Photography Tutorial: Aperture
讲座描述
What is aperture? Aperture is the first part of the exposure triangle, and the first part of your camera that controls how much light enters and is captured.
Inside your lens is a hole. This hole can go bigger and smaller. This is your aperture, which is sometimes called the ‘iris,’ similar to the iris or pupil of your eye. Now if you make the aperture larger, do you think more light is let in or less light?
That one is easy - more light is let in when the hole is bigger. This means that increasing the size of the aperture will make your image brighter. Decreasing will make it darker.
How do we adjust our aperture?
An f-stop, also known as an f-number, is a method of describing the size of the aperture. This f-stop scale goes from f/1 to f/1.4 to f/2 to f/2.8 to f/4… and beyond.
There are 2 potentially confusing things about the f-stop scale.
First, the smaller the f-number, the larger the aperture. Visa versa, the larger the f-number, the smaller the aperture. So an f/2.8 is larger, and lets in more light than an f/11. Make sense?
