Setting your light to F-11 or any other F-stop, then setting your camera to the same allows the camera to correctly capture the parts of the image
that the actual light falls on. If there are other areas of the image that has less or more light, it will show up in the camera on or about the same as
what your eye sees. Although the camera has limitations much more than the naked eye could see. About two F-stops above/below is the normal
capture area, even though the eye can see way more... Basically, this is considered the exposure range of the capture medium (chip). If your light is above or
below the range, it will not be captured/recorded. The purpose of fill lighting it to control this shadow areas that have less light than the main subject.
