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 The GIMP is a very powerful image manipulation program.
00:35 In this first tutorial, I want to give you a small tour of GIMP and its features.
00:39 I will briefly demonstrate you how to prepare an image for the web.
00:43 I will give detailed explanation in future tutorials.
00:48 To open an image, I will just drag and drop the image on to the tool box.
00:53 And here it is!
00:55 Let’s have a look at this image.
00:57 I want to make this image ready for the web.
01:02 Let's see what I can do with it.
01:04 First, the image is tilted; so I have to rotate it a bit.
01:09 Then I want to crop it to remove this part - the back of a person.
01:16 The 3rd thing I want to do is to bring in more colors and contrast.
01:22 I also want to re-size the image because now its nearly 4000 pixels wide which is far too much.
01:31 And then I want to sharpen it and save it as a JPEG image.
01:38 Let’s start with rotating.
01:40 I zoom into the part of the image where it is most obvious that the image is tilted. You can see it here.
01:49 By the way, you can move around in the image by pressing Space and just moving the cursor.
01:56 And now I choose the Rotate tool by clicking here.
02:00 In the Rotate tool, there are some options set by default, to values suited for graphical work and not for photographic work.
02:09 So, here Direction is set to Normal (Forward) but I will set it to Corrective (Backward).
02:14 I check if I have the best Interpolation. So, that's fine.
02:17 And in the Preview, I choose Grid instead of the Image.
02:22 I shall increase the no. of grid lines by moving the slider. You will see it soon.
02:30 Now I will click on the image and get a grid, overlaid on the image.
02:36 This grid is straight.
02:38 And I can rotate it and GIMP will rotate the image in the same direction in the Corrective mode so that the grid is straight again.
02:51 Let me demonstrate. I will rotate the grid like this.
02:56 I will check the other part of the image to make sure.
03:00 Looks good to me.
03:02 Now, I will click on the Rotate button.
03:06 This will take some time since the image is about 10 mega-pixels.
03:13 And it is done!
03:14 The image has rotated.
03:16 Let's have a look at the whole picture. Shift + Ctrl + E brings us back to the image.
03:22 Next step is Cropping.
03:25 I chose the Crop tool by clicking here.
03:28 I want to keep the aspect ratio of the image as 3:2.
03:33 For that, I check Fixed Aspect ratio here and type in 3:2.
03:39 Just clicking to come out of that box.
03:43 And now, I can start cropping.
03:45 I want to include the feet of this person here but exclude this part of the image.
03:52 So, I start here at this point and pressing the left mouse button, I drag upward towards the left to select the area.
04:01 Note that the aspect ratio is constant.
04:06 And now I have to decide how far to drag.
04:12 I think this is quite good.
04:18 Let’s check the borders.
04:21 We have excluded this part. There is a person sitting here.
04:28 I think there is enough room here for the person to be in the picture.
04:35 So, I will leave it that way since it looks nice.
04:41 There are windows here, on the top.
04:44 And there are enough of them in the image, to see them as windows.
04:50 But I think there is not enough room around here, at the feet.
04:54 So, I'll just click on the image, and drag it a bit down.
04:58 I think this is good now.
05:01 But now there are not enough windows seen here and the person seated here is very near to the border.
05:08 So, lets make the image a bit larger.
05:11 We are running into a problem hereC. Perhaps you can see it.
05:18 This happened during the rotation.
05:21 There is a small part here which is transparent now.
05:25 I don’t want to include that.
05:33 So, lets go back to Crop tool.
05:35 I want a bit more room here; so I am dragging this up.
05:38 Not so far.
05:40 I think this is quite good.
05:44 Now just click on the image and here we have the cropped & rotated image.
05:50 Shift + Ctrl + E brings us back to the full view.
05:56 Next step is to boost the colors & contrast a bit.
06:02 There are several ways here. I could use the color levels - here it is, the curves or some sliders.
06:11 But I will try doing this with Layers.
06:18 I simply make a copy of this layer here.
06:23 And change the Layers mode to Overlay.
06:30 And you can see, its a very strong effect. I don’t want to have it that much.
06:36 So, I slide the Opacity slider down to a value where I think its looking good.
06:42 Little more perhaps.
06:46 Ok, I think this is good enough.
06:50 I can always change that unless I right-click the mouse here to go to the channel list and say 'Flatten image' or 'Merge visible layers'.
07:01 Then all the changes become permanent
07:03 except if I go into History here and go back and undo the history.
07:10 But we’ll cover that later.
07:13 Next step is Resizing.
07:16 I will click on the Image menu & select Scale Image option.
07:27 Here, I will just type in 800 pixels
07:32 and I get the value for the Height automatically.
07:36 When I unlock this link here, I could distort the image while re-sizing it.
07:44 Interpolation
07:45 I think I will choose Cubic. I found that the highest layer here gives some art effects with brick buildings. Its strange and I will have to check that out.
08:02 Now, click on Scale.
08:04 And we’ll look at the result.
08:08 Shift + Ctrl + E gets us the whole image.
08:13 And when I press 1, I get 100% zoom.
08:19 Now we can look around in the image to see if we have any really disturbing or distracting stuff. But I personally think it worked out well.
08:32 Next step is Sharpening.
08:35 My lens is quite good and my camera too. But we have manipulated the image. So it has to be sharpened a bit.
08:49 I will select Filters
08:53 and click on Enhance and here is Sharpening. I could also use the Unsharp mask which is very powerful sharpening tool. But for now, Sharpening is enough.
09:06 This tool has basically only one option which is the sharpness slider. It can be adjusted and its enough for such an image.
09:16 This is the unsharpened image and when I drag this slider, the image gets sharpened more and more. You get a very funny effect if you slide it too far.
09:31 I think for this image this value is good.
09:38 The hair looks clearer now but here you can see some blending or distortion.
09:46 So, we will slide it down and this is better.
09:52 I would like to go for soft effects rather than have any distortion in the image.
10:00 They are the proof that you have manipulated the image.
10:06 So, let's look at the result.
10:09 It looks quite good.
10:11 And now the last step is Saving this image.
10:15 I will go to File and click on Save As and just change the original file extension ‘tif’ to ‘jpg’
10:29 and click on the Save button.
10:32 I get a warning that the JPEG can't handle images with multiple layers. Ok. So we have to export them.
10:44 I think 85%is a good standard value for this image.
10:53 So I have saved this image as JPEG image here.
11:01 You can look at it in full screen.
11:04 This is it. The first tutorial of Meet the GIMP. In future tutorials, I will cover topics like how to set up GIMP, how to draw, convert, etc. and tools and many more.
