Explaining What the Hell F-Stop Is, and How It Can Change Your Photography

F-stop is to photography beginners what inorganic chemistry is to an MFA graduate: some kind of black magic that only makes sense to experts. That said, I'm sure plenty of seasoned photographers use f-stop numbers without knowing what they really mean, too. But no more, because this video explains the concept in a way that makes complete sense.

Dylan Bennet talks you through aperture size, focal length, and how they combine to produce the elusive concept that is f-stop. OK, so there's a little math, but it's not too complicated, and the understanding you'll gain makes it worth it. He wraps up by explaining how photographers use the f-stop terminology—what people mean when they say they're going up or down stops, and what's meant by a fast or slow lens—and provides a neat trick for memorizing the scale.

Already know this stuff, it's simple to me now. Could do with knowing t/stop but that's less relevant to photography, more relevant to cinematography.

Right now I want to find out how sensors work, haven't quite gotten around to researching it properly but I remember seeing a video and the guy explained the pixels as buckets, and he was talking about something where one of the buckets gets filled with too much light, then it overflows and goes into other buckets, however, these other buckets are different colours, something like that.
