WEBVTT 00:00:05.000 --> 00:00:10.000 And so we're going to look at drawing demo 00:00:10.000 --> 00:00:20.000 going to look the cube and cylinder 00:00:20.000 --> 00:00:30.000 and I'm going to show you how you can render these described as three-dimensional objects using a marker and pastels 00:00:30.000 --> 00:00:40.000 in the first instance with a look at the cube and cylinder as matte finish 00:00:40.000 --> 00:00:50.000 so get a blue marker 00:00:50.000 --> 00:01:00.000 I'm going to apply marker to this cube and very important to do something I would recommend I've done it for 00:01:00.000 --> 00:01:08.571 It is very easy to transfer ink pencil or pastel from paper onto the side of your hand and vice versa 00:01:08.571 --> 00:01:17.142 likely end up transferring muck so I got into a long time ago trying to keep paper under my hand 00:01:17.142 --> 00:01:25.714 Particularly important when doing pastel but let's not worry for the moment 00:01:25.714 --> 00:01:34.285 I apply my blue marker to this top surface of the cube 00:01:34.285 --> 00:01:42.857 Remember the trick is to try and move it fairly quickly if you're trying to keep this wet ink front 00:01:42.857 --> 00:01:51.428 So coming back trying to keep in the edges as best as I can 00:01:51.428 --> 00:01:59.999 Got that first face in 00:02:00.000 --> 00:02:08.571 now coming in the vertical face 00:02:08.571 --> 00:02:17.142 I would recommend that you try to move the marker in sympathy with surface 00:02:17.142 --> 00:02:25.714 so vertical flat surface here so I'm moving in vertical strokes so that means is that if I don't manage to achieve a flat finish and sometimes when people are early on with markers they struggle 00:02:25.714 --> 00:02:34.285 it's not the end of the world if you don't get it 00:02:34.285 --> 00:02:42.857 At least if there are streaks that are kind of in sympathy with the form 00:02:42.857 --> 00:02:51.428 To note that this marker is probably on it's way out 00:02:51.428 --> 00:03:00.000 it struggles to put it down ink down as quickly as I'd like 00:03:00.000 --> 00:03:07.500 hopefully going to let me finish this successfully 00:03:07.500 --> 00:03:15.000 Putting this face in 00:03:15.000 --> 00:03:22.500 This marker is not long for this world 00:03:22.500 --> 00:03:30.000 Only just 00:03:30.000 --> 00:03:37.500 So I put my three faces 00:03:37.500 --> 00:03:45.000 At the moment there is not a really great sense of 3-D are all of these faces at the same tonal intensity 00:03:45.000 --> 00:03:52.500 so it looks very flat and what we need to do now is to address that and bring out the dimensionality 00:03:52.500 --> 00:04:00.000 the key thing whenever you are sketching or drawing something is you need to be clear about your light source 00:04:00.000 --> 00:04:06.666 I always look on the basis that my light comes from my right side coming in about 45째 angle over my shoulder 00:04:06.666 --> 00:04:13.333 think of it as a kind of like if you were standing in a desert 00:04:13.333 --> 00:04:20.000 light you might getting towards evening 00:04:20.000 --> 00:04:26.666 so not really high-level light coming at a lower angle 00:04:26.666 --> 00:04:33.333 Sun is coming from the right-hand side is what you would now find that the upper surface which is horizontal flat 00:04:33.333 --> 00:04:40.000 facing up towards the sky 00:04:40.000 --> 00:04:46.666 catch the most light quite highly illuminated 00:04:46.666 --> 00:04:53.333 the two vertical surfaces not as much light 00:04:53.333 --> 00:05:00.000 basically facing sideways so need to be tonally darker than this flat surface 00:05:00.000 --> 00:05:06.000 Because my light is coming from the right 00:05:06.000 --> 00:05:12.000 means this right-hand vertical face is still facing towards the light source 00:05:12.000 --> 00:05:18.000 so although darker than the upper surface still have a reasonable amount of illumination on it 00:05:18.000 --> 00:05:24.000 surface the darkest is this surface 00:05:24.000 --> 00:05:30.000 the surface which is facing to the left and is effectively that is almost in the shade 00:05:30.000 --> 00:05:36.000 thing you can do with marker is use the same colour marker okay you can use it up to 3 times possibly 4 00:05:36.000 --> 00:05:42.000 depends on I think for safety normally no more than 3 00:05:42.000 --> 00:05:48.000 So I can do now I hope the marker is not going to give out meanwhile 00:05:48.000 --> 00:05:54.000 I can come in and apply second layer of marker to those two vertical faces 00:05:54.000 --> 00:06:00.000 again moving quite quickly 00:06:00.000 --> 00:06:10.000 ERROR - transcript text not found!
