WEBVTT 00:00.720 --> 00:01.410 Welcome to. 00:01.410 --> 00:02.880 Good source material. 00:02.880 --> 00:04.910 Now what do we mean by source material. 00:05.100 --> 00:11.370 Well like reference material in the past but this time it's actually going to be used with in our final 00:11.370 --> 00:12.670 render. 00:12.690 --> 00:18.690 So this could be a picture a photo a video or even another render that you've done now in a bit we'll 00:18.690 --> 00:21.750 grab a photo and check out its settings. 00:21.750 --> 00:26.670 Now this is important for both still some photos and I'm going to hammer this point home because it 00:26.670 --> 00:30.640 really does save you a lot of time with your own video. 00:30.660 --> 00:34.830 Keep notes of the settings as they're often lost. 00:34.830 --> 00:37.350 So what device you took it on. 00:37.380 --> 00:39.960 In fact let's get to the essential data that you're going to need. 00:39.960 --> 00:42.740 Now this is a little bit of a white lie. 00:42.810 --> 00:45.670 You can get by without this information. 00:45.690 --> 00:51.840 However it will take a lot of your time and to ing and fro ing and trying to get the scene just right. 00:51.840 --> 00:55.170 If you've got the data it can speed up things a lot. 00:55.410 --> 01:03.040 So the resolution of the recorded data the camera sensor size and the lens focal length. 01:03.060 --> 01:07.520 Now some of these you're going to have to look up for certain devices and some of them are built into 01:07.530 --> 01:14.050 blender so we can use a combination of research or just a preset that's straightaway available to us. 01:14.250 --> 01:20.310 Now pictures fortunately often have this data stored with them and you can right click on them and on 01:20.310 --> 01:25.050 a Windows machine you can go to propertys or on a Mac you can go to get info. 01:25.050 --> 01:30.990 And if the picture has this information stored with it then you will actually be able to look at that 01:31.080 --> 01:32.330 and recall it down. 01:32.340 --> 01:36.510 And then we can set up our camera in the scene with the same settings. 01:36.510 --> 01:41.790 Now if it's a render that you've already done you have to use the camera settings that were in that 01:41.790 --> 01:43.740 other blend file. 01:43.740 --> 01:47.280 Now things that are nice to have is a way before we move onto that. 01:47.280 --> 01:48.580 I do apologize. 01:48.600 --> 01:52.920 Pictures do have this data still with them but videos do not. 01:52.950 --> 01:59.040 So it is a great idea that you know down what device the video of the video was recorded with. 01:59.130 --> 02:02.090 If that's possible now Nice to have. 02:02.100 --> 02:07.530 Well measurements of the area you're working in that's very useful for working at distances and placing 02:07.530 --> 02:12.930 things at a certain scale within your scene position of any lighting. 02:12.930 --> 02:19.110 Now if it's an outdoor scene in the daytime there's usually one prominent light that is the sun in the 02:19.110 --> 02:22.220 sky that will be the source of most of your lighting. 02:22.230 --> 02:27.670 However if it's in endorsing you may have several lights scattered about contributing to your scene. 02:27.780 --> 02:32.940 If you'd taken note of where those are and perhaps the intensity of them or just say they're all the 02:32.940 --> 02:33.590 same. 02:33.870 --> 02:39.100 Then at least you got a good standing to start using that photo or video. 02:39.120 --> 02:44.400 Now in this particular instance we're going to use a photo so the lighting is probably just going to 02:44.400 --> 02:45.200 be the sun. 02:45.240 --> 02:47.080 Keep things simple remember that. 02:47.100 --> 02:48.810 Now a couple of things to look out for. 02:48.840 --> 02:51.540 Light direction and looking for shadows. 02:51.540 --> 02:56.040 Now the can't go hand in hand in shadows can be both a blessing and a curse. 02:56.190 --> 03:00.600 So you will want to make sure shadows don't cross over where your object will be. 03:00.600 --> 03:04.430 If they do you're going to have to create a nother object to cast. 03:04.460 --> 03:07.950 That's the real shadow on top of your objects. 03:08.100 --> 03:11.950 And of course delete the other one and this entails more and more work. 03:11.970 --> 03:15.660 And we want to avoid getting too nitty gritty at this point. 03:15.660 --> 03:21.510 Certainly there will be instances if you ever go into this fully where you will have to edit the actual 03:21.510 --> 03:25.060 picture or video and cut things out and mask things off. 03:25.320 --> 03:29.230 But we're not going to go quite that deep dive in this section. 03:29.250 --> 03:31.890 Reflections are very similar to shadows. 03:31.890 --> 03:35.030 They can give away the true nature of a scene. 03:35.170 --> 03:37.950 So we do have to be careful with their reflections. 03:37.950 --> 03:41.640 Instances like that could be a glass building or a mirror. 03:41.670 --> 03:47.610 A good reflective surface cars tend to be reflective they're going to reflect the area around them things 03:47.610 --> 03:53.400 that you might not focus on like a puddle on the ground those can reflect and give away the fact that 03:53.460 --> 03:56.420 hang on a minute there should be a reflection of the objects in there as well. 03:56.430 --> 04:01.420 Again if we can avoid those type of things we can get on really well and quickly. 04:01.430 --> 04:02.430 That's the important thing. 04:02.430 --> 04:07.980 Now you also have to watch out for anything in the foreground those foreground objects can cause you 04:08.250 --> 04:13.960 a bit of a nightmare there in front of your object and therefore you've got to work around them. 04:13.980 --> 04:18.870 So at the moment I would avoid foreground objects where possible. 04:18.870 --> 04:25.470 So finally if you were creating your own source material you can have a bit more control over how it's 04:25.470 --> 04:26.130 looking. 04:26.130 --> 04:31.800 So with photos take measurements of the scene that's very important as well as the camera settings that 04:31.800 --> 04:33.540 you currently have. 04:33.540 --> 04:38.700 So remember what focal length you've switched your camera so if it's a fixed length camera you may have 04:38.700 --> 04:45.450 to research if you've taken a video or photo with your iPhone or Android device then you'll want to 04:45.450 --> 04:53.850 look up the specs of the camera with videos you can lay down markers especially if your CGI is going 04:53.850 --> 04:59.640 to cover the area in question and that can help massively high contrast is. 05:00.470 --> 05:04.400 Because that helps with camera tracking and we'll see that later on. 05:04.850 --> 05:08.460 Now you will want to avoid sharp and jerky movements. 05:08.540 --> 05:14.210 It makes tracking the camera really really difficult and time consuming. 05:14.240 --> 05:21.400 Now remember this the last I'm going to say this is so many times to store your camera and lens settings. 05:21.500 --> 05:23.320 Make sure you know what they are. 05:23.330 --> 05:25.700 It's going to help you a lot. 05:26.090 --> 05:32.050 Okay so now we've got the ground work sorted for what source material is ideal to be working with. 05:32.180 --> 05:39.080 It's time for a challenge and I'd like you guys to go find a photo now find yourself a suitable photo 05:39.080 --> 05:40.250 to work with. 05:40.250 --> 05:44.570 Think about your projects what you're working on and what you are trying to achieve. 05:44.570 --> 05:51.200 Remember please keep things simple especially if this is your first time doing any visual effects. 05:51.190 --> 05:56.840 Now I'll personally be finding a runway because I'm doing a CGI plane and I'm going to place that on 05:56.840 --> 05:58.250 the runway. 05:58.250 --> 06:01.580 Now make sure your image has camera details. 06:01.580 --> 06:07.520 Now if you've gone off and taken a photo great you're going to have all the details because you've actually 06:07.520 --> 06:08.990 taken the photo. 06:09.000 --> 06:17.000 But if you haven't and your sourcing a photo from online make sure that it does have those camera details 06:17.000 --> 06:18.470 embedded in it. 06:18.470 --> 06:19.080 Go ahead. 06:19.090 --> 06:22.080 Pause video and go find a suitable photo. 06:24.380 --> 06:25.090 Okay guys. 06:25.100 --> 06:26.020 Welcome back. 06:26.150 --> 06:29.080 Let's go see what I found and make sure it's suitable. 06:30.170 --> 06:35.510 Okay so after searching the web for a bit I have found a picture I really like. 06:35.510 --> 06:39.980 We can see where the light sources is the sun and it's just dipping below there. 06:40.130 --> 06:41.890 The mountain top they're just glaring out. 06:41.900 --> 06:45.900 That's going to give us some new lovely warm colours as well. 06:46.230 --> 06:49.980 Going to produce long shadows when it's so low on the horizon. 06:49.980 --> 06:54.330 And now I don't have to actually be this but I will since I'm on the site. 06:54.460 --> 07:00.140 But before I go any further of course let's just make sure that this particular photo is suitable because 07:00.140 --> 07:03.070 I don't know any of the settings it might just be an image. 07:03.310 --> 07:06.180 Okay so clicking download has just opened up for me. 07:06.190 --> 07:09.410 A nice high res image that's very useful. 07:09.470 --> 07:11.000 Look at lots of detail. 07:11.420 --> 07:17.620 Okay so I'm going to right click and save the image in my downloads for the moment and open it up. 07:17.620 --> 07:18.730 Now you will. 07:18.890 --> 07:24.800 You can right click on the download itself and get to Properties out or indeed right click and go to 07:24.800 --> 07:25.490 get info. 07:25.490 --> 07:31.060 I believe I can get info from preview on a Mac as well so we can see straightaway. 07:31.060 --> 07:34.410 I'm going to go to the file tab first of all we've got there. 07:34.410 --> 07:39.410 Of course we've got a number of pixels it is that's also easy to look up so that's a great start. 07:39.470 --> 07:42.350 I'm going to look under the E X I left later. 07:42.650 --> 07:44.380 Now this should give us. 07:44.390 --> 07:45.790 Here we go focal length. 07:45.800 --> 07:49.280 So we've got the VAT's we need to know what camera it was taken on. 07:49.280 --> 07:52.560 I'm guessing it's taken on a camera yet. 07:52.610 --> 08:00.680 We got the lens model here now that can be very useful if you chanty exactly mimic a real life lens. 08:00.680 --> 08:03.540 Because we are going get the data for that lens. 08:03.620 --> 08:08.150 If it's got any particular distortion but do we have the camera type. 08:08.150 --> 08:10.520 So let's go along here. 08:10.550 --> 08:11.260 Here we go. 08:11.380 --> 08:14.920 A e e o s eleven hundred d. 08:15.380 --> 08:19.080 I don't know the sensor size for that sungura Search for Canon. 08:19.100 --> 08:22.940 E o s eleven hundred d. 08:23.460 --> 08:25.790 Umm let's give a literally go sensor size. 08:26.000 --> 08:28.250 Now I'm I'm a bit of a photographer. 08:28.250 --> 08:35.370 I'm going to assume it's there a S P A This one here of that size so it's a width here. 08:35.380 --> 08:37.890 Is going to be 22 point two. 08:38.010 --> 08:44.660 So I've written down all of these bits of information making sure that I can go back to them if I need 08:44.660 --> 08:45.050 to. 08:45.080 --> 08:47.160 It's quite an affordable camera. 08:47.180 --> 08:47.880 Excellent. 08:48.080 --> 08:51.350 I really like this photo I am looking forward to working with it. 08:51.350 --> 08:52.490 How did you guys get on. 08:52.490 --> 08:56.260 Are you going to use the photo that I've got here or are you going to follow along with a plane. 08:56.300 --> 08:59.060 You could you could put a car on there if you wanted to as well. 08:59.060 --> 09:01.170 Cars and runways kind of go together. 09:01.490 --> 09:05.750 If you picked a different scene I'd love to see what projects you were going to work on. 09:05.750 --> 09:10.700 Remember to share that in the discussions and I will see you guys in the next lecture.
