Adjusting Flash After Setting Up Ambient

I just want to actually go back because I saw some follow up questions back to the beginning of this segment and make sure that everybody home understands you were showing us how you set up for the ambient light. Start your exposure there. Michelle had asked. So tell me again, What do you do after you set up the Ambien? And then what do you do for the pop of like, How much? How do you know how to set that flash? How do you know? What the exposure You think we have time for a quick demo or we have three minutes. Probably haven't eso. That's really just the last factor in your you know, like when you if we have three minutes, Aiken drawn this board for three minutes. I like sports. Okay, because said that plenty. So in the equation, we have this right. We dio aperture. I s O hopes shutter eso Rumor, white balance and flash. Well, think about it. If you're teaching the courses that you're always gonna dial these items in for the kind of compositional effect that you want remember going ba...

ck to your story the purpose of an image. Okay, So we choose these on how we wanted to look when we get these things all dialed in with flash, you have just one variable. And I want everybody to break it down like that simply And just think about this worst case scenario. You've already figured out how much light you wanted. Everything else your subjects dark. Just start somewhere, just like literally. Just say I'm gonna put this at 1/4 power and just see where your light is. Okay? Here's a simple rule of thumb on flash power that gets can use when using direct flash, Just at least to get you close to somewhere, right? Let's say I so 100. Okay, start it. 1/1, 200 start at 1/2. 400 started. 1/4 800 started 1/8. Now, obviously, this depends on distance, and it depends on how you're modifying and all that kind of stuff. But it's a simple rule of thumb to at least get you not scared of where to start out at that. I mean, so you can start somewhere. Now keep in mind that anywhere between 1600 to 3200 is so if we're popping off. Direct flash were usually around 1/16 toe, 64th power. But that kind of follows the rule, doesn't it? Kind of. It's pretty simple and straightforward, and from there you might have a one adjustment, two adjustments. And that's not a big deal. If you need to adjust once twice to get that flash to the right power. Just remember that when you defuse, keep this rule in your head. Okay, if you diffuse with like saying umbrella a soft box, cut your light. So if you were shooting at 1/8 power and you start diffusing, I want you guys to go at least two stops, even three stops up. OK, so basic rules of thumb to just kind of give you a place of where to go, because you're gonna have 2 to 3 stops of light loss, depending on the type of diffuser that you're using and distances. You're so much pie. I think that that's what happens for a lot of us. And new photographers are working with light that the need time is like not even having that ballpark of where to start and then sort of freezing. And that's what we get paralyzed because we think of this whole thing together and we really shouldn't. We should think of them as two separate things. You start here based on what you want, compositionally you work into your flash last, and that's the only thing that you're adjusting at that point.
