We all know what f stops are and what they mean, but do you really understand the math behind it all? I thought I had a pretty good understanding of f stops and then I cam across this video below and I realized that while I did understand the basics, there is so much more going on that what you think.

So here it is, probably the most thorough and easy to follow explanation of f stops and the math behind it all. The video below is a great tool to help educate new photographers on what exactly an f stop is and behind the scenes action going on with each increase/decrease in a number. Special thanks to Dylan Bennett for posting this to YouTube.

What did you think? Pretty interesting stuff, huh? Did this video help you get a better understanding of F stops and what is going on behind the scenes of the numbers? Let us know in a comment below.
