How to use the aperture on a camera?
What is the purpose of aperture on a camera?
Open the aperture = more light ==================> Close the aperture = less light
The aperture is equal to the focal length of the lens divided by its diameter.
It is a square root progression 2 (√(2) =1.414,which gives the following values: f/1.4 – f/2 – f/2.8 – f/4 – f/5.6 – f/8 – f/11 – f/16 – f/22, etc.
Adjust the aperture on a camera
Between two values of the scale, the aperture will let in twice as much light, i.e., when you increase it by one notch, you’ll double the amount of light entering, and when you decrease it by one notch, you will reduce the amount of light entering by half.
