Time Narration
00:23 Welcome to Meet The GIMP.
00:25 My name is Rolf Steinort and I am recording this in Bremen, Northern Germany.
00:31 Today, we will talk about the Fuzzy Select Tool.
00:36 It is closely related to the Select by Colour tool.
00:40 But the Fuzzy Select Tool selects only one contiguous region and the colour select tool selects all regions with similar colours.
00:54 There are some similar options like Replace, Add, Subtract and Intersect with the current selection and now I select Replace.
01:08 Here you can see the same option, Antialiasing.
01:13 If we select Antialiasing, border of the selection is not sharp and you get smooth corners.
01:23 And if it is not selected then you have a really sharp border between selected and unselected.
01:33 The further options are Feather edges and Select transparent areas.
01:41 Select transparent areas is useful while using mask sensor on perhaps.
01:50 Sample merged is the same as with the other and it selects all the visible layers.
01:58 If it is not selected then it works on current layer.
02:04 If you want to select something from the total output of image then select this option.
02:11 Here is Threshold which defines how much difference between the colours is allowed to be in the selection or when something is out of selection.
02:24 It helps in selecting the pixels that have one definite colour.
02:30 The next important selection is, which mode do you want to have in the selection.
02:37 The Composite mode is the gray value of added Red, Green and Blue channels.
02:44 You can select the Red, the Green, the Blue channel or the Hue, Saturation or the Value channel as the base for your selection.
02:56 Now let's try Fuzzy Select Tool.
03:01 I just click into the image and the Threshold is zero, so let's see what happens.
03:08 I make a selection which is one pixel in size.
03:13 Now I increase the amount of Threshold to say 30 and click into the image and click on Toggle Quick Mask here.
03:28 Now you can see the area which is selected.
03:37 I de-select the Quick Mask toggle, press tab to get the toolbox and press Shift+Ctrl+A to unselect everything.
03:49 I can do this in a different way and for that, I decrease the Threshold to zero and click into the image and now, I am drawing the mouse down and right.
04:03 When I increase the threshold, you can see that I am going into this blue area but I am still on the wall.
04:13 I think, this tool is more useful for graphic designers and not for photographers.
04:22 You can change the Threshold by just pulling the mouse.
04:26 This works the same in colour selection tool.
04:32 I change Select by from Composite to Hue and click at the same point and draw to the bottom.
04:43 You can see that I have a way better selection of blue, green part of the wall, than I had before.
04:54 So, choosing the right method of colour definition gives good result with this tool.
05:05 I click into the quick mask and here you see it’s nearly perfect; only some parts to repair and I would do that with painting in the quick mask and not with these selection tools.
05:25 If you are confused about selecting the mode then you can see your image in different channels in the Channels mode.
05:41 Select the Blue channel and you see that everything has nearly the same blue value.
05:50 In the Green channel, there are some differences.
05:55 In the Red channel, it’s nearly the same here.
05:59 So, I would select the Green channel for selecting or in this case Hue channel.
06:10 Selecting colour is the next tool here and it has the same function and same options here.
06:19 It has only one difference.
06:22 If you click here, you will select all fields with this colour and not one contiguous area.
06:32 The colour selection tool selects all the areas with the similar colour.
06:41 The name of the next tool is Intelligent scissors or Scissors selection tool .
06:48 This algorithm looks for edges and tries to follow them with the selection.
06:56 And I want to select here, these letter boxes.
07:10 So, I activate the selection tool and I pull a point here and I get a plus sign near the cursor and I simply select the points.
07:42 The algorithm is supposed to follow the borders and you can see here, it didn’t take the other way, it took the inside way.
07:56 I zoom into the image and now I can draw this point up to here and there was a mistake with selecting this point.
08:13 So, I pull these points up and you can see the algorithm follows the border, if you give enough information where to follow.
08:30 It looks pretty good but I usually don’t use this because there are better ways to do this.
08:44 I think, I would use the colour selection tool because it always takes the wrong way round.
08:56 So, I finished with the selection.
09:10 I just click on the first point here and the cursor changes to plus.
09:17 Now, put the next point and I have these two rings making a loop out of it.
09:25 I can still move the point around here and make the selection better.
09:33 So, when I now click into the selection second time, the selection is selected.
09:42 And, to look at the quality, I activate the Quick Mask and zoom into it.
09:57 Now, I look around in the selection.
10:04 Here is my fault, I should have clicked here.
10:10 So, this is the fairly intelligent scissors.
10:17 The next and the last tool I want to cover today is the Foreground Selection Tool.
10:24 It was quite sensation when the algorithm came out sometime ago and it was not so sensational in using in the GIMP.
10:37 But, let's give it a try.
10:41 Here are the same modes and antialiasing isn’t activatable.
10:48 And here, I want to select one single area and I want to select the statue.
10:57 So, first I zoom into the image to get a better control.
11:06 Now, I select the selection tool and I can select contiguous region or different region but I select the Contiguous region.
11:21 First I make a rough selection here, with the automatic laser tool. And now you can see that the area which is not selected, is in blue colour.
11:44 I have selected a brush here and I can control the diameter of the brush with this slider and I paint through this stuff I want to have selected.
11:59 I have to see that I don’t select stuff which I don’t want to have in the image.
12:17 When I release the mouse button, the algorithm starts to work and some areas here have to be selected.
12:27 Every time the selection gets updated and area that is similar to the stuff I just painted over, gets selected.
12:42 Now, I click on Mark Background and start painting the background that I don’t want to have in the image.
12:54 This tool works better when there is more difference between the selected part and the stuff which is not selected and here the difference is not big enough.
13:12 Just press Enter to accept the selection.
13:17 I think, you have got an idea of how this tool works.
13:27 The Paths tool belongs also to this part but I will cover that sometimes else.
13:36 In the Select menu, there are some other stuff you can do with selections and I will cover that also sometime else.
13:48 So, this was it for this tutorial.
13:52 Let me hear some comments and I promise you for the next show with really new things which are viewer generated content.
14:05 You will find a link to this file in the show notes at meetthegimp.org and if you want to leave a comment then please do that.
14:19 This is Hemant Waidande, dubbing for the Spoken Tutorial Project.
