Reading this article has brought amazing information to begin my photography career. It spoke about how photo exposure has three things: aperture, ISO speed, and a shutter speed. These three things combined are called the exposure triangle. It recommended to not have a subject neither over or under exposed. The article then begins to go more in depth with each part of the exposure triangle. Aperture controls the area in which allows light to enter. Shutter speed controls the duration of exposure. ISO speed controls the sensitivity of your camera’s sensor to a given amount of light.
