As you can see from the above, an f stop of f/1.4 is really wide. It is letting a lot more light into the lens and ultimately onto the sensor than, say, f/8. Thus: The lower the f stop number, the wider, or bigger, the aperture. So, if someone tells you to âstop downâ, they are referring to decreasing the size of the aperture, which is achieved by increasing the f stop number.
