The light meter lets you set either the shutter speed or the aperature. When you look in the view finder you'll see either a red positive or red negative sign. This means there is either too much light or not enough light based upon the cameras settings. If you want to control the shutter speed set it where you want it to be. The aperature setting is the variable setting that you move until you see a green dot in the view finder. When a green dot is found in the view finder you have the correct settings. If you can't get a green light by adjusting the aperture setting then the shutter speed is too fast for the lighting conditions. In this case move the shutter speed to a slower setting then adjust the aperture ring again. It's all about the lighting with this camera. If you do not see a green light in the view finder you do not have adquate light to expose the film properly. By the way, you should not hold a camera in your hand with a shutter speed of one sixtieth of a second or less. The picture will blur from motion. This is much easier to show than explain. I .

Is Camera Exposure caused because light is a wave?
The exposure is controlled by the camera's light meter
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.
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?

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.
How do you measure incident light?
Incident light is the light that falls from the source onto the subject. It is usually measured with a hand-held instrument (often digital, these days) called an incident-light meter. Readings are usually taken from the subject's position, with the receptor-cell of the meter facing back toward the camera. Some incident-light meters are dedicated to that function. Others can measure "reflected" light (light that is reflected from the subject) and have a module for measuring incident light as well.
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.
Why might a scientist use a light meter?
Scientist use a light meter to show how light in shining on a surface !
Instrument used by umpire in cricket to measure light intensity?
lux meter or light meter
