Aperture controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as an f-number (written as “f/” followed by a number), such as f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32.
By increasing and decreasing the levels of aperture, I have ben able to add more depth to my photos and see other ways to give them a bolder image. I used camera lens and placed them 10 cms apart to make the photos even. I changed the F number from F2 up to F22 to get a broader range of images.
