To achieve camera exposure, you need to use the three things that control it. The three things are aperture, shutter speed, and ISO which form the “exposure triangle”. The aperture controls the area over which light enters into the camera. It’s described in a f-stop value. The higher the value, the smaller the hole around the lens which lets less light in that is used for brighter areas. The smaller the hole around the lens lets more lights in for darker areas. The shutter speed controls the period of time of exposure. With faster shutter speed, less light is let into the camera. Faster shutter speed is used for more powerful freezing of an image. Slow shutter speed is used to catch a more exaggerating appearance of motion in an image. Iso speed determines how sensitive the camera is to incoming light. Low ISO speed produces lower image noise. High ISO speeds can dramatically increase image noise making photos blurrier and more pixelated. There are many camera modes, but manual mode is what I’m using most. Manual mode is where you control everything, the aperture, shutter speed, and ISO speed.
