Want an Easier and Faster Way to Calculate the Exposure Formula?

Sometimes math is fun (and filmy). Exposure: it's the very foundation of your image. So much effort and technology go into making sure that you, as a filmmaker and camera operator, can achieve the desired exposure for your images, and balancing the three factors that make up the Exposure Triangle, aperture, shutter, and ISO, can sometimes make that process a bit of a pain. It gets especially tricky if you have a specific f-stop or combination of the three factors listed above that you want to use because you'll have to calculate the Exposure Formula to figure out how much light you need. Or, conversely, if you have a certain amount of light, you'll have to calculate what f-stop you'll need to use to expose your scene "correctly." (Of course, you can expose your image however you want.) If you're a little confused by these concepts or are tired of doing all the math, Matt Workman of Cinematography Database just might become your best friend today. In this video, he does a great breakdown of each of these concepts, as well as shows you how to put together a nifty Google Doc that will do all of the calculations for you automatically.
