Now that we know some of the basic controls available on your camera, let's try and understand how they relate to each other.
A correctly exposed image can be made using several combinations of aperture and shutter speed. The relationship between the aperture and shutter speed that enables us to vary the settings and still maintain the same exposure level is called reciprocity. Each combination results in the same level of exposure but the aesthetics on the image will vary a great deal (we'll talk about these differences in much greater detail in future posts).
Here's how reciprocity works.
