A Decibel Scale is a scale that measures intensity. Then there are also octaves that are also logarithmic scales but they measure frequency. In this assignment I decided to focus on the f/stop of logarithms which regulates how much light is allowed through the lens by varying the size of the hole the light comes through. The f/stop remains a source of confusion and mystery to many photographers, even to some who use it all the time. In the image below it shows how f/stops works and in this case it is a camera setting corresponding to a particular f-number.
