![]() ![]() The larger the opening, the more light that will be able to enter, thus increasing the brightness of your image.Īperture is measured in f-stops such as 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, and so on. The definition of aperture in photography is the diameter of the opening of the optics that lets light travel through the lens to the sensor. This means that you'll be letting in less light, to your camera sensor which will make your image darker. In contrast, if you decrease your ISO from 800 to ISO 400, you wlll be decreasing light sensitivity. When you increase from 50 to 100, you are doubling the amount of light being absorbed by the sensor which will increase the brightness of your exposure by one stop. For example, going from ISO 50 to ISO 100 is one full stop. In terms of stops, it is very easy to remember with ISO, as one full stop comes from doubling the number. An easier way to say this would be that a lower number ISO will not absorb as much light as a higher number, thus keeping an image darker. The higher the number, the more sensitive it is. Put simply, the lower the ISO number, the less sensitive to light that your camera sensor will be. Now what does sensitivity to light mean in the context of photography? Originally, it referred to how sensitive film was to light, but now it refers to the camera’s digital sensor’s sensitivity to light. ISO (International Standards Organisation) is the standardised industry scale for measuring sensitivity to light. I know this may seem overwhelming, but keep reading and we will get in depth to what each piece of the triangle means.Ī properly exposed image. These will all be an increase of one stop to the exposure, which would brighten your image by letting in more light.īelow is an example of a correct exposure, an underexposed image by two stops, and an overexposed image by two stops. For example, you can increase your exposure by one stop by increasing your ISO from 100 to 200, your shutter speed from 1/60th to 1/30th, or aperture from 11 to 8.

In mastering the art of exposure, you can even reach new heights with your visual artistry. Learning how the Exposure Triangle works is important for any photographer who wants to improve their photography by using proper photographic techniques.

Exposure is determined by three elements: ISO, aperture, and shutter speed. ![]() ![]() In more simple terms, it is how bright or dark the scene you are capturing is and how light or dark the resulting photograph will be. What is exposure in photography? Exposure is defined as the amount of light reaching the electronic sensor, or film. ![]()
