The three components that make up the Exposure Triangle are the Aperture, the Shutter Speed, and the ISO. Aperture, shutter speed, and ISO all work together to control the quantity of light that reaches the light-sensitive surface and the surface’s sensitivity using these three camera and lens parameters (ISO). These three parameters not only have an influence on the light captured in an image, but they also also have their own distinct “side effects.” Aperture regulates depth of focus, shutter speed blurs or freezes motion, and ISO may add or eliminate digital noise from a picture. Let’s go even further into those three components now.
