Shutter Speed

Shutter speed is exposure, of course it's going to affect exposure. And then of course movement, both the camera and the subject. So it is considerable simpler. Shutter speed goes up two stops, you've gotta compensate, again, just to remind you, with something else. In this case, ISO went down two stops. That's to maintain accurate exposure. 'Kay, same thing, shutter speed goes up two stops, you have a choice, you can drop aperture and ISO as well. What does shutter speed affect most? Well, it's moving subjects. So, this is a little chart here of different... Effects on the water at different shutter speeds. Basically I've realized over time that I do want some detail in moving water. I don't just want a white misty, like you see here, two second exposure doesn't have as much detail basically. So, I love an 1/8 of a second, 1/4 of a second. Kinda depends on how much moving water there is, how far you are from that moving water. Okay. Now, it also is affected by ISO because ISO can only...

go so low. So, if it's too bright out, and you wanna maintain your aperture and you shutter speed, that's when you want to put on your filter. That's the scenario that matters. 'Cause remember, you want 1/8 of a second, or a particular shutter speed, and you need that depth of field, and you're locked at your ISO. So that's when you'd put on a neutral density. Then you'd lose that stops of light with the filter, rather than the other two elements of the trinity. And then ISO, ISO's similar. Same thing, you increase ISO, you've gotta compensate with either shutter speed or aperture or both. The higher the ISO, the less useable dynamic range. Now, theoretically and on paper the dynamic range is the same, some people debate that, but essentially all that mattes to me is what's usable in the picture. And so I've shown a little example here, or, before that, sorry, the dynamic range is the range of tones between the brightest and the darkest, that maintains detail. Just to reiterate that point. And you can see here in this shot of my studio. Up in the corner there's a lot of, same as that other example I showed you, there's a lot of noise, and so that's getting in the way of the details that's there. So in my opinion, that's not usable detail, therefore it's really not part of my dynamic range that I want to consider when using that ISO. This is really important when you're photographing at night. And stars. And so a couple of examples, I mentioned earlier I have a blog post coming out about this exact test that I did to find one of the better low light cameras. This is just showing you some examples. It' a little hard to see on the screen, but the Sony a7s, at 6,400 ISO versus 51,000 ISO. It's hard to even say that, 'cause it wasn't too long ago we couldn't conceive that. And then to make things even more interesting, this is the Pantax Medium Format camera at 51,000, versus 204,000 ISO. Which is just amazing. But you can see you're compromising at that point, some of the detail. And I'm exaggerating that here, just so you can see what's happening. So, when you compromise what. In this case we're gonna walk about compromising dynamic range and noise. Why? Because we want to photograph at night. So these night pictures aren't gonna look as clean as the daylight pictures. But it's night, it's incredible. We can deal with that compromise. It's worth doing. Right now it's amazing we can even take the pictures at night. So you'd also compromise probably the same two things, because it's the Milky Way. It's not just night, you're getting the whole entire Milky Way, it's worth making that compromise. And then another example is compromising diffraction for sunstars. So when you stop down, yes you're losing some sharpness and detail, but you're gaining the beautiful rays of the sun at sunrise, and wherever you put the sun. And then diffraction by depth of field. So it's not just for sunstar, but also in the situation, and most situations in landscape, we have to compensate by using a depth of field so that we get that foreground in focus and the top of the mountain in focus. So, the other one that I'll suggest is your creative freedom. You know, when you're thinking about these things you want to increase the ISO, so that you can go off the tripod, and be more creative with your movements and your compositions. 'Cause sometimes you just have to get your feet wet on the beach on the sand, so that you can find the shot that want, without the tripod. Alright, and to kind of sum things up here, I give you a tip, don't forget to modify the "in camera" playback option, so that you get that full RGB histogram. 'Cause it's different than just the one chart. It'll actually show you a red, green, and blue. And that's important when you're evaluating this. And then an exercise is shoot moving water at every shutter speed between a minute, and 1/60 of a second. You're gonna have to use a filter to do that in most scenarios in the daylight. But wait there's more. I also suggest any new camera you get, or any camera you have, take a picture, even inside, of every ISO. 'Cause it'll give you a good mental picture of how much you want to compromise, what ISO you don't want to use. I've got a couple questions I think. Maybe lets take like five minutes for questions, that okay? Sure. That's fine with me. Let's see what the best one is. Do we have any from here in the room? We covered a lot, anything you guys wanna ask about? Yeah, let's go down ahead and pass you the mic over there. Are you able to use auto focus for the hyper focal distance? Or is that pretty much a manual focus situation? Well you could certainly use the camera in auto focus. And as you move that little square around in live view, then you can focus on that point. So yes, you can use auto focus. You just have to move that square around where it focuses, and have a camera that does that. I don't know what camera you're using. Some of them do, some don't. They had a feature in old Canon Elan, it was the best thing ever, but it actually did this for you. You hold the camera up with a single point auto focus, click down, it registered that point, which was infinity. Then you pointed it at the next, which was your foreground, clicked again, and the third time you pressed down on the shutter, it set that. Why they did away with that, I don't know. But anyways, that's essentially what you're doing with this test. RSCCMS84, and one other person wanted to let you know, "For the record, Canon does have a menu tool "for controlling highlights. It's called highlight tone priority." So, for anyone out there using a Canon, that is information for you. Very helpful, thank you for sharing it. Very good. Also, we've got Bridgette, who wants to know, "Why do you change to aperture mode, "why don't you stay in manual mode?" And I'll extend that to ask, in what situations do you tend to use the different shooting modes? Yeah, so typically for handheld, I'm going into aperture priority because it's one less thing I want to think about, which is the shutter speed moving around. So it really just clears up my mind because I'm not on a tripod. And that's probably the main reason. And in that same vein, it's also when I'm photographing something moving really fast. Wildlife, 'cause a bird can fly from a shadow to a highlight just like that. And there's no way I'm gonna be able to compensate that fast. So aperture priority really works. In that scenario, maybe a bird in flight, I might change to shutter priority, so that I maintain the shutter speed ane have the aperture fluctuate. Let's go to Photomaker, "Do you just leave your white balance setting "on auto for your landscape shots, "since you can adjust the wrong post?" Do I leave it at auto? Yes, 90% of the time. Occasionally I will change for the night photography, just to get a visual on the back of the camera, of what it might look like. It's a little better if the auto, white balance doesn't work too well at night, so in that scenario I'll pick a white balance of 3,800, thereabouts, for the night shots of the Milky Way. Other than that, auto white balance works really well. The only caveat to that is that if I'm shooting video, the camera shoots video real well, and it's really fun to shoot video, but whatever white balance is set, it will remain on that video. So you wanna double check white balance if you're shooting video. Great. Any final questions here? One more, go ahead. Yes, I was wondering how you utilize or evaluate the RBG histogram? Okay, the RBG histogram is really just the same thing as the white one, where it's projecting all three. So what will happen is typically one of the colors will shift first, and so you're getting a more detailed view of those tones in that color channel. So the camera really projects JPG file, so it's not the raw file either. So what you're looking at is to just, you might want to fudge to the conservative side, and that gives you a little more information. Sometimes it could be a blue channel for a sky. You never know. A sunset might be red, is peaking over there towards the right. So, that's what you're looking for.
