Now comes the math and science section. Now, don't freak out.…We're not going to really blow your mind and, if…you hated math and science, don't worry about this one.…Don't fast forward.…I want to explain another way you can…adjust your lights very easily and very effectively.…Now, you'll hear a term called the inverse square law,…and already your head's probably getting bigger, but it's simply this.…If my light is not bright enough, instead of playing with the knobs…I can actually move it closer or further away.…Now if i move it closer it's not like a one-to-one relationship where, you know…I move it half the distance it gets twice as bright, it actually is the squaring.…
So if I move it closer.…Half the distance, it actually gets four times brighter.…And conversely, if I move it backwards twice the distance,…it actually gets a quarter as bright as it was.…Let's go and look…at this in practice and show you three shots where all…we're doing is moving the light in closer or further away.…So our primary shot.…
