Shutter Speed: Time & Motion
All right so we're going to start by talking about shutter speed and I like one explain this I like to compare it to our eyes because we have experience with our eyes right we've had them our whole lives so we know how they operate so if we were going teo compare our eyes with a camera what part of our eyes do you think would be like our shutter speed anybody I guess you need a microphone if you're going to talk somebody don't leave me hanging here come on your eyelids here I let biggio your sunder speed would be like your eyelids so we can change how quickly the camera blinks basically so the by default of course when we're just standing around not taking a picture of the shutter is closed when we press the shutter button it's goingto blink open and then blink back shut again and shutter speed controls how quickly it does that the effect that that has on our image is that shutter speed will affect our time and motion the way that time well that motion really is captured in terms of ti...
me on our on our exposure so for example if we're taking a picture of somebody running really quickly if we want to freeze the action we would use a faster shutter speed so the cameras blinking really quickly right so when the camera's actually seeing it's only seeing such a small sliver of time that the person running just appears in one place in that instant but the camera blinked if we leave the shutter open longer so it's a slower shutter speed then the camera's going to see the person actually moving and that would be recorded as a blur so when you think about it shutter speed is really you're controlling how long of a photo you're taking which is kind of funny because when we think about taking photos we think about it's a it's a moment captured in time which it is but your shutter speed controls how long of a moment you capture so you can have like ten moments and one it's like a moment with a second you could have ten moments in one picture if your shutter speed was set that it was open for ten seconds does that make sense so let's see how the shutter speed is it measured these are this is not an extensive list of shutter speeds by the way it's just sort of ah random assortment so there are additional options beyond what I'm just showing you here but this is just to help you understand the continuum of how it works shutter speed is usually depicted in fractions of a second for example, one five hundred of a second on dh then of course if we get slower we might get down to one thirtieth of a second maybe a whole second maybe thirty seconds maybe two hours maybe who knows that can go on pretty indefinitely this way on dh then of course it can be faster to sew on my camera it goes as fast as one eight thousands of a second that can vary from camera to camera so you just have to kind of see what your camera khun dio as your shutter speed get slower motion will start appearing as a blur in your picture right because your camera's having its eye open for long enough that it's seeing motion happen so you'll start to see that and the faster the shutter speed is going to free the action so we see that down here all right? So let's see some effects of that so here we see a frame where we have some motion blur so that be shot with a faster shutters theatre a slower shutter speed floor shutter speed right? And I think it's important by the way when we're talking about these concepts don't worry about the actual shutter speed people sometimes get really caught up in like well, what were your camera settings? And I want you to release yourself from those super tight details and think more big picture and just think with that fast shutter or a slow shutter okay at least for now so this you're right this would be a slower shutter because we're seeing motion there here's another example faster or slower shutter faster shutter, of course, because we have some action frozen here. Now, what was the exact shutter speed on this? I am not sure I even remember to be honest, but how fast is fast enough? Depends on what you're shooting. This could be shot at one eight thousand of a second. He would be frozen and I'm pretty sure he could have shot us that one five hundreds of a second, and he'd still be friends, right? So the exact number is not as crucial as just knowing in your mind. Are you looking for something faster or something? Slower to help you accomplish whatever you're trying to do. So let's, talk about this, I guess I don't know that you guys have your cameras with you, but folks at home that might have your cameras with you, I want to show you how you actually control this stuff on your camera. Of course, it's going to vary from model to models, so please don't hold me responsible for memorizing every make and model of all the cameras out there. I will refer you to your manual, teo, find the specifics, but to adjust this stuff, of course you want to be in manual mode, so for a lot of cameras, you've gotta dial somewhere around the top of your camera and it's got a whole bunch of alphabet soup going on up. There are lots of different letters and pictures and things you would want to dial that so that your cameras set to em that will enable you to shoot in manual mode to control your shutter speed. Then on many cameras, it's going to be the style over here, so usually it's pretty near your shutter relief button on dh you can spin it one direction, and then you can spin it back the other way and it's going to adjust the shutter speed and you'll see that in several places, notably here on the top of your display, but you'd also see it. When you're looking through your viewfinder, you have some numbers, probably their green. Now that I think about it, I'm not even sure yeah, so there's some numbers down here, the bottom of your view when you look through your viewfinder and perhaps you've been ignoring them your entire life now is when you want to start paying attention because they're actually really useful and they're telling you stuff like what? Your shutter speed, is it on a point in shoot camera if it has a manual mode? You'll have to look up how you would do this because again they're all so different but for example, the pointe shoes that I had that I love had a little ring on the back here that I could spin around and choose my shutter speed when I'm in manual mode let's talk about what we see when we look through our view finder we're going to see our image area here and whatever were whatever frame were composing and then down at the bottom there's all kinds of numbers and yours of course might look slightly different they're all interpret this a little bit differently but it's all actually the same thing, so somewhere down in you're the bottom of what your viewing you're going to see something that represents your shutter speed. Now we talked about that a lot of times unless you're doing a really slow shutter speed so that it's like a full second or more you're going to be working with fractions of a second, but the display doesn't put the fraction part there because they just want to confuse you, ada because it takes up too much room. I don't know because you can't do fractions in whatever kind of thought that is um calculator display uh you just have to know in your head that when you see five hundred that doesn't mean five hundred seconds long that your camera is going to be open it means one five hundredth of a second so this is their fraction ok alright, so thats that so folks at home who want to give this the world I would invite you to put your camera in manual mode figure out where your shutter could your shutter speed dial is and then just dialled out around and see what your outer limits are and you'll notice when you're doing that once you scroll slower than a fraction of a second like if you get to a full second and even slower, you will probably see that depicted with inch marks. So for example, if I die, I'll mind down to be like a thirty second exposure it doesn't just say thirty it says thirty and then it has like quotes so it looks like thirty inches. The quote the inches actually means seconds, so we've got we've got the non fraction that's, the fraction and the engine that is the second got it kind of silly, so I guess my my challenge for you here would be figure out where you control your shutter speed and then go to both extremes so you can see what your cameras capable of my camera goes from thirty seconds all the way tio one eight thousand just for a perspective, but every camera is different, so take a minute folks at home and give that a world
