What Is Aperture and Shutter Speed?
First off, what is shutter speed? It’s an exposure setting for how long your camera’s shutter will remain open when you click the shutter button. It’s almost like blinking your eyes really fast. You can leave them wide open for like an entire minute, or you can open and close them in a second or less. Most advanced cameras come with a wide range of shutter speeds, from 1/2500th of a second to as long as 15 seconds. The longer the shutter remains open, the more light that hits the camera‘s sensor. If it’s not open long enough, your image may be underexposed—fairly dark. If it’s opened too long, your image may be overexposed—too bright. Open too long without a stable tripod to hold the camera steady, and the shots will probably be too blurry. Shutter speed works in conjunction with the aperture and ISO settings to determine the appropriate exposure based on the lighting conditions images are captured in. When using shutter priority, it means that you’re going to manually set the shutter
