Ready to learn how to use a light meter on outdoor location portraits? Let’s get to it.

This has been your most requested video, is how to use a light meter outdoor. Now, I would know what you might be thinking if you’re just tuning into this, why do I need a light meter outside? Well, it’s to use flash on your outdoor photo shoots. I’m going to show you how to take your ambient light, reading your natural light and incorporate flash to get the look you want, from blending with the natural light to a more dark, moody portrait, which is something that I’m known for. But I’m going to show you how easy it is to do with this tool right here, that many of you are paralyzed by, a light meter.

All right, let’s get started. Let’s have some fun. So the first thing we’re going to do here is if you’re using your light meter, and we’ll show you closeups of this, first thing you’re going to want to do is put your light meter not in flash, but you’re going to want to put it in ambient light mode. You’re going to hit T which means we’re setting the shutter speed and setting the ISO. I want to know what my F-stop is. So I’m setting my shutter speed to 250th of a second, ISO 200. Then what I’m going to do is I’m going to take a meter reading here, which means that the light coming in here is coming in at 284. That’s what she’s being lit with.

So I now know on camera I’m going to F/2.8 because we already know that’s the ambien and I’m going to match the ambien, and you can see the difference between a darker moodier portrait and one that matches more with the ambient. Okay, so now you might be thinking, well, if it’s matching with the ambient, why use flash at all? I don’t want any shadows on her face. I want to have beautiful even lighting on her face so that flash can just be a pop of fill or something like that. But you’re seeing the thought process in how we went. So we already know at F/5, this is giving me 5.6, 5.6 to 4.0 is one stop. 4.0 to 2.8 is one stop. So in theory, because these work in full stops, I should just go from five to three and I should be damn close.

Test Shots

Settings: f/2.8 @ 1/250, ISO 200
Settings: f/4.0 @ 1/250, ISO 200
Settings: f/5.6 @ 1/250, ISO 200

So let’s test it out. I’ve changed the power to three now and I’m going to meter her and it should be at 2.8, which is what we want. Now remember, you might be thinking, well, the natural light is two eighths out, so of course it’s going to meet her at 2.8. No, it’s not. I’m in flash mode on this, not ambient. So now I’m going to measure this. Okay, 4.01. Sorry, I got to come down one more. Maybe if I learn how to count. 2.8 test. At 2.8, you’re seeing the shot that looks completely balanced with the background, same brightness on her in that background. So that’s something that you want to start seeing and understanding on how to balance the ambient. So some of you may like that look, but notice on this, if I zoom in here, the shadows are just perfect on her face.

Now of course, Marilyn doesn’t have deep set eyes or anything like that. But let’s say you did, let’s say you had a client with deep set eyes in this type of light, even though there’s no direct light in here, they’re going to get those kind of raccoon eyes. You would balance your flash with the ambient, the natural light, just to give them a little pop in their eyes and bring their eyes to life, so that they have those catch lights. That’s what we’re able to do with this. Now, personally, this is not what I like. I like the darker background and them popping off. So I’m going to get back to that and we’ll show you some final images when we’re all done.

Hopefully this gets you guys going. Like I said, it’s your most requested video. Like, comment, subscribe, and we’ll see you in the next video. I got to get back to work.
