Working with a light meter

Abba Shapiro: Now, let's look at refining our lighting setup, making sure that our Key Light and…our Fill Light and our Back Light do exactly what we want them to do.…Now, we did a kind of a pre-setup before, but now we actually have the model in the…shot, and we can see how the different lights will light her.…Now, in this movie we're going to use a Light Meter, but if don't have a light meter don't…worry because in the next movie we're going to show you how to do the same thing using…the Histogram on your camera.…So the first thing I want to do is I want to make sure that my Key Light is at the luminance level that I want.…

So, the trick here is first, when using a Light Meter, depending on your camera, you're…probably going to set your shutter speed to either 1/125th of a second or 1/250th of a second.…I'm going to be using a Canon camera, so I like to shoot at 1/25th of a second, because…in reality, I'll be shooting a lot faster because these strobes go off in milliseconds,…and that's going to freeze my action.…
