Only one photo can be obtained only with accurate exposure. If the exposure is inaccurate, the image quality will be damaged. In severe cases, it cannot even be remedied. Accurate exposure is based on accurate metering. Grasping the principle and method of exposure and metering is an important part of photography technology.
We adjust the aperture and shutter speed, press the shutter button, at the moment the shutter is opened, the light passes through the aperture of the aperture to make the film sensitive and forms a latent image on the film. This process is called exposure.
The exposure obtained on the film is the product of the illumination and the illumination time. That is: Exposure = Luminance (lux) × time (seconds), the film can be accurately exposed by adjusting the aperture and shutter speed.
