|Welcome to the tutorial of Meet The GIMP. My name is Rolf steinort and I am recording this is Bremen, Northen Germany.  

|The 1st drawing tool is pencil and it works with very hard edges. Here I have drawn a straight line and if I zoom into the image, you can see each pixel is either black or white.  

|When I select the paint brush for drawing, I get a line which has soft edges. And when I switch back to zoom, you can see a hard line with visible jaggis when drawn with pencil. And when I draw with paint brush I get a soft line.  

|Back to the pencil here. You see the pencil is very sharp in the edges and paint brush is smooth. But you can't see here the jaggis. This is called trick of the eye. When I enlarge it you see it here its anti-aliest.  

| This is the main difference between the pencil and the paint brush. Otherwise they are nearly equal and their options too.  

|Now let's start with the paint brush. Click on the paint brush tool in the tool box and you get the options for that.  

|Here is the Opacity slider and by using this you control the visibility and the colour of the line. I slide the value to say 25% and now when I draw, I get a light grey line instead of black. 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.

| I zoom into this part and select a bigger brush. And now when I draw a line its gray. And I draw a 2nd line and the intersection of these 2 lines is dark gray. And now I draw a 3rd line over here and intersection gets more darker gray but when I paint back with the same line it doesn’t get darker.  

|When you select Incremental, you get much stronger effect. Lets go to the options of the brushes and here you can see the spacing of this brush is set to 20%,

|Brushes is basically a stamp which stamps the same pattern on and on. 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. Here each brush overlays itself.  

|When you de-select Incremental option you can see the each stamping of the brush, but there is no painting over and I have to start a second line. And when  I select incremental, I can paint over and over.  

| 05.46

|I have covered opacity and incremental options. Lets go back with the opacity with 100% and I can draw again perfect black.   

|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. Scale basically controls the diameter of the bursh and you can also control with the square brackets on the keyboard.  

|So scale option is covered. And i'll cover the brush in detail in next tutorial.  

|Here is an option called pressure sensitivity and I can use it while editing the image.  

|This option is useful, if you are painting a mask. This is quite useful.  

|Next option is hardness. 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.   

|I can also change the colour using pressure sensitivity. So I select another colour from the background colour, how is this one here. So lets select this red colour.  

|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 release I get green or greenish stuff again. And in between the colour changes between green and red.  

|Here the gradient. And now I just grab this window and pull it to here and now I have a gradient here.  

| Now when I am painting the paint goes through this pattern on the gradient. Its quite funny for some things like writing or work with gradients.   

| These were the options of the gradient. These options are common for all the tools which uses brushes  

|The Ink has no brush but it has lot of the other options. 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. Now lets go back to pencil and paint brush.  

|Just clear this again. There are some tricks which you can use here.  

|the 1st trick is about drawing a line. When I try to draw a straight line its a bit difficult. But when I 1st set one point with a click and press the shift key, I get a straight line. Here I have a straight line. The next trick is, just set one point and press Shift + Ctrl and now the rotation of my line is locked to 15 degree. And so I can draw easily straight lines with defined angles.  

| There is something else that you can do with this Shift key. For that select the gradient tool.  

|Draw a line with gradient selected and you get lots of different colours. I select a small brush and de-select the gradient tool and select my standard colours. 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.  

|So I can pick a colour, somewhere out of the image which is a quite nice. And if you want to paint in something in a picture and it has the colour you need. Just ctrl click on it and you have that specific colour on your palet.  

| That is a nice trick. Basically the eraser tool is the same tool as the pen or the brush because its just the opposite of them.  

| The eraser also paints but it gives background color. You can see it here. But for that you should de-select the brush sensitivity and opacity.  

| When I just switch the foreground 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. After changing the colour erasing gets black.
