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 the 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 | Lets 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 | Lets 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 checks 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 is 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 is 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. |
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 layer 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 lets 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. |
