Forget the technical definition of focal length, it's unnecessary to
understand it or practice cinematography.
In this video I explain only the useful features of focal length in
cinematography and mainly how to exploit focal lengths for maximum
impact.
Footage is taken from Youtube, so is of poor quality. It's impossible
for me to rip high quality content (it's illegal) of every movie for
this. This video uses low resolution clips from movies only for
informational and educational purposes under fair-use.
