Saying " f (4) = 16 " is like saying 4 is somehow related to 16. Or 4 → 16. Example: this tree grows 20 cm every year, so the height of the tree is related to its age using the function h: h(age) = age × 20. So, if the age is 10 years, the height is: h(10) = 10 × 20 = 200 cm.

WebF-stops (also referred to as f-numbers) refer to how open or closed the opening in your lens is. The wider the aperture – the opening in the lens – the smaller the f-number. For example, in the chart above f/1.4 is quite wide open (a ‘wide’ aperture), while f/16 is little more than a pinhole ( a ‘narrow’ or ‘small’ aperture ).
