| 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.
h |
| 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. |
| 01:02the | 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.
C |
| 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 here. 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.
C |
| 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. |
| 06:11d | 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. |
