Photography is all about light.
Every camera ever manufactured, regardless of whether it is a film camera or a digital one, regardless of its bells and whistles, is, at its core, nothing more than a box that allows light in at one end—the lens—to be recorded as an image at the other, either on photographic film or on digital media.
There are a lot of things that go into making a good photo, but one of the primary elements is controlling and managing the amount of light—the exposure— coming into the camera at thatfront end.
Beginning photographers can sometimes have a hard time with the concept of exposure. And that’s too bad because an understanding of exposure is essential to moving beyond your camera’s automatic settings and taking creative control of your photography.
With that in mind, I think this video from Matthew Gore of Light and Matter is especially helpful in how it explains the basics of photographic exposure.
