f-number - Wikipedia

WebSince f/1.4 is one stop slower than f/1, it has an AV of one (1) Since f/2 is two stops away from f/1, it has an AV of two (2) Since f/2.8 is three stops from f/1, its AV is three (3) ... WebAnnoyingly, a low f-number, like 2.8, is "large", and a high f-number, like 18, is "small". The f-number is essentially the size of the hole in the lens that lets light in to the camera. The larger that hole, the more light gets into the camera. That means you can use a lower ISO (less noise) or a higher shutter speed to get a picture. diaper raffle tickets template printable
