How do you turn on the light meter on a asahi pentax kx camera?

The metering system is always on on the K-series cameras. If your needle is not moving you need to replace the battery. The lens cover should be left on when the camera is not in use to preserve the battery, although the old style photocell draws very little current as the needle is the only thing it moves. The rest of the system is mechanical.

Is Camera Exposure caused because light is a wave?
The exposure is controlled by the camera's light meter
Will Pentax 35MM camera lenses fit any other camera?
Pentax screwmount lenses (M42) will fit differently branded cameras with the same mount. It will easily fit other camera mounts including digital bodies using a cheap adapter. Just make sure you use the correct version of the adapter that focuses correctly to infinity. With Pentax K-mount lenses, there are existing adapters that will mount these to a four/thirds system camera, the Canon EF EOS, the Minolta MA or Sony Alpha and the Leica M39 screw mount. Take note that in most digital bodies, the lens can only be used at manual mode. Some camera models will not meter through it even at stop down. Pentax dSLR bodies will meter through them and add Shake Reduction and focus confirmation even if the lens is full manual.
How do you read the metering system of a K1000 Pentax Asahi camera?
The exposure is (in theory) correct when the needle on the right side of the viewfinder is in the center of the gap in the black scale. This will give you a good exposure under average lighting conditions. A good trick is to meter off the palm of your hand, turning it until the meter shows the highest reading and then adjusting the exposure. Then open the exposure 1 f-stop equivalent. This approximates an incident light reading. A gray card can also be used. If you use an 18% card, do not open up the extra stop.
What type of camera has a sensor that converts light into eletrical charges?
Any film camera with a light meter, and every digital camera, has a sensor that will do that.
What is a light meter used for?
If you mean a light meter that is used in a photographic studio, then it measures the light that hits the 'subject' from the studio lighting, the light meter then tells you what you need to set your camera to, for the correct exposure.
What is a foot candle meter?
The type of light meter that measures the light intensity in pictures is a foot-candle meter. They help in setting the camera right and help in calculating the best lighting.
How to compare the brightness of the old light bulbs to the new energy effiecint bulbs?
Use a phone app like light meter which uses the camera to give a luminosity level.
Will chinon slr lenses fit digital camera?
Chinon lenses are either M42, 'Pentax screw.' which can fit any digital body with the relevant adapter, or Pentax K bayonet which will fit Pentax or (most) Samsung SLRs. NB they will only meter stopped down to the taking aperture, and offer neither autofocus nor shutter priority/programmed modes. There is also the fact that film SLR lenses need longer focal lengths than their digital cousins due to the sensor being smaller, thus a 50mm standard lens for film is a short telephoto for digital.
What are the benefits of light meters?
A light meter is more precise and versatile than the built-in exposure meter on typical SLR/DSLR/digital cameras..Once the type and speed of the film (in the case of older SLR camera films, or the ASA setting on your camera) are entered or set and matched on both camera and meter, you can use the meter to measure the strength of the light source shining on the subject of your photograph or the amount of light and/or shadow that is reflected by the subject (i.e., a person) to determine the shutter speed and aperture (lens opening) settings to get a properly exposed photograph (not so dark that you cannot discern an image or so overexposed that the necessary details are "washed out," except in certain situations like shooting a silhouette of a person or object against a lighter background).
Who invented the first light meter?
who envented light meter
How do you properly use exposures with photography?
To use exposures, it is best to know what they are. Exposures are combinations of film speed, shutter speed, and aperture. To use them best, a photographer should use the results (via the camera's light meter) to see if the combinations will create the desired light in camera's sensor (digital) or film.
What is Spot Meter in photography?
It is a light meter reading of a small centralized area within the camera's field of view. I don't know what the angle would be for various cameras that have a version of the feature, but I can say that some old hand held spot meters have a measuring angle of 1 degree in a field of view of about 35 degrees. In many cases, the spot meter area is marked within the view finder in some way. Correct use of a spot meter (or for that matter, pretty much any camera light meter) requires a good understanding of metering concepts and the image medium, whether it is film or digital.
