|The GIMP people call a selection as a channel. A channel like red, green or blue or an alpha channel which controls the transperancy. Outside of the selection, the value of this channel is zero. And inside its 255 ,and between them is the border, and between them there can be values lower than 255 and higher than zero. So changing a selection or making a selection is changing some numbers.

 +
|-
 +
| 01:48
 +
|So, 'changing a selection' or 'making a selection' is changing some numbers.
  
 
|-
 
|-
−
|02.52
+
| 01:55
−
| The 2nd option is add to the current selection. By selecting that option, I can select different areas in the image and get a quite complicated selection.  
+
| And now, let's have a look at how to make a '''selection'''.  
  
 
|-
 
|-
−
|03.17
+
| 02:01
−
| And if I go to my colour tabs and just pull the colour over to the selection, you can see, all the selected areas are filled with that colour and the area which is selected and not connected is also filled.  
+
|For de-selecting a selection, there are 2 ways.
  
 
|-
 
|-
−
|03.44
+
| 02:05
−
|So adding something to a selection holds every selection as one, even if there’s no connection between the parts of the selection.
+
|First way is, go to '''Select''' and '''None'''.  
  
 
|-
 
|-
−
|03.57
+
| 02:11
−
|Its a bit complicated. Press Ctrl + Z to undo the filling. And shift + Ctrl + A to de-select everything. And back to my options dialog.  
+
| You can also use the key combination of '''Shift + Ctrl+ A''' and get rid of a selection.  
  
 
|-
 
|-
−
| 04.11
+
| 02:22
−
|Now select a square here and select Subtract from the Current Selection. I Select this area but nothing happens. But when I select these area you can see that the edge is cut out. You can see that the frame of selection stays there and when I move it , changes can be made.  
+
| Now, select the '''Rectangle Select''' Tool  and look into the options dialog.  
  
 
|-
 
|-
−
| 04.47
+
| 02:33
−
|So the last selection you made can be change until you click into another palce to get a new selection, you can change your work all the time.  
+
|On the top, there are four choices.
  
 
|-
 
|-
−
| 05.07
+
| 02:36
−
|Now the last option is Intersect with the current selection. Lets try that.  
+
|The first one is '''Replace the current selection'''.  
  
 
|-
 
|-
−
| 05.17
+
| 02:40
−
|I select a rectangle here and the area outside it is not selected and selections which were done before are deleted. And only selection in this rectangle is kept. I can also modify this rectangle until I have the area selected that I wanted.  
+
|So, I select different areas here and you can see that when I select a new area, the old '''selection''' is deleted.
  
 +
|-
 +
|02:52
 +
| The second option is '''Add to the current selection'''.
  
 
|-
 
|-
−
| 05.49
+
|02:58
−
|So now we have covered four modes i.e. Replace, Add, Subtract and Intersect.  
+
| By selecting that option, I can select different areas in the image and get a quite complicated selection.  
  
 
|-
 
|-
−
| 06.06
+
|03:17
−
|You can replace a selection by just clicking. Adding can be done by Click and Shift. So lets try that, I press the shift key and then by clicking I start adding new selections. And when I press the shift key and mouse key, a plus sign appears.  
+
| And if I go to my colour tabs and just pull the colour over to the '''selection''', you can see, all the selected areas are filled with that colour and the area which is selected and not connected is also filled.  
  
 +
|-
 +
|03:44
 +
|So, adding something to a selection holds every selection as one, even if there is no connection between the parts of the selection. 
  
 
|-
 
|-
−
| 06.39
+
|03:57
−
|Now if I want to subtract the selection, I can press the ctrl key and now I press the mouse key and start to move you can see a minus sign. So now I can substract the selection.  
+
|It's a bit complicated.  
  
 
|-
 
|-
−
| 07.02
+
|03:59
−
|And for intersection, Shift, Ctrl should be pressed together and then select an area for intersecting.  
+
|Press '''Ctrl + Z''' to '''undo''' the filling and '''shift + Ctrl + A''' to de-select everything and back to my options dialog.  
  
 
|-
 
|-
−
|07.26
+
| 04:11
−
|If you memorize these key combinations you can select the area faster. And the same key are used by the other selection tool. So you'll just have to learn them only once.
+
|Now, select a square here and select '''Subtract from the current Selection'''.
  
 +
|-
 +
| 04:21
 +
|I Select this area but nothing happens.
 +
 +
|-
 +
| 04:27
 +
|But when I select these areas, you can see that the edge is cut out.
 +
 +
|-
 +
| 04:36
 +
|You can see that the frame of selection stays there and when I move it, changes can be made.
 +
 +
|-
 +
| 04:47
 +
|So, the last selection you made can be changed until you click into another place to get a new selection. You can change your work all the time.
 +
 +
|-
 +
| 05:07
 +
|Now the last option is '''Intersect with the current selection'''.
 +
 +
|-
 +
| 05:14
 +
| Let's try that.
 +
 +
|-
 +
| 05:17
 +
|I select a rectangle here and the area outside it is not selected and selections which were done before are deleted. 
 +
 +
|-
 +
| 05:32
 +
|And only '''selection''' in this rectangle is kept.
 +
 +
|-
 +
| 05:38
 +
|I can also modify this rectangle until I have the area selected that I wanted.
 +
 +
|-
 +
| 05:49
 +
|So now, we have covered four modes i.e. '''Replace, Add, Subtract''' and '''Intersect'''.
 +
 +
|-
 +
| 06:06
 +
|You can replace a selection by just clicking. 
 +
 +
|-
 +
| 06:11
 +
|Adding can be done by '''Click''' and '''Shift'''.
 +
 +
|-
 +
| 06:17
 +
|So, let's try that. I press the '''shift''' key and then by clicking I start adding new '''selections'''.
 +
 +
|-
 +
| 06:29
 +
|And, when I press the '''shift''' key and mouse key, a plus sign appears.
 +
 +
|-
 +
| 06:39
 +
|Now, if I want to subtract the selection, I can press the '''Ctrl''' key and now I press the mouse key and start to move; you can see a minus sign.
 +
 +
|-
 +
| 06:57
 +
| So, now, I can subtract the selection.
 +
 +
|-
 +
| 07:02
 +
|And for intersection, '''Shift, Ctrl''' should be pressed together and then select an area for intersecting.
 +
 +
|-
 +
|07:26
 +
|If you memorize these key combinations you can select the area faster.
 +
 +
|-
 +
|07:33
 +
| And the same keys are used by the other selection tool.
 +
 +
|-
 +
|07:38
 +
|So, you will just have to learn them only once. 
 +
 +
|-
 +
|07:44
 +
|'''Shift, Ctrl, A,''' disable all the selections and bring back to my normal mode and now let's start with other stuff here.
 +
 +
|-
 +
| 07:56
 +
|Next option is '''Feather edges''' and when I select it you get another option here as '''Radius''' count.
 +
 +
|-
 +
| 08:09
 +
| So, I increase it a bit and select an area.
 +
 +
|-
 +
| 08:15
 +
|Now you can see here, there is rounded corner.
 +
 +
|-
 +
| 08:21
 +
| I don’t want rounded corners here.
  
 
|-
 
|-
−

−
|Shift, Ctrl,  A, disable all the selections and brings back to my normal mode and now let's start with other stuff here.  
+
|Just to show you what has happened, I will fill this with black and I zoom into the image.  
  
 
|-
 
|-
−
| 07.56
+
| 08:37
−
|Next option is Feather Edges, and when it you get another option here as Radius Count. So I increase it a bit and select an area. Now you can see here, there is rounded corner. I don’t want rounded corners here. Just to show you what has happened i'll fill this with black and I zoom into the image.  
+
|You can see, here is  black colour in the middle and it fades out near the border and these margin ends are running in-between the real black and the original image and here, the value of selection is 128.  
  
 
|-
 
|-
−
| 08.37
+
| 09:09
−
|You can see here is a black colour in the middle and it fades out near the border and these margin ends are running in between the real black and the original image and here is the value of selection is 128.  
+
|So, the half black colour fades inside the '''selection''' and half outside.  
  
 
|-
 
|-
−
| 09.09
+
| 09:19
−
|So the half black colour fade's inside the selection and half outside. The margin ends is the only real border of your selection when you have a hard selection.

|Feather edges is a nice option to get smooth selections. With  feather selection you can get a less sharp seen and it is easier that way.

| 10:04
 +
|The next option is '''Rounded corners'''.
  
 +
|-
 +
| 10:09
 +
|It’s a rectangle with rounded corner and you can set the radius of the rounded corners.
  
 
|-
 
|-
−
| 10.04

−
|Here is the next option Antialiasing. This option sets the corner painting. I just fill this selection with black and now I go back to my selection tool and i de-select antialiasing and make another selection and fill this also with black.
+
|Here is the next option '''Antialiasing'''.
  
 
|-
 
|-
−
| 11.09
+
|10:34
−
|So select the zoom tool and deselect all selections with Shift + Ctrl + A and zoom into this area. And here the edge is without antialiasing and it is either filled with black or not filled with black. And here you can see the stair of grays.  
+
|This option sets the corner painting.
  
 +
|-
 +
|10:40
 +
|I just fill this '''selection''' with black and now I go back to my selection tool and I de-select '''Antialiasing''' and make another selection and fill this also with black.
  
 
|-
 
|-
−
| 11.42
+
| 11:09
−
|Here you can see the smooth corner without jaggis, and that’s called Antialiasing. This selection does not have a rounded corner but it's series of steps.  
+
|So, select the '''zoom''' tool and de-select all selections with '''Shift + Ctrl + A''' and zoom into this area.
  
 
|-
 
|-
−
| 12.04
+
| 11:24
−
|And when I go back to 100% zoom, I can see here are jaggies and its not smooth but here it is smooth corners and you can easily try it for yourself.
+
|And here, the edge is without '''antialiasing''' and it is either filled with black or not filled with black.
  
 
|-
 
|-
−
|12.32
+
| 11:37
−
| So if you want to have smooth corners then select Antialiasing. And if you want to have these gray tones in here then de-select that option.  
+
|And here, you can see the stair of grays.  
  
 
|-
 
|-
−
|12.55
+
| 11:42
−
|So I select that option and there is a sub option called Expand From Centre I select it and start working with it.  
+
|Here you can see the smooth corner without jaggies and that’s called '''antialiasing'''.
  
 
|-
 
|-
−
|13.13
+
| 11:53
−
|So I place a point here and I start pulling my selection from here.  You can see it grow from that point and this point is always in the middle of the selection. When I deselect that option I can pull selection here and the position of the corner changes according to my selection.  
+
| This selection does not have a rounded corner but it is series of steps.
  
 
|-
 
|-
−
| 13.46
+
| 12:04
−
|There is a key code for this. When I click at this point and press ctrl  I have a selection from centre and the selection expands from centre. And when I release the ctrl key, the selection vanishes.  
+
|And, when I go back to 100% zoom, I can see here are jaggies and it's not smooth but here it is smooth corners and you can easily try it for yourself.
  
 +
|-
 +
|12:32
 +
| So, if you want to have smooth corners then select '''Antialiasing'''.
  
 
|-
 
|-
−
| 14.16
+
|12:42
−
| When I press the Ctrl key before I press the mouse button, I can substract a selection  but when I first press the mouse key and then the Ctrl key I get selection from centre. The next option here is Fixed Aspect Ratio and I can have here pre-selected aspect ratio as 1 by 1 and when I draw it will always be a square.
+
| And if you want to have these gray tones, in here, then deselect that option.  
  
 
|-
 
|-
−
| 15.08
+
|12:55
−
| I can select here 2 by 3 and I always get a selection in 2 by 3 ratio and switching to 3 by 2 gives me a selection in landscape mode.  
+
|So, I select that option and there is a sub option called '''Expand from centre'''.
  
 
|-
 
|-
−
|15.31
+
|13:04
−
|There is another way to create a perfect square. I start the selection at this point and pull and then press shift.Now the fixed aspect ratio is selected with pre-selected value here.  
+
| I select it and start working with it.  
  
 
|-
 
|-
−
| 15.54
+
|13:13
−
| And this is a fast way, so I can select areas with aspect ratios that I want and by just pressing shift.  
+
|So, I place a point here and I start pulling my selection from here.
  
 +
|-
 +
|13:21
 +
| You can see, it grows from that point and this point is always in the middle of the selection.
  
 
|-
 
|-
−
| 16.08
+
|13:31
−
|The next option is highlight and when I use that, the area that is not selected is gray and all the area that is selected is white. And this concerns only the current selection so lets de-select it and look at other options. Here you can set these values by hand and if you click on fix here, then I can't change the size of the selection.But if I want to have set width two pixels less and height one pixel more so it fine tunes the selection.  
+
|When I de-select that option, I can pull '''selection''' here and the position of the corner changes according to my selection.  
  
 +
|-
 +
| 13:46
 +
|There is a key code for this.
  
 
|-
 
|-
−
| 16.59
+
| 13:51
−
| I can move the selection a little bit to the right by increasing the value of X which is the point of origin. An when I click on fix, I can move the whole selection. So the ‘X’ and ‘Y’ value is the point of origin of the left top point and with fix button I can block the movement.  
+
| When I click at this point and press '''Ctrl''', I have a '''selection''' from center and the selection expands from center.  
  
 
|-
 
|-
−
| 17.30
+
| 14:06
−
| The next option is the guides. I can select a Centre Line which shows me where the middle point of the selection is. I can have the Rule Of Thirds, which is used for the graphic work or I can have the Golden Selections which is similar to the Rule Of Thirds.  
+
|And when I release the '''Ctrl''' key, the selection vanishes.  
  
 
|-
 
|-
−
| 18.00
+
| 14:16
−
| On the bottom is Auto Shrink Selection and Shrink Merged. Auto Shrink Selection is not very useful. But Shrink Merged is an option which if selected, the algorithm looks at the all the layers, and if de-selected only the layer that you are working on is taken into consideration.  
+
| When I press the '''Ctrl''' key before I press the mouse button, I can subtract a selection  but when I first press the mouse key and then the '''Ctrl''' key I get selection from centre.  
  
 
|-
 
|-
−
| 18.34
+
| 14:42
−
|Before having a recap of these options we'll talk about Ellipse Selection. So de-select all the selections by pressing Shift+ctrl+A. On the top you get the same options like Replace current selection, Add to the selection with Shift key before clicking and Subtract with Ctrl key before clicking and Intersect with Shift and Ctrl key before clicking.  
+
| The next option here is '''Fixed aspect ratio''' and I can have here preselected aspect ratio as 1 by 1 and when I draw, it will always be a square.
  
 
|-
 
|-
−
| 19.12
+
| 15:08
−
| Antialiasing is again for smooth edges. It is more important with ellipse then with rectangles because ellipse are always round.  
+
| I can select here 2 by 3 (2:3) and I always get a selection in 2 by 3 ratio and switching to 3 by 2 (3:2) gives me a selection in landscape mode.  
  
 
|-
 
|-
−
| 19.26
+
|15:31
−
|Feather edges the same option as in rectangle. When I fill it with black , you can see a smooth gradient between black and white and these margin ends are in between black and white.  
+
|There is another way to create a perfect square.
  
 
|-
 
|-
−
| 19.54
+
|15:36
−
|Expand from centre also works the same with the Ctrl key after clicking the mouse button.  
+
| I start the selection at this point and pull and then press '''shift'''.
  
 
|-
 
|-
−
| 20.05
+
|15:46
−
|Fixed aspect ratio is also the same, after clicking the mouse button you get a perfect circle with aspect ratio 1 by 1. Now lets come to the last tool I want to show you for today and thats the Free Select tool.  
+
| Now the '''Fixed aspect ratio''' is selected with preselected value here.  
  
 
|-
 
|-
−
| 20.29
+
| 15:54
−
| When I select that tool I see the same options here and also the keys work the same for Add, Replace, Subtract and Intersect. It has only 2 further option i.e Antialiasing and feather edges with same functions. Here I get the radius of the circle and i de-select it now.  
+
| And this is a fast way, so I can select areas with aspect ratios that I want and by just pressing '''shift'''.  
  
 
|-
 
|-
−
| 21.00
+
| 16:08
−
| I select this lower part of the leaf to show you as example. And I click into the image where I want to start the selection and draw a line and follow the border of the leaf.
+
|The next option is '''Highlight''' and when I use that, the area that is not selected is gray and all the area that is selected is white.  
  
 
|-
 
|-
−
| 21.33
+
| 16:24
−
|So now I have selected this area. I zoom into the image to do fine tuning. And in my selection dialog I select Add To The Current Selection and start adjusting the selection.  
+
|And this concerns only the current selection so let's de-select it and look at other options.
  
 
|-
 
|-
−
| 22.10
+
| 16:35
−
|The algorithm looks for the shortest way to the point where you started the selection. For making the selection easy I can use a Quick Mask.  
+
| Here you can set these values by hand and if you click on '''Fix''' here, then I can't change the size of the selection.
  
 
|-
 
|-
−
| 22.26
+
| 16:47
−
|On the bottom left corner is the option, Toggle Quick Mask and I toggle that and you can see now my whole image is red.  
+
|But if I want to have set width two pixels less and height one pixel more, so it fine tunes the selection.
  
 
|-
 
|-
−
| 22.38
+
| 16:59
−
| It is a bit confusing option because the area which I have selected and the area which is not selected is shown in red. So I go to the toggle and right clicking on it gives me Configure, Colour and Opacity and here I can set a color so i set it to blue.  
+
| I can move the selection a little bit to the right by increasing the value of X which is the point of origin.

 +
|-
 +
| 17:44
 +
| I can have the '''Rule of thirds''' which is used for the graphic work or I can have the '''Golden sections''' which is similar to the '''Rule of thirds'''.

| 18:00
 +
| On the bottom is '''Auto Shrink Selection''' and '''Shrink merged'''.
 +
 
 +
|-
 +
| 18:08
 +
| '''Auto Shrink Selection''' is not very useful. 
 +
 
 +
|-
 +
| 18:14
 +
| But '''Shrink merged''' is an option which if selected, the algorithm looks at all the '''layers''' and if de-selected only the '''layer''' that you are working on, is taken into consideration.
 +
 
 +
|-
 +
| 18:34
 +
|Before having a recap of these options, we will talk about '''Ellipse''' selection.
 +
 
 +
|-
 +
| 18:42
 +
|So, de-select all the selections by pressing '''Shift + ctrl + A'''.
 +
 
 +
|-
 +
| 18:49
 +
|On the top, you get the same options like '''Replace current selection, Add to the selection''' with '''Shift''' key before clicking and '''Subtract''' with '''Ctrl''' key before clicking and '''Intersect''' with '''Shift''' and '''Ctrl''' key before clicking.
 +
 
 +
|-
 +
| 19:12
 +
| '''Antialiasing''' is again for smooth edges.
 +
 
 +
|-
 +
| 19:17
 +
| It is more important with ellipse than with rectangles because ellipses are always round.
 +
 
 +
|-
 +
| 19:26
 +
|'''Feather edges''', the same option as in rectangle.
 +
 
 +
|-
 +
| 19:32
 +
| When I fill it with black , you can see a smooth gradient between black and white and these margin ends are in-between black and white.
 +
 
 +
|-
 +
| 19:54
 +
|'''Expand from center''' also works the same with the '''Ctrl''' key, after clicking the mouse button.
 +
 
 +
|-
 +
| 20:05
 +
|'''Fixed aspect ratio''' is also the same. After clicking the mouse button, you get a perfect circle with aspect ratio 1 by 1 (1:1).
 +
 
 +
|-
 +
| 20:19
 +
|Now, let's come to the last tool I want to show you for today and that's the '''Free Select''' tool. 
 +
 
 +
|-
 +
| 20:29
 +
| When I select that tool, I see the same options here and also the keys work the same for '''Add, Replace, Subtract''' and '''Intersect'''.
 +
 
 +
|-
 +
| 20:44
 +
|  It has only two further options i.e '''Antialiasing''' and '''Feather edges''' with same functions.
 +
 
 +
|-
 +
| 20:54
 +
| Here, I get the '''Radius''' of the circle and I de-select it now.
 +
 
 +
|-
 +
| 21:00
 +
| I select this lower part of the leaf to show you as example. 
 +
 
 +
|-
 +
| 21:08
 +
|And I click into the image where I want to start the '''selection''' and draw a line and follow the border of the leaf.
 +
 
 +
|-
 +
| 21:33
 +
|So, now I have selected this area.
 +
 
 +
|-
 +
| 21:38
 +
|I zoom into the image to do fine tuning.
 +
 
 +
|-
 +
| 21:43
 +
| And in my selection dialog, I select '''Add to the current selection''' and start adjusting the selection.
 +
 
 +
|-
 +
| 22:10
 +
|The algorithm looks for the shortest way to the point where you started the selection.
 +
 
 +
|-
 +
| 22:19
 +
|For making the selection easy, I can use a '''Quick Mask'''.
 +
 
 +
|-
 +
| 22:26
 +
|On the bottom left corner is the option, '''Toggle Quick Mask''' and I toggle that and you can see now my whole image is red.
 +
 
 +
|-
 +
| 22:38
 +
| It is a bit confusing option because the area which I have selected and the area which is not selected are shown in red.
 +
 
 +
|-
 +
| 22:51
 +
| So, I go to the toggle and right clicking on it gives me '''Configure Colour and Opacity''' and here I can set a color, so I set it to blue.
 +
 
 +
|-
 +
| 23:07
 +
| Now the area which is selected is Red and all the area is blue.
 +
 
 +
|-
 +
| 23:19
 +
| And now, I select a '''pen''' and start painting the selected area but before that I change the '''foreground''' and '''background colour'''  with the key ’X’.
 +
 
 +
|-
 +
| 23:38
 +
| And now I start to paint.
 +
 
 +
|-
 +
| 23:48
 +
| And when I over-paint the border, I can paint with the '''background colour'''. 
 +
 
 +
|-
 +
| 24:00
 +
| For painting, I should select the right size of the brush.  
 +
 
 +
|-
 +
| 24:23
 +
|And when I untoggle the mask, you can see, here is the mistake in '''selection''' and here also.
 +
 
 +
|-
 +
| 24:35
 +
|So, I select the toggle and correct the mistakes.
 +

|Fixed.

Time Narration
00:23 Welcome to the tutorial of Meet The GIMP.
00:25 My name is Rolf Steinort and I am recording this in Bremen, Northern Germany.
00:31 Let's start today's tutorial with this image.
00:34 Today I will work with this image only to use it as an example.
00:44 Before we start to work with selection, I think you should understand a bit about what selections really are.
00:57 This square is a selection and this part is outside of the selection.
01:06 These moving lines, here, are the border of the selection.
01:15 The GIMP people call a selection as a channel;
01:19 a channel like Red, Green or Blue or an Alpha channel which controls the transparency.
01:28 Outside of the selection, the value of this channel is zero
01:33 and inside it's 255 and between them is the border and between them there can be values lower than 255 and higher than zero.
01:48 So, 'changing a selection' or 'making a selection' is changing some numbers.
01:55 And now, let's have a look at how to make a selection.
02:01 For de-selecting a selection, there are 2 ways.
02:05 First way is, go to Select and None.
02:11 You can also use the key combination of Shift + Ctrl+ A and get rid of a selection.
02:22 Now, select the Rectangle Select Tool and look into the options dialog.
02:33 On the top, there are four choices.
02:36 The first one is Replace the current selection.
02:40 So, I select different areas here and you can see that when I select a new area, the old selection is deleted.
02:52 The second option is Add to the current selection.
02:58 By selecting that option, I can select different areas in the image and get a quite complicated selection.
03:17 And if I go to my colour tabs and just pull the colour over to the selection, you can see, all the selected areas are filled with that colour and the area which is selected and not connected is also filled.
03:44 So, adding something to a selection holds every selection as one, even if there is no connection between the parts of the selection.
03:57 It's a bit complicated.
03:59 Press Ctrl + Z to undo the filling and shift + Ctrl + A to de-select everything and back to my options dialog.
04:11 Now, select a square here and select Subtract from the current Selection.
04:21 I Select this area but nothing happens.
04:27 But when I select these areas, you can see that the edge is cut out.
04:36 You can see that the frame of selection stays there and when I move it, changes can be made.
04:47 So, the last selection you made can be changed until you click into another place to get a new selection. You can change your work all the time.
05:07 Now the last option is Intersect with the current selection.
05:14 Let's try that.
05:17 I select a rectangle here and the area outside it is not selected and selections which were done before are deleted.
05:32 And only selection in this rectangle is kept.
05:38 I can also modify this rectangle until I have the area selected that I wanted.
05:49 So now, we have covered four modes i.e. Replace, Add, Subtract and Intersect.
06:06 You can replace a selection by just clicking.
06:11 Adding can be done by Click and Shift.
06:17 So, let's try that. I press the shift key and then by clicking I start adding new selections.
06:29 And, when I press the shift key and mouse key, a plus sign appears.
06:39 Now, if I want to subtract the selection, I can press the Ctrl key and now I press the mouse key and start to move; you can see a minus sign.
06:57 So, now, I can subtract the selection.
07:02 And for intersection, Shift, Ctrl should be pressed together and then select an area for intersecting.
07:26 If you memorize these key combinations you can select the area faster.
07:33 And the same keys are used by the other selection tool.
07:38 So, you will just have to learn them only once.
07:44 Shift, Ctrl, A, disable all the selections and bring back to my normal mode and now let's start with other stuff here.
07:56 Next option is Feather edges and when I select it you get another option here as Radius count.
08:09 So, I increase it a bit and select an area.
08:15 Now you can see here, there is rounded corner.
08:21 I don’t want rounded corners here.
08:25 Just to show you what has happened, I will fill this with black and I zoom into the image.
08:37 You can see, here is black colour in the middle and it fades out near the border and these margin ends are running in-between the real black and the original image and here, the value of selection is 128.
09:09 So, the half black colour fades inside the selection and half outside.
09:19 The margin end is the only real border of your selection when you have a hard selection.
09:29 Feather edges is a nice option to get smooth selections.
09:35 With Feather selection, you can get a less sharp scene and it is easier that way.
09:45 Technically minded people call Feather selection as Gaussian Blur and the Radius I selected here is the radius of the Gaussian Blur.
10:04 The next option is Rounded corners.
10:09 It’s a rectangle with rounded corner and you can set the radius of the rounded corners.
10:20 Here is the round part and these margins are the straight parts.
10:28 Here is the next option Antialiasing.
10:34 This option sets the corner painting.
10:40 I just fill this selection with black and now I go back to my selection tool and I de-select Antialiasing and make another selection and fill this also with black.
11:09 So, select the zoom tool and de-select all selections with Shift + Ctrl + A and zoom into this area.
11:24 And here, the edge is without antialiasing and it is either filled with black or not filled with black.
11:37 And here, you can see the stair of grays.
11:42 Here you can see the smooth corner without jaggies and that’s called antialiasing.
11:53 This selection does not have a rounded corner but it is series of steps.
12:04 And, when I go back to 100% zoom, I can see here are jaggies and it's not smooth but here it is smooth corners and you can easily try it for yourself.
12:32 So, if you want to have smooth corners then select Antialiasing.
12:42 And if you want to have these gray tones, in here, then deselect that option.
12:55 So, I select that option and there is a sub option called Expand from centre.
13:04 I select it and start working with it.
13:13 So, I place a point here and I start pulling my selection from here.
13:21 You can see, it grows from that point and this point is always in the middle of the selection.
13:31 When I de-select that option, I can pull selection here and the position of the corner changes according to my selection.
13:46 There is a key code for this.
13:51 When I click at this point and press Ctrl, I have a selection from center and the selection expands from center.
14:06 And when I release the Ctrl key, the selection vanishes.
14:16 When I press the Ctrl key before I press the mouse button, I can subtract a selection but when I first press the mouse key and then the Ctrl key I get selection from centre.
14:42 The next option here is Fixed aspect ratio and I can have here preselected aspect ratio as 1 by 1 and when I draw, it will always be a square.
15:08 I can select here 2 by 3 (2:3) and I always get a selection in 2 by 3 ratio and switching to 3 by 2 (3:2) gives me a selection in landscape mode.
15:31 There is another way to create a perfect square.
15:36 I start the selection at this point and pull and then press shift.
15:46 Now the Fixed aspect ratio is selected with preselected value here.
15:54 And this is a fast way, so I can select areas with aspect ratios that I want and by just pressing shift.
16:08 The next option is Highlight and when I use that, the area that is not selected is gray and all the area that is selected is white.
16:24 And this concerns only the current selection so let's de-select it and look at other options.
16:35 Here you can set these values by hand and if you click on Fix here, then I can't change the size of the selection.
16:47 But if I want to have set width two pixels less and height one pixel more, so it fine tunes the selection.
16:59 I can move the selection a little bit to the right by increasing the value of X which is the point of origin.
17:10 And when I click on Fix, I can move the whole selection.
17:17 So, the ‘X’ and ‘Y’ values are the point of origin of the left top point and with Fix button, I can block the movement.
17:30 The next option is the Guides.
17:34 I can select a Centre line which shows me where the middle point of the selection is.
17:44 I can have the Rule of thirds which is used for the graphic work or I can have the Golden sections which is similar to the Rule of thirds.
18:00 On the bottom is Auto Shrink Selection and Shrink merged.
18:08 Auto Shrink Selection is not very useful.
18:14 But Shrink merged is an option which if selected, the algorithm looks at all the layers and if de-selected only the layer that you are working on, is taken into consideration.
18:34 Before having a recap of these options, we will talk about Ellipse selection.
18:42 So, de-select all the selections by pressing Shift + ctrl + A.
18:49 On the top, you get the same options like Replace current selection, Add to the selection with Shift key before clicking and Subtract with Ctrl key before clicking and Intersect with Shift and Ctrl key before clicking.
19:12 Antialiasing is again for smooth edges.
19:17 It is more important with ellipse than with rectangles because ellipses are always round.
19:26 Feather edges, the same option as in rectangle.
19:32 When I fill it with black , you can see a smooth gradient between black and white and these margin ends are in-between black and white.
19:54 Expand from center also works the same with the Ctrl key, after clicking the mouse button.
20:05 Fixed aspect ratio is also the same. After clicking the mouse button, you get a perfect circle with aspect ratio 1 by 1 (1:1).
20:19 Now, let's come to the last tool I want to show you for today and that's the Free Select tool.
20:29 When I select that tool, I see the same options here and also the keys work the same for Add, Replace, Subtract and Intersect.
20:44 It has only two further options i.e Antialiasing and Feather edges with same functions.
20:54 Here, I get the Radius of the circle and I de-select it now.
21:00 I select this lower part of the leaf to show you as example.
21:08 And I click into the image where I want to start the selection and draw a line and follow the border of the leaf.
21:33 So, now I have selected this area.
21:38 I zoom into the image to do fine tuning.
21:43 And in my selection dialog, I select Add to the current selection and start adjusting the selection.
22:10 The algorithm looks for the shortest way to the point where you started the selection.
22:19 For making the selection easy, I can use a Quick Mask.
22:26 On the bottom left corner is the option, Toggle Quick Mask and I toggle that and you can see now my whole image is red.
22:38 It is a bit confusing option because the area which I have selected and the area which is not selected are shown in red.
22:51 So, I go to the toggle and right clicking on it gives me Configure Colour and Opacity and here I can set a color, so I set it to blue.
23:07 Now the area which is selected is Red and all the area is blue.
23:19 And now, I select a pen and start painting the selected area but before that I change the foreground and background colour with the key ’X’.
23:38 And now I start to paint.
23:48 And when I over-paint the border, I can paint with the background colour.
24:00 For painting, I should select the right size of the brush.
24:23 And when I untoggle the mask, you can see, here is the mistake in selection and here also.
24:35 So, I select the toggle and correct the mistakes.
24:44 Fixed.
24:50 So, the Quick Mask is an easy way to get a complicated selection right.
24:59 You can use the Quick Mask selection as a tool.
25:05 You can change the opacity of the mask and now you can hardly see the parts which are not selected.
25:19 50% opacity is the right amount in most of the cases.
25:28 You can choose a colour of your choice for the unselected areas.
25:36 There is another option here called Mask Selected Areas.
25:43 It has just the opposite effect of the Quick Mask.
25:48 So now, the selected area is painted blue and this looks better in this case here.
25:59 And when you de-select the Quick Mask, you can see your selection.
26:08 So now, let's pretend that I have made a perfect selection here and I want to save the selection for the next time to work and don't want to loose it.
26:29 Just go to Select and Save to Channel because selections are basically channels.
26:45 I save it as Mask1 and it will be stored with the ’XCF’ file.
26:55 So now, I can de-select everything with Shift + Ctrl + A.
27:02 Select another part and when I go back to my selection here, I can add to the selection or subtract from selection or even intersect with selection and my selection is back here.
27:23 So, if you want to save that, just go to Select and Save to Channel. Good Bye.
