Camera Setup: Exposure Mode
So I talked about metering mode, right? So that's the light meter. The light meter is the thing that measures the light on the scene. Next is the exposure mode. So most cameras have four exposure modes. So we have, let's see, program mode, that's the letter P. And I'll turn the camera here this way so the house cameras can see it. So these are my exposure modes here. P, S, A, and M. That's on the Nikon. On the Canon, you've got AV, right, and TV. What does AV stand for?
Aperture priority or aperture value. And TV on the Canon? Time, time value, so shutter priority. Okay, cool. So, P, S, A, and M. For me, when I do flash photography, I only choose either aperture priority mode or manual mode. The other modes I don't find as much use for in flash photography. So, let me explain why. Or let me explain why you would use either of these modes. Starting with manual mode, and I'll rotate this to manual mode so you can see this, so I'm in manual mode now. In manual exposure...
mode, nothing changes, right. Your aperture stays the same and your shutter speed stays the same, regardless of what happens. So, another term for that is consistency. A lot of times when you're in the studio, like we are here today, we're indoors, you just want things to be consistent. And things are consistent, you know, the model doesn't move a whole lot. Your tripod and your camera typically stay in one location. Maybe you're changing lights from here to there but for the most part things aren't moving so you kinda want to just lock everything down. You want everything to be consistent. So that's a good, a great hint for you. When you're in the studio and time is on your side, I highly recommend manual exposure mode. It allows you to take a picture, look at the problems with it and then think, "Oh, I need a little bit longer shutter speed, you know, to get the house lights." "I need a little faster shutter speed to reduce the house lights." Manual just lets you kind of methodically move through your lighting arrangement. Aperture priority, that's where you set the camera for A or AV depending on your camera model. That now fixes the aperture in your lens. Let me take this lens off here and just show it to the camera. I think you can see it this way. This is the aperture and the aperture opens or closes depending on what you choose in the camera. So like wide open, that's like F 1. and all the way closed, that's like F 22, okay? So in aperture priority, you're gonna pick, let's say F8 and the camera will always stay at F8. Now, the shutter speed thing, who chooses the shutter speed? The camera. The camera chooses the shutter speed. Well, this is a little dicey because as we're going to learn in a little bit, the shutter speed really matters, right? The shutter speed really matters in flash photography. And most flashes that we own will not synchronize if the shutter speed is too fast. So we have to be thinking and making sure that the shutter speed doesn't go above some threshold and it's different for every camera and I've got a slide on that in a little bit but in general, it's around a 200th of a second. So you don't want your shutter speed to ever go above a 200th of a second otherwise you may have problems getting flash onto your subject. And sometimes you'll get this funky look to your photography like half the frame will be lit up with flash and half won't and trust me, those photos don't sell very well, just not at all. So, aperture priority mode sometimes is problematic because you don't always have control over that shutter speed. And so that's why for a lot of flash photography, as the years go on, I tend to default more and more to manual exposure mode. That's where you have full control over it. And there's nothing to be fearful of in manual exposure mode. I'm going to show you today how I set up these shots and you'll go, "Oh, that makes sense and now I understand why he choose a 60th of a second or why he chooses a 200th of a second. I can do that too."
