What is Aperture?
Aperture is when you press the shutter button on your camera to see the glimpse of the scene you are looking to capture. The aperture you set impacts on the size of the hole. Aperture is measured in F-stops and is known as the F/Numbers at the Digital Photography. For example f/2.8, f/4, f/5.6,f/8,f/22 etc.
When moving from one f-stop to another it doubles the size of the opening of the lens and how much light is getting into the lens. The higher the f-stop the less light get into the camera and the lower the f-stop number the more light gets in. Also the shutter speed will change from one f-stop to another.
