A nice feature crept into GIMP 2.7 under my Radar – presets for the tools in the toolbox. You can store all the settings, give them a name and recall them later. I show how to make some for rotating an image and cropping in different aspect ratios. GIMP 2.7 includes also a system for tagging brushes. A combination of tags and presets allows a big but manageable collection of special brushes. This needs further exploring. Then I have to brag about the low light capabilities my new X100 – ISO 2000 and nearly no noise. There is no torrent file for the moment, because we still have to resolve these tracker issues. And beware of the companion file – I think it is only useful for you if you want to tinker with the RAW file or check out an image out of a X100.

The last episode was for absolute beginners, this one is for Geeks. I try to explain (and understand on the way) how images are stored in PNG and JPEG files. PNG (pronounced “PING”) does this lossless, the image can be retrieved in the same quality as the original. PNG works wonders with graphics with a lot of lines and clear colour areas, comics and logos for example, but it creates monster files out of photos and similar images. JPEG looses details, aquires artefacts and generally mangles the image. But it has so beautifully small files and the losses are in most cases invisible – except in the area where PNG is good. So both have their niche to live in. How is this done? I try to explain this without the math, using analogies, plaing with GIMP to reenact some stages and reducing the complexity a lot. If you want to know the exact facts, read up in Wikipedia, which was also my source of information, or look for other sources. I hope that I never crossed the border between simplification and telling wrong stuff – but I am really not sure. The math is really over my head, last time I had to tackle such a level a Pentax ME Super was still a new camera model. I am happy about any comments that improve my understanding – and all other comments too.

This is an episode completely in “Beginners Level”, some of you have asked for such a thing. I go through the editing of an image and cover a lot of topics. Nothing really in depth, but you should be able to work your way through other material after viewing this one. I start with a short tour through the user interface of GIMP, you find more about that in the GIMP documentation and other places. In between there is a bit about saving vs. exporting an image – without the nasty and pointless discussion. The image itself has to be rotated a bit, cropped, treated with a bit of curves, burned, and dodged, given more omphh with a layer in overlay mode that of course has to be modified with a layer mask. Finally the image will be scaled down, sharpened and exported as a JPEG while the original XCF file is conserved. Quite a tour – so I needed nearly an hour .

This episode is about using GAP, the GIMP Animation Package, and “The Book of GIMP”. I walk through one of the tutorials of the book and create a multi layered animation that will be used in a cleaned up form for these videos. I can not praise the book enough, you can read more in a former blog post. GAP showed some flaws, but this may be the problem of the Debian package that I used. “The Book of GIMP” has also a reference part. I compare that to the official GIMP documentation while looking for information about the Convolution Matrix. Before all that I tell you about a GIMP plugin for exporting a layer as a PDF file and I defend my new camera – 36 Megapixels may not be too much, they only show the limits of the lenses….. Cameras with smaller sensor sizes of course hit a barrier with more and more MP. The next episode will have animated lower thirds and a proper automatically generated title screen. ;-)

The last episode got a lot of comments – thank you all for them! And in this episode I try to follow all of the tips you gave me. I remember layer groups and drop shadows, see that Alpha to selection is really better and fight with Copy%Paste in the text tool. I got a present too – a fine script in Scheme for generating the title screen. Of course that has to be explored. Did you know that you can export the content of a selection as a new image by key stroke? I found out about SHIFT-CTRL-V. Saul’s script gets also a first analytical look – Scheme looses its terror if you come close. Matthias pointed to an other Colour Design site and the GIMP Magazine will publish a new issue next week. And finally I take a good look at the “Blender Master Class”, a very fine book about the 3D software Blender.

Long time no show – but this project is not dead. For the fresh start a new design for the intro is needed. And a new design needs new colours. I used the Colorschemedesigner to create a palette of colours fitting the “Original MTG Orange” from the logo. Clever algorithms use old artists knowledge about colour combinations. This site even exports a GIMP palette file which is then imported into GIMP. For the lettering I wanted some fresh fonts and found them at the League of Movable Type.

I gave myself a real photo printer for the 5th anniversary of “Meet the GIMP!” and have now my work-flow ready to print in the “right” colors. One reason I shied away from printing for years were the costs. Original Printer Ink is one of the most costly fluids that are traded commercially (1544.54€/l (1) is not the highest price you can pay) and good paper is expensive. But now I have found a combination of a good printer, which is subsidized by small and expensive ink tanks and a good second party ink for 1/6 of the price. The ink is pigment based and so doesn’t bleach out in the light so fast as dye inks. Added to that two good but cheap papers for making beginners mistakes. Of course the colors are off when I print with the usual TurboPrint driver. TurboPrint knows neither ink nor papers. So I needed two printer profiles – one of them was already payed for with the ink starter set. Well, I had to buy two more profiles because I had made a big mistake while printing the test sheets. Take care to switch off all color correction while printing calibration charts. With the right ICC profiles GIMP can give you a Soft Proof of the image that is going to be printed. The look of the printed image is simulated on the screen and you can adapt the image to get your best result. All you need to know (and much more) about calibration and the different “intents” is at Cambridge in Colour and at the Idea Machine. (1) It’s even worse than I said in the video. The ink cartridge holds 11ml and costs 16.99€ Epson list price. That’s 1544.54 per liter. farbenwerk C7 runs up to 275€/l in the set and 230€/l for the ink only. Quite a difference.

I found a new feature in GIMP, no idea how long it has been hidden in the files menue. One can import a whole web page in one image! Better than a screen shot, because you don’t need to scroll down. The web site of the GIMP Magazine results in an image of 1024×16037 pixels, quite an extreme portrait format. It doesn’t work with all sites and sometimes results in render errors. But it is a nice tool. The GIMP Magazine will have it’s launch in some days on September 5, you should know this by now. ;-) I helped a bit publishing a book, working as a Technical Reviewer. I got the drafts of all the chapters as a Libre Office File and worked through it, filling it up with nasty comments. So I can claim that I have read every word in Michael J. Hammel’s book “Artist’s Guide to GIMP, 2nd Edition” that I have on the lab bench in the second part of the video. It is not a text book but a collection of small and medium sized projects. You learn by doing stuff. Of course I am a little bit biased, got some money, fun and a box of books, but I would also have recommended the first edition of this book. And the second one is better! The TOC Not really needed here – the show starts with creating an image from a web site and switches over to the book review at 7:40. Nothing more in it.

In the last episode was a short segment about the brush dynamics in Ramon Miranda’s GIMP Paint Studio. I wanted to read up a bit about this, but the GIMP documentation hasn’t held step with the development here. So this video shows my exploration of the brush dynamics control. The possibilities are limitless, it seems. The show starts with another GIMP theme by samj and a big misunderstanding. You can find everything about it at Gimp Chat.

It’s a special day today, five years ago I rolled out the very first episode of “Meet the GIMP!”. And now it is #182, that’s 0.7 episodes per week. ;-) But the show starts with an other anniversary. Twenty years ago these days Tim Berners-Lee (still without a “Sir” in front of his name) published the first photo on the World Wide Web. Up to then it had spent it’s first year or so text only. The users and servers were somehow connected to the CERN particle collider near Geneva. What’s better to put on an image in a nerdy environment than a band? An all female High Energy Rock Band, Les Horribles Cernettes, of course. So a quick and dirty Photoshop (Version 1) hack (yes, web sites were that ugly once…) intended as a base for an in house CD publication found it’s way to the computer of Berners-Lee and history was on it’s way. There seems to be quite a dispute about this just now. Why can’t people keep proper records when they are making history? ;-) Some epsiodes of Meet the GIMP! have found their way into an education program of the Indian Institute of Technology in Mumbai (Bombay). They dub them with Indian English and publish them on their server. The project Spoken Tutorial is a great way to reach out and broaden education. And of course I am proud that my material is used that way. I love the Greyscale Icon Theme by Eckhard M. Jäger of the “Linux for Designers” blog. Keeping the active icon in color is a nice touch. Ramon Miranda has updated his GIMP Paint Studio. This is a collection of brushes, patterns, gradients and more, bound together by presets and dynamic settings for tablet users. (If you don’t have a tablet, get one now!) The GIMP Magazine is taking up steam. I have seen the drafts, they are nearly complete and get better all the time. Expect the first issue in early September. And finally I process an image of a small part of the steam engine 01 1066, which I found in the Hamburg Main Station. The processing is nothing spectacular, just cropping, curves, a bit of burning and dodging. But this time I am printing the image on my brand new printer – an Epson 1500W. An Episode about printing is coming up, just now I am just playing around. A big thank you to all of you for the support in these five years!

In the last Episode I looked under the hood of JP(E)G and PNG. This time it gets a bit more practical – which is better for what? I tackle two examples from the GIMP Magazine web site and test, if they would be better saved as JPG or PNG. The Plugin “Save for Web” is really usefull for this task.(The image for this blog entry is a PNG by the way, showing JPG compression artifacts. As a JPG it would be five times the size. ) I “developed” a method for comparing two layers – just set the top layer mode to “difference”, make a new layer from visible and check that with the threshold tool for pixels, that are not completely black. After locating the problematic zones in an image with this tool, one can decide what settings are “good enough”. Conclusion: It depends. It depends on the file, your use case, your level of “good enough” and your compassion for people on a mobile device in EDGE-Hell. The show starts with a little extension of the last show, Pascal mentioned some options for saving a JPG file that I had overlooked.

A week of news: GIMP 2.8 is out, we have again a modern stable version of GIMP. Gratulation to the developers, this was good and hard work. But instead of relaxing a bit they threw at the same moment Version 2.9 into the world. High bit depth, not only the 16 bits everybody wanted, 32 bits integer and floating point modes are suddenly available. But be aware, this is a field of bugs and crashes, don’t expect any productive results yet. In a first look at 2.8 I show the shiny new brushes, explain how to use the new sliders and the tagging system for brushes, gradients and patterns. For the lazy I add a bit of calculations in input fields. Then nachbarnebenan takes you for a tour through 2.9, presenting the lossless operation of the layer stack and other stuff. But again, this is not for the faint at heart.

Tuxpaint is a painting software for kids between 3 and 100+. Well, the targeted audience ends at an age of 12, but it is still fun to use when you are older. Tuxpaint is available for Linux, Mac OS X and all Windows flavours. Of course it is under the GPL and so free to get and to be shared. The ease of use beats everything I have seen in the professional educational market and I am considering to get it into my school. The user interface and availability of tools in Tuxpaint can be configured to adapt to the skill level of the user and the level of annoyance the environment is willing to tolerate. There are nice sound effects, but how often can you stand “QUAAAAAAAKQUAAAAAAAKQUAAAAAAAK DUCK”? Also printing can be disabled because space on the fridge and ink cartridges have limits. The configuration is done with a separate program which can be kept outside of the reach of the little end-user. The show starts and ends with some information about the upcoming GIMP Magazine. I am somehow involved in the team now but I promise to keep my priorities on this project here. And then there is an invasion of goats int GIMP and 16 bits and more are in reach.

I am on my way to a class trip an so you get only a short episode about the corners and edges around the canvas. There is a menu button, a zoom mode button, a navigator and the quick mask for selections. And of course there are the rulers with the guides and control points to pull out. All this after a quick update on the histogram from the last show.

You are in for a night-time trip to one of the most secret places on the earth – until 23 years ago. The former Stasi headquarter is only 2 subway stations east of my home and I quite like the morbid, spooky atmosphere there. It’s a really huge areal, lots of office space and other buildings. Some of them are used as a museum and as the archive for all the Stasi files. Others are rented out or are simply empty. My image missed some details in the shadows. I used a modified “burn with a layer in Overlay Mode” technique to get a bit of light into them. Instead of painting on the layer I used the L-part of the LAB colour model. I got the idea for this from the Darktable Blog.

Nachbarnebenan continues his tutorial from the last episode. He isolated his model from the a bit to vivid background by making two images from his RAW file. One is crisp and colourful – best for the model. The other one is soft and a bit dull – this tones the background down. In this episode he combines them to one image with a layer mask. Did you know that there is a filter in GIMP to emulate the look of an image for colour blind people? Nachbarnebenan shows how to use it. It’s no so important for photography – but think of all the graphics work done with GIMP. By using this filter you can make a difference in accessibility If you want to get into programming plugins for GIMP in Python – there is link to this great HD video from Gimpusers.com. And for the next episode you’ll need a Trench coat and dark glasses – we’ll enter the Stasi headquaters at night. Sorry, no TOC up to now, but at around 15:30 is the great segment about GIMP and colour blindness.
