Overpowering Sun with Flash
you mentioned high speed sink. And so I did have a number of questions about overpowering the sun. Whether that's using high speed sink or powerful strobe, a question came in from Roger. Do you use the bigger flash to overpower the sun? So could you talk to that? Yeah, that's a really good question. So there's a lot of nitty gritty in here and lighting one on one and two, and we'll get into all the nitty gritty stuff of this. But one thing that's really good to know is when you turn as soon as you put your flash in the high speed stink, you are no longer getting that single pulse. You know, this polls that we talked about, Um, as soon as you go in a high speed sink, what you see instead is this. You see that what's happening is the flash didn't just magically be able to fire, like we know that our sink speeds sing. Speeds are generally 1 2/100 of a second, right? Anything above this, you have to go in a high speed sink. Anything below this that's when the flash can fit a shot. The flas...
h can fit of fire into your friend. If you're below 100 a second Now, when you go into high speed sink 1 401 The flash didn't just magically get faster. It didn't just automatically be able to quickly firing a shot there. What's happening is every step up that you go in your shutter, you're gonna see a couple more pulses. So what it does is it takes this power down instead of firing a peak power right here. It reduces the power toe like, say, 20% and fires a stream of shots, one of which, two of which will land on your subject. So what you see is a dramatic drop in power, right? This goes from if you're at 1 200 of second and you stepping upto 1 8000 of a second, you're going to see about seven stops of light loss. That's crazy. That's like, let's like turning this into that, so it doesn't nothing. So when you want to overpower the sun and use high speed sink, that's very difficult. So generally what we need to dio we need to keep our six feet of 102nd and this is where we introduce nd filters So we know that shooting in the middle of the day if you're shooting a beautiful scene, you're shooting at F 11 because everything is gorgeous. Behind you have this amazing landscape and you put the subjects in their It looks incredible. F 11 is great. It's a good place to be right. But if you're shooting a place where you don't necessarily want that depth of field, maybe you want to shoot more shallow, you run into the problem of your shutter speed. We're running up there when you're shooting during daytime. So using nd filter and grab one of these guys, this cuts amount of light down coming in the lens by. Well, this is a four stop. Is the three stop? Actually, So this is a tiffin three stop water White Square filter, and what I'll do is I'm kind of lazy like that. So sometimes if I'm shooting on a tripod and I want to get the best out of my images, yes, I will screw them on or mount them onto the lens. But if I'm just going quickly doing portrait's, I'll just hold this directly over the lens. This will let me drop my shutter speed, get a good image at a shallow aperture. I can shoot a F two and still have 1 to 1 of a second for my shutter speed in the middle of a day. Cool. So that's where the end Andy Field comes in. Now you say this is where people get again. Tricked up a little bit. Does the nd filter effect flash or ambient light? Who thinks both. Who thinks Ambien Onley? Okay, you guys are so bold. I love it. I love it. None of you are wrong. Everyone's right. I'm just kidding. Everyone is right. It doesn't affect both. That's where we get mixed up. A lot of people think that this is gonna affect. And I think the a couple of guys that raise their hand knew because they were in my last class. So yeah, okay. But anyway, it's cutting down all light. So all light is being reduced by three stops on this guy Flash firing its darker ambulance. It's darker. It's all being reduced. The differences At 1 2000 of a second, I'd probably be losing 56 stops on this guy. But at 1 202nd I'm only losing three stops with this guy. So this allows you to get more power out of your pocket flashes.
