The exposure triangle helps you understand how aperture, shutter speed and ISO work together to determine the exposure.īefore you learn how to use the exposure triangle, let’s look at aperture, shutter speed and ISO. There are three fundamental elements which control exposure on a digital camera: aperture, shutter speed and ISO. When a photo is over-exposed (too bright), detail will be lost in the highlights (brighter areas of the image). If a photo is under-exposed (too dark), detail will be lost in the shadows (darker areas of the image).

When taking a photo your aim should always be to achieve the best exposure possible, so your photo doesn’t appear too light or too dark.

Exposure refers to how bright or dark the resulting photo is.Īchieving a good exposure is essential for creating high quality, visually appealing photos. When you take a picture, light from the scene enters the camera and hits the sensor, creating a digital image. Do your photos sometimes come out too dark or too bright? Getting the perfect exposure is a common problem for even the best photographers, and the best cameras! In this tutorial, you’ll learn how to use the exposure triangle to take control of your camera’s aperture, shutter speed and ISO settings – so that you can shoot perfectly exposed photos every time.
