL auto flash is

that you can use a wide range of aperture settings, while

ensuring correct exposure.
