The Pentax K1000 exposure meter measures the light coming through the lens.
The Pentax K1000 was sold between 1976 and 1997 by the Asahi Optical Co. The camera, which uses 35 mm film, is designed for experienced photographers and has no automatic settings option. Photographers must set the exposure of their photographs manually. In addition, close attention must be paid to the built-in light meter, and the shutter speed on the camera and the f-stop on the lens both must be set manually. The f-stop controls the aperture, or the amount of light coming through the lens, when the picture is taken.
Instructions
1. Take off the lens cap to activate the camera's light meter. Look through the viewfinder. The meter indicator is a needle on the right side of the frame. It has a plus and minus to indicate that there's too much or too little light for the picture.
2. Set the shutter speed by turning the shutter-speed dial on the top right of the camera body. Use a fast shutter speed, such a 1/250th of a second, when you want to shoot action or in bright sunlight. Use a slower shutter speed, such as 1/60th of a second, with dimmer light or for stationary subjects.
3. Locate the aperture ring, also called a diaphragm ring, on the lens. It's the threaded ring closest to the camera body and it's marked with a series of numbers.
4. Look through the camera's viewfinder again.
5. Twist the aperture ring clockwise and counter-clockwise until the light-meter needle rests in the center of the indicator in the viewfinder. This means the picture will be properly exposed.
