Solution
The human eye is supported by one of the most sophisticated “automatic exposure meters” known to man. As we look at a subject, no matter how light or dark it is, the iris in our eye will adjust to it very quickly.
Most modern cameras work in a similar way. They have an automatic exposure meter which reads the amount of light entering the camera and this information is used to make an adjustment to it’s aperture - a device which is very similar to the iris in our eye.
