Correct exposure, английский
The combination of aperture and shutter speed that yields a full-toned negative or slide that yields the best possible tonal representation of the scene onto film or sensor. the constants in an exposure calculation are the speed of the film and the brightness of the scene; the variables are the aperture and shutter speed.
Single-lens-reflex, английский
Or slr. a type of camera that has a movable mirror behind the lens and a ground glass for viewing the image. film sits behind the mirror assembly, which swings out of the way when an exposure is made. "single-lens" distinguishes it from tlr, or twin-lens-reflex cameras, where separate lenses are used for viewing and taking.
