Getting the correct exposure when shooting with a digital camera is easy. In this article, you will learn what a histogram is, how it can be used to control exposure, and what difficulties you may encounter when determining exposure in practice. I dare to hope that you already know the theoretical basics of exposure and know what shutter speed, aperture, exposure correction, dynamic range, what are the ways of exposure camera and exposure detection modes.
