WEBVTT 00:00.420 --> 00:05.970 Hey welcome to a new section in the course this section is all about actually how to shoot video with 00:05.970 --> 00:06.850 your camera. 00:07.050 --> 00:11.940 In this lesson we're talking about exposure basically how to make sure your video is bright enough not 00:11.940 --> 00:15.400 too bright or not too dark with whatever camera you're using. 00:15.540 --> 00:20.760 So we're actually going to head out to a real world location where Sam is going to explain how to properly 00:20.760 --> 00:22.420 expose your video. 00:22.590 --> 00:27.450 So now we're going to talk about exposure and really what this comes down to is how much light is in 00:27.450 --> 00:33.450 your frame and we decide to do this in Phil's kitchen just because a lot of times in documentaries or 00:33.880 --> 00:37.020 you know even shooting something for yourself you want to be in a natural environment. 00:37.020 --> 00:41.400 So it comes to exposure light is really what we're talking about. 00:41.460 --> 00:45.170 It's how much light is on your subject how much light is in your frame. 00:45.240 --> 00:50.880 And there's three ways that you control this with a smartphone you won't necessarily set these but they 00:50.880 --> 00:52.440 will be affecting your image. 00:52.440 --> 00:59.670 And for dislodges or merely cameras it's really essential and that's useful to speed your F-stop or 00:59.670 --> 01:02.310 iris or aperture and your ISO. 01:02.310 --> 01:04.090 So the first is shutter speed. 01:04.110 --> 01:08.700 Back in the day you know for old film camera this would be you take a photo and how quickly did that 01:08.700 --> 01:11.310 shutter expose your piece of film. 01:11.310 --> 01:16.800 Now when it comes to film or video Think of every second the shutter is moving up and down allowing 01:16.800 --> 01:22.430 light in a slower shutter speed allows more light a faster speed allows less light. 01:22.620 --> 01:28.210 So currently I'm at one fiftieth shutter speed so let's go a little bit slower. 01:28.230 --> 01:28.660 Oh man. 01:28.660 --> 01:30.140 We're going way over exposed here. 01:30.190 --> 01:32.800 I get the exposure right so I'm up a one. 01:32.880 --> 01:35.330 Let's go one tenth shutter speed. 01:35.400 --> 01:38.590 Now 6.3 ISO 200. 01:38.940 --> 01:42.480 And you know when the image is still you can't really tell the difference. 01:42.480 --> 01:48.570 But Phil if you could go see that the hand is all blurry you can't really see if you're moving the camera. 01:48.570 --> 01:51.410 It has this weird sort of jittery effect. 01:51.420 --> 01:56.850 It can be really cool and this is actually a lot of people do this at nighttime to get a cool of a ghostly 01:56.850 --> 01:57.810 effect. 01:57.810 --> 02:03.730 Now let's bring the shutter back up and I just want to show that movement again at one fiftieth shutter 02:03.760 --> 02:06.130 and this is really what I consider to be the standard. 02:06.360 --> 02:09.570 So you can see there's still a little bit that blur but it's manageable. 02:09.630 --> 02:11.460 It looks more natural. 02:11.460 --> 02:13.680 Now let's go up to let's go crazy. 02:13.680 --> 02:15.950 Let's go to one for hundredth shudder. 02:15.960 --> 02:20.880 And I think this is where a lot of people go out into the day and they need to expose properly so they 02:20.880 --> 02:22.660 bring the other way up. 02:22.800 --> 02:29.720 So not one four hundredth shutter ISO 200 f 2.8 and you can see this a lot less blur on his hand and 02:29.730 --> 02:32.660 it's a much sharper crisper image. 02:32.670 --> 02:37.630 Some people like this effect you know Saving Private Ryan is a great example of higher shutter stuff. 02:37.980 --> 02:41.340 But it can look a little too sterile a little to digital for me. 02:41.340 --> 02:46.260 So personally I like the issue 150 of next is F-stop. 02:46.290 --> 02:48.950 It's how much light your lenses allowing in. 02:48.950 --> 02:51.480 So on the inside there's an aperture. 02:51.480 --> 02:52.920 It's very similar to your eyes. 02:52.920 --> 02:58.110 You know when there's a lot of light you'll have to close down the aperture making a much smaller hole 02:58.350 --> 03:01.170 if you want to allow more light and you open it up. 03:01.170 --> 03:02.920 So we're at two point eight here. 03:02.970 --> 03:05.730 You can see that the background is slightly out of focus. 03:05.730 --> 03:11.680 Fills nicely in focus and there's depth there so let's close it down. 03:11.820 --> 03:17.620 Now to let's see let's go let's go crazy at the level now which for indoors is kind of crazy. 03:17.620 --> 03:21.870 So we'll bring the ISO up and you can see that a lot more is in focus. 03:21.870 --> 03:24.960 You can see the background image you can see fill in focus. 03:24.960 --> 03:30.210 Everything's kind of in focus so this can be great if you're running and gunning or maybe you're trying 03:30.210 --> 03:33.810 to have everything just look nice and frame and everything in focus. 03:33.810 --> 03:39.600 For me personally I love being as open as possible I think having that shallow depth of field is really 03:39.600 --> 03:42.450 the look I prefer but it's different for everyone. 03:42.450 --> 03:47.340 The final thing and really as I've been adjusting all these things you know the show has remained the 03:47.340 --> 03:50.990 same it's about 150 of where 2.8. 03:51.270 --> 03:58.740 But the iso's of the last last piece of this puzzle really what it used to be is it was the sensitivity 03:58.740 --> 03:59.440 of your film. 03:59.460 --> 04:06.030 It was how how well did it perform in low light versus how unsensitive was it. 04:06.050 --> 04:10.960 You know if you went out into the sunlight and needed something that took more light to expose. 04:11.220 --> 04:16.090 So currently I am ISO 250 which is pretty good. 04:16.110 --> 04:20.440 And you can see now let's go up to 16 hundred. 04:20.550 --> 04:22.180 This is as of 16:00. 04:22.290 --> 04:25.890 It's so much more sensitive to light its way overexposed. 04:25.890 --> 04:36.300 I had to bring my F's up all the way to a to look well expose So all these numbers do coincide with 04:36.300 --> 04:39.850 one another to keep it simple it's how sensitive is your camera. 04:40.050 --> 04:44.100 And at that certain cameras performed better with higher ISOs. 04:44.100 --> 04:50.750 The reason the ace of nest 2 is so popular is that you can shoot at these crazy high ISOs other cameras. 04:50.880 --> 04:52.830 Not so much for a smartphone. 04:52.830 --> 04:57.960 The ISO sensitivity really only takes you so far because it's just a smaller camera smaller sensor all 04:57.960 --> 04:59.150 these other things. 04:59.160 --> 05:02.140 So those are really the essentials for exposure. 05:02.160 --> 05:08.700 And as we go into Solarz and other cameras will get more in depth about how you actually expose your 05:08.700 --> 05:13.880 image and how you use these tools because if you're trying to really get serious about film making While 05:13.890 --> 05:18.740 this can seem daunting and like a lot of information it's something important to learn. 05:18.750 --> 05:21.410 And really it's become second nature after so long. 05:21.410 --> 05:23.260 So we'll get to that later. 05:23.400 --> 05:25.680 And now we're going to be talking about composition.
