Controlling Exposure

To control the exposure of your image, you need to know how to adjust the shutter speed, the aperture, and the gain control or element sensitivity. In general, your shutter speed is responsible for the motion blur of the image, and it's usually set to double the frame rate. However, the feature can also be used stylistically, as a higher shutter speed makes the action in the shot appear more staccato, and a lower shutter speed makes the action appear more blurry, and almost dream-like. Another element is aperture, which controls how much light enters the lens; the larger the aperture, the more light that gets in. Aperture is also responsible for the depth as field, as allowing a lot of light in the lens gives off a shallow depth of field, and vice versa. For gain control, its role is changing the sensitivity of the sensors, which allows less light to be needed in low-light scenarios. However, adjusting the gain should be used minimally because it creates digital noise that gives the image a grainy feel.
