Controlling power output

Once you've made your determination about shutter speed and aperture, it's time to actually start tweaking the lights to get the image to look the way that you want. And each of these lights have a power setting and they're going to be putting out at a certain wattage or F-stop. So, one way to do this is simply take a test shot, and look at the image and see if you like it. And then tweak your lights based upon that. So I'm going to simply go in, I'm going to zoom in to Valerie here. so, I look at this image, and I can see that the light coming from the right side is way too bright.

The left sides not bad by comparison for my aperture but I want to start doing some adjustments. So Rich let's turn down the brightness of the octobox and one of the things I want you to take into account is we do have modifiers on some of these lights, actually on all of these lights. Later on we're going to be showing you how each of these modifiers work so you'll be comfortable with them. But for now, just setting up how bright the shot is, and how bright the lights are and just turn up the brightness, or turn down the brightness.

>> I'm at 6.5 >> So you brought it down to 6.5, and it was what before? About >> Ten. >> Ten, that's definitely all the way to the top. We'll take a quick shot here. And, as you see, this shot is a lot more balanced. Her skin is not blown out. I think it might be a hair dark, so let's tweak that up to seven. And we're going to fix a couple of other things. At this point, I also notice that Valerie's blending in to the background, it's a gray background, dark dress, she's fair skinned. Let's go head and turn on the background light and just throw some light onto this grey area which will make it pop a little bit.

And, we'll do a test. So, as you see now, there is a lot more separation between the back wall and Valerie. She pops a lot more. my light's not too bright, but I think I want to move that light a little bit more behind her. So I'm going to have Rich pan it to the left and he might even need to move the diffuser a little bit to the left just to make sure that we don't have that really bright area to the right and too much fall off to the left of the image. Let's do another quick test. So I like this shot a lot better, it works for me.

I'll probably do a little bit of tweaking afterwards, but I think I'm ready to shoot. Now when I'm testing the light, whether I'm working with a model, or I'm working with an executive or a family or even a still life, while I'm tweaking the lights I don't need them to keep posing and smiling, I just want to make sure everything is balanced. So, take the shots, let them sit there relaxed, you want to see how the light reflects off their skin, and once you get things balanced, then you can start working with poses and positioning.
