How to Keep Exposure in Cinematography

How to Keep Exposure in Cinematography

In terms of cinematography, exposure is defined as how much time it takes the sensor to expose to light. In addition, exposure is based on how much light comes through and how sensitive the sensor is to light. Keeping the correct exposure in your photography is essential. One wrong move and your work could be ruined. Incorrect exposure could cause your cinematography to be overexposed or underexposed. Overexposure occurs when your camera sensor is exposed to too much light which results in unwanted white images in your photography. Underexposure occurs when your image doesn't get enough light and, as a result, your image appears too dark. Proper exposure is based on Aperture size, Shutter speed and ISO. Monitor these three components and you'll be able to keep exposure in your cinematography.

Instructions

    1

    Check the shutter speed before you photograph anything. Shutter speed determines the length of time the camera shutter is left open. You'll usually have the following Shutter speed settings: 1/500, 1/250, 1/125, 1/60, 1/30, 1/15 and 1/8. Choose a setting based on the type of image you are photographing. The larger shutter speeds expose your image to more light. Slower shutter speeds are used for very low light situations.

    Check your Aperture settings after you decide on a shutter speed. Aperture is the size of the opening in the lens when a photo is taken. Much like shutter speed, select your aperture setting based on your particular image. Aperture is measured in f-stops. Some of the aperture f-stop settings are f/2.8, f/4, f/5.6, f/8, f/22, etc. Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens. In addition, your aperture settings controls the amount of light going through your lens.

    Select an ISO setting once you've settled on shutter speed and aperture settings. ISO measures the sensitivity of the image sensor. ISO settings range from 100, 200, 400 all the way through 3200. The lower the number the less sensitive a camera is to light. Also, lower ISO settings produce finer grain in your cinematography. Use higher ISO settings in darker situations to get faster shutter speeds. A normal ISO setting is 100 since this setting usually produces clear, crisp shots.
