It’s helpful to understand your equipment, to know how to set up your camera so your subject will be in focus and properly exposed. Knowing how everything works will allow you to avoid mistakes and the frustration that accompanies them. If you’re especially enamored of technical things, you’ll probably enjoy trying out all your camera’s menu choices, dials, and buttons, learning what it’s capable of. But just as most of us don’t pull out our phone simply to play with the settings, understanding the technical aspect of photography isn’t our final goal. Rather, it’s the means to an end. We want to create quality photographs.
