OK folks,
I know I am going to lose some of you on this one.
I am going to write a four letter word:
"MATH."
I hate math.
But if you can watch this video
and do NOT worry about the math -
you'll learn a lot of valuable information about your camera.
You do not need to understand the math to
grasp the concept of f stops.
But understanding f stops is key to improving your photography!
This is the best tutorial I have ever seen on this topic.
I never knew how the f numbers were derived before.
