Flash Settings: TTL Flash Power
TTL. So we talked about manual flash power, but what does TTL flash power look like. TTL flash power is slightly different. So TTL, when the flash fires onto the scene, it gives you basically an exposure. And that exposure is what's called a zero exposure, or a medium brightness exposure. And I always talk about it like this, like, it's like your at a party and a guy hands you the hors d'oeuvre. Here's your unflavored hors d'oeuvre, it's zero, it's in the middle. And you're like, I want my hors d'oeuvre spicier, so you can increase the power. Or I want my hors d'oeuvre, you know, less spicy, so you reduce the power. The camera is always going to serve you a middle brightness exposure in TTL mode, it's going to try to do that. So your job is to say, oh I like the flavor of that hors d'oeuvre a little bit, but I want it brighter. So you take a shot, you know like it's too dark, boom, you increase the exposure on the flash, let me show you how you do that. So, I'm going to go back to TTL ...
mode here, go to TTL, and its got all the BL and the FP and all that other stuff, but I'm just thinking TTL. I take a picture, let's see how the camera does when I take this picture, and I look at it on the back, and I'm like, oh you know what, I mean, it's actually pretty good. I know that it doesn't look so great on the screen there, but on the camera it's great, fantastic, I don't have to do anything. But let's say I did. Let's say I wanted to increase exposure or reduce, so now what I can do, is I just can push my plus and minus button, and I rotate it left, see that number up there? It says EV, does anyone know what EV stands for? She said it, exposure value. Bingo. Exposure value. So zero exposure value, plus one exposure value is actually another stop of light, one more stop of light. Minus one is minus one stop of light. So as I'm taking pictures at an event, and I'm in TTL mode, I just literally take a shot, look at it, and I go, oh that's too bright, I need to reduce power. Take another shot at minus one, you know. And then I just, you know. Take a shot, take a look. That's why I love digital. Digital is so, it makes the learning curve so fast. I remember back in film days, man, I'd be taking photos and I'd have to wait three days to get my film back, it was driving me crazy, because I'd forget. But now it's just real time feedback. So TTL mode, remember, the camera always gives you zero, that's where it starts out, and then your job is to say, I want more than that or less than that.
