00:23 | Welcome to Meet The GIMP. My name is Rolf Steinort and I am recording this in Bremen, Northern Germany. |
00:30 | In this tutorial, I will explain you the drawing tools in detail. |
00:37 | The first drawing tool is Pencil and it works with very hard edges. |
00:44 | Here I have drawn a straight line and if I zoom into the image, you can see each pixel is either black or white. |
01:01 | When I select the paint brush for drawing, I get a line which has soft edges. |
01:08 | And when I switch back to zoom, you can see a hard line with visible jaggies when drawn with pencil. |
01:17 | And when I draw with paint brush I get a soft line. |
01:29 | Back to the pencil here. |
01:32 | You see the pencil is very sharp in the edges and paint brush is smooth. |
01:40 | But you can't see here the jaggies. |
01:44 | This is called trick of the eye. |
01:47 | When I enlarge it, you see it here, it's anti-aliased. |
01:53 | This is the main difference between the pencil and the paint brush. |
01:59 | Otherwise they are nearly equal and their options too. |
02:13 | Now, let's start with the paint brush. |
02:16 | Click on the Paint brush tool in the tool box and you get the options for that. |
02:25 | The Modes are just the same as in the layer modes as you can see here multiply or overlay and so on. |
02:40 | Here is the Opacity slider and by using this you can control the visibility and the colour of the line. |
02:50 | I slide the value to say 25% and now when I draw, I get a light grey line instead of black. |
03:02 | And when I cross this line with a new line you can see that the colour gets stronger but it only happens if I go over it with a new line. |
03:22 | I zoom into this part and select a bigger Brush. |
03:26 | And now when I draw a line, it's gray. |
03:30 | And I draw a second line and the intersection of these two lines is dark gray. |
03:36 | And now, I draw a third line over here and intersection gets more darker gray but when I paint back with the same line it doesn’t get darker. |
03:48 | So, this works only from stroke to stroke and you can easily paint an area with gray and you don’t have to watch carefully while filling this. |
04:15 | Here you can see an option called Incremental . |
04.20 | When you select Incremental, you get much stronger effect. |
04:29 | Let's go to the options of the Brushes and here you can see the spacing of this brush is set to 20%. |
04:45 | Brushes is basically a stamp which stamps the same pattern on and on. |
04:54 | And when I zoom in here, you can see, after 20% of the size of the brush, there is a next impression of this brush. |
05:07 | Here each brush overlays itself. |
05:19 | When you de-select Incremental option, you can see each stamping of the brush but there is no painting over and I have to start a second line. |
05:34 | And when I select Incremental, I can paint over and over. |
05:47 | Go back to 100% . |
05:53 | I have covered Opacity and Incremental options. |
05:57 | Let's go back with the opacity with 100% and I can draw again perfect black. |
06:07 | Incremental is meaningful only if you have an opacity lower than 100%. |
06:15 | Scale slider controls the size of the pen here and when I slide down to 1, you get a small size of the brush. |
06:31 | When I scale the brush to say 0.05, I can draw a very fine line and I set the slider to say 2 and I have a broad line. |
06:48 | Scale basically controls the diameter of the brush and you can also control with the 'square brackets' on the keyboard. |
07:15 | With the help of open square bracket, I can reduce the size of brush and with close square bracket, I can increase the size. |
07:32 | You can see that the brush is nearly invisible. |
07:38 | So, I can adjust the size of brush without leaving the area where I paint. |
07:51 | If someone of the GIMP people are looking forward, I would love to have a button to get back the slider to 1. |
08:03 | So Scale option is covered. |
08:06 | And I will cover the brush in detail in next tutorial. |
08:12 | Here is an option called Pressure sensitivity and I can use it while editing the image. So, |
08:30 | let's have a look, here, at Opacity. |
08:35 | Now, when I draw without a lot of pressure, you get a line which is gray in colour and when I increase the pressure I get a dark colour and when I decrease the perssure I get a light coloured line. |
09:04 | This option is useful if you are painting a mask. |
09:09 | This is quite useful. |
09:17 | Next option is Hardness. |
09:20 | When I draw with not much pressure, there is a soft border and when I increase the pressure, the paint brush acts like a pen. |
09:38 | When I select the pencil tool and draw, I get hard border and this can make a hard border if I really press on the tablet. |
09:51 | I can change the size of the brush with Pressure sensitivity. |
10:00 | I can also change the colour using Pressure sensitivity. |
10:05 | So, I select another colour from the background colour, how this one here? |
10:12 | So, let's select this red colour. |
10:15 | And for the foreground colour, let's select a nice green. |
10:21 | And when I start painting here with the selected colour, with low pressure I get green and when I am increasing the pressure I get red and if released, I get green or greenish stuff again. |
10:41 | And in between the colour changes between green and red. |
10:49 | The last option is using colour from the gradients. |
11:01 | To select the Gradients, go to File, Dialogs and Gradients. |
11:18 | Here is the Gradients. |
11:20 | And now I just grab this window and pull it to here and now I have a gradient here. |
11:28 | In Gradients, I have a big selection of patterns. |
11:33 | Let’s select this one and now I go back here. |
11:42 | Now when I am painting the paint goes through this pattern on the gradient. |
11:48 | Its quite funny for some things like writing or working with gradients. |
12:02 | It looks like made out of tube or so. |
12:07 | These were the options of the gradient. |
12:11 | These options are common for all the tools which uses brushes |
12:30 | i.e, pencil, the paint brush, the eraser and the airbrush which has some additional options. |
12:50 | The Ink has no brush but it has lot of the other options. |
12:55 | The Clone tool, the Healing tool , the Perspective clone tool and even tools like blur, sharpen or dodge and burn has the option of brushes. |
13:14 | Now lets go back to pencil and paint brush. |
13:21 | Just clear this again. |
13:24 | There are some tricks which you can use here. |
13:29 | the 1st trick is about drawing a line. |
13:33 | When I try to draw a straight line its a bit difficult. |
13:39 | But when I 1st set one point with a click and press the shift key, I get a straight line. |
13:48 | Here I have a straight line. |
13:51 | The next trick is, just set one point and press Shift + Ctrl and now the rotation of my line is locked to 15 degree. |
14:05 | And so I can draw easily straight lines with defined angles. |
14:20 | So what a master piece here. |
14:24 | There is something else that you can do with this Shift key. |
14:29 | For that select the gradient tool. |
14:37 | Draw a line with gradient selected and you get lots of different colours. |
14:45 | I select a small brush and de-select the gradient tool and select my standard colours. |
14:55 | Now when I press the Ctrl key, I can select a colour from the line I had drawn and you can see, the foreground colour is changed to the blue tone. |
15:09 | So I can pick a colour, somewhere out of the image which is a quite nice. |
15:17 | And if you want to paint in something in a picture and it has the colour you need. |
15:25 | Just ctrl click on it and you have that specific colour on your palet. |
15:36 | That is a nice trick. |
15:39 | Basically the eraser tool is the same tool as the pen or the brush because its just the opposite of them. |
15:52 | The eraser also paints but it gives the background color. |
15:57 | You can see it here. |
16:00 | But for that you should de-select the Pressure sensitivity and opacity. |
16:08 | When I just switch the foreground colour and the background colour to black and white and switch white as the foreground colour and select the pen, I can get the same effect as the eraser. |
16:25 | After changing the colour erasing gets black. |
16:41 | You can change the foreground and background colour by pressing the X key. |
16:50 | I have covered the pencil, the paint brush and also the eraser in detail. |
