|Welcome to Meet the GIMP.
|-
|00:24
|My name is Rolf Steinort and I am recording this in Bremen, Northern Germany.
|-
|00:30
|I wanted to do a video podcast about the GIMP.
|-
|00:33
|The GIMP is the very powerful image manipulation program.
|-
|00:36
|It is a free and open source software and it runs on Linux, Windows and Mac Operating Systems.
|-
|00:46
|It is an open source equivalent of the popular graphics editing program - Photoshop.
|-
|00:54
|The GIMP is maintained and enhanced by a group of dedicated volunteers and has provided me with the means to post and process my photographs on the Linux computer.
|-
|1:05
|Now I want to give something back.
|-
|1:07
|I am not very good at coding and hence cannot contribute on that way.
|-
|1:13
|But I am a teacher by profession and hence I can teach others to use GIMP.
|-
|1:18
|First I thought about writing tutorials. But John Arnold's ‘Photo Walks Through’ inspired me to use screen-casting to create video tutorials.
|-
|1:27
|In this 1st tutorial, I want to give you a small tour of GIMP and its features. I will briefly demonstrate how to prepare an image for the web.
|-
|1:35
|I will give detailed explanations in future tutorials.
|-
|1:40
|To open an image, I will just drag and drop the image on the tool box.
|-
|1:45
|And here it is!
|-
|1:49
|Let’s have a look at this image.
|-
|1:52
|I shot this at the market place in Bremen. You saw other images of that during the introduction.
|-
|1:59
|There are always tourist shooting pictures of our town hall.
|-
|2:03
|And I caught this funny moment where 3 people were shooting the town hall with cameras in front of their faces.
|-
|2:13
|I want to make this image ready for the web.
|-
|2:18
|Lets see what I can do with it.
|-
|2:20
|First the image is tilted so I have to rotate it a bit.
|-
|2:25
|Then I want to crop it to remove this part - the back of a person.
|-
|2:32
|The 3rd thing I want to do is to bring in more colors and contrast.
|-
|2:41
|I also want to re-size the image because now its nearly 4000 pixels wide, which is far too much.
|-
|2:50
|And then I want to sharpen it and save it as a JPEG image.
|-
|2:57
|Let’s start with rotating.
|-
|2:59
|I zoom into the part of the image where it is most obvious that the image is tilted. You can see it here.
|-
|3:08
|By the way, you can move around in the image by pressing Space and just moving the cursor.
|-
|3:18
|And now I choose the Rotate tool by clicking here.
|-
|3:22
|In the Rotate tool, there are some options set by default to values suited for graphical work and not for photographic work.
|-
|3:34
|So here Direction is set to Normal(Forward) but I will set it to Corrective(Backward).
|-
|3:38
|I check if I have the best Interpolation. So that's fine.
|-
|3:43
|And in the Preview grid I choose Grid instead of Image.
|-
|3:49
|I shall increase the no. of grid lines by moving the slider. You will see it soon.
|-
|3:57
|Now I will click on the image and get a grid overlaid over the image.
|-
|4:05
|This grid is straight.
|-
|4:10
|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.
|-
|4:23
|Let me demonstrate. I will rotate the grid like this.
|-
|4:28
|I will check the other part of the image to make sure.
|-
|4:32
|Looks good to me.
|-
|4:36
|Now I will click on the Rotate button.
|-
|4:40
|This will take some time since the image is about 10 mega-pixels
|-
|4:49
|And its done!
|-
|4:54
|The image has rotated.
|-
|4:56
|Lets have a look at the whole picture. Shift + Ctrl + E brings us back to the image. And here it is!
|-
|5:05
|Next step is Cropping.
|-
|5:07
|I chose the Crop tool by clicking here.
|-
|5:11
|I want to keep the aspect ratio of the image as 3:2.
|-
|5:16
|For that I check Fixed Aspect ratio here and type in 3:2.
|-
|5:26
|Just clicking to come out of that box.
|-
|5:29
|And now, I can start cropping.
|-
|5:35
|I want to include the feet of this person here but exclude this part of the image.
|-
|5:42
|So I start here at this point and pressing the left mouse button, I drag upward towards the left to select the area.
|-
|5:51
|Note that the aspect ratio is constant.
|-
|5:56
|And now I have to decide how far to drag.
|-
|6:02
|I think this is quite good.
|-
|6:08
|Let’s checks the borders.
|-
|6:11
|We have excluded this part. There is a person sitting here.
|-
|6:18
|I think there is enough room here for the person to be in the picture.
|-
|6:25
|So I will leave it that way since it looks nice.
|-
|6:31
|There are windows here on the top.
|-
|6:34
|And there is enough of them in the image to see them as windows.
|-
|6:40
|But I think there is not enough room around here at the feet.
|-
|6:43
|So I'll just click on the image, left-click on the mouse and drag it a bit down.
|-
|6:50
|I think this is good now.
|-
|6:53
|But now there is not enough windows seen here and the person seated here is very near to the border.
|-
|7:00
|So lets make the image a bit larger.
|-
|7:06
|We are running into a problem here. Perhaps you can see it.
|-
|7:13
|This happened during the rotation.
|-
|7:19
|There is a small part here which is transparent now.
|-
|7:24
|I don’t want to include that, so lets go back to Crop tool.
|-
|7:33
|I want a bit more room here; so I am dragging this up.
|-
|7:41
|Not so far.
|-
|7:46
|I think this is quite good.
|-
|7:49
|Now just click on the image and here we have the cropped & rotated image.
|-
|7:56
|Shift + Ctrl + E brings us back to the full view.
|-
|8:03
|Next step is to boost the colors & contrast a bit.
|-
|8:09
|There are several ways here. I could use the color levels - here it is, the curves or some sliders.
|-
|8:22
|But I will try doing this with layers.
|-
|8:27
|I simply make a copy of this layer here.
|-
|8:32
|And change the layer mode to Overlay.
|-
|8:39
|And you can see its a very strong effect. I don’t want to have it that much.
|-
|8:45
|So I slide the opacity slider down to a value where I think its looking good.
|-
|8:59
|Little more perhaps.
|-
|9:02
|Ok, I think this is good enough.
|-
|9:06
|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'.
|-
|9:20
|Then all the changes become permanent.
|-
|9:23
|Except if I go into History here and go back and undo the history.
|-
|9:30
|But we’ll cover that later.
|-
|9:34
|Next step is Resizing.
|-
|9:37
|I will click on the Image menu & select Scale Image option.
|-
|9:48
|Here I will just type in 800 pixels.
|-
|9:59
|And I get the value for the height automatically.
|-
|10:04
|When I unlock this link here, I could distort the image while re-sizing it.
|-
|10:11
|Interpolation.
|-
|10:14
|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.
|-
|10:31
|Now click on Scale.
|-
|10:35
|And we’ll look at the result
|-
|10:39
|Shift + Ctrl + E gets us the whole image.
|-
|10:44
|And when I press 1, I get 100% zoom.
|-
|10:51
|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.
|-
|11:10
|Next step is Sharpening.
|-
|11:17
|My lens is quite good and my camera too. But we have manipulated the image. So it has to be sharpened a bit.
|-
|11:28
|I will select Filters and click on Enhance and here is Sharpen. I could also use the Unsharp mask which is very powerful sharpening tool. But for now, Sharpen is enough.
|-
|11:49
|This tool has basically only one option which is the sharpness slider. It can be adjusted and its enough for such an image.
|-
|12:07
|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.
|-
|12:23
|I think for this image this value is good.
|-
|12:30
|The hair looks clearer now but here you can see some bleeding or distortion.
|-
|12:38
|So we will slide it down and this is better.
|-
|12:44
|I would like to go for soft effects rather than have any distortion in the image.
|-
|12:52
|They are proof that you have manipulated the image.
|-
|12:58
|So lets look at the result.
|-
|13:05
|It looks quite good.
|-
|13:09
|And now the last step is Saving this image.
|-
|13:13
|I will go to File and click on Save As and just change the original file extension ‘tif’ to ‘jpg’
|-
|13:27
|and Click on the Save button.
|-
|13:30
|I get a warning that the JPEG can't handle images with multiple layers. Ok. So we have to export them.
|-
|13:42
|I think 85%is a good standard value for this image.
|-
|13:51
|So I have saved this image as JPEG image here.
|-
|13:59
|You can look at it in full screen.
|-
|14:03
|Here it is.
|-
|14:05
|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.
