See - I mostly take this sort of thing for granted, but then I did fizziks at skool and (Open) University - so "how light works" seems like the bleeding obvious to me!

For other reasons I clicked on the cute little video here and quite liked the explanation with sideways reference to pinhole cameras and lens apertures.

Maybe others will find this helpful - the whole jargon and explanation of why f/2 is bigger than f/64 and by how much and isn't 64 the bigger number etc is just so-not-helpful at times. But picturing what you're doing in shorthand or cartoons should come easy to the seasoned tog.

Anybody seen any similar little cartoons/video clips/explanations that cut right through the C.R.A.P??

At my school you could either take fizziks or music, not both. So I took music, and failed. rolleyes
