Episode 187: Cleaning Up

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.


The video now has chapters – you can jump to the TOC entries!

Get a new, great GIMP book for 40% off the regular price!

The review for this book should be in the show that I am finally have started to produce. But my voice is gone due to a really nasty cold and there is a one week 40% discount on this book. You can get a paper copy AND the e-Book or the e-Book in different versions alone.

I have the PDF version sitting around to review for weeks and took now a real look into it. The one on dead trees is still somewhere over the Atlantic.

I love that book. To quote myself from a G+ discussion:

[…] This book here is in part a manual – and a different one from the one at docs.gimp.org. They complement each other like the man pages and a good text book about Linux. It draws connections which are not in the official documentation and explains concepts where docs.gimp explains single functions. Both have their place, like man pages and text book.

I have the pdf here for review at Meet the GIMP (and as I am missing a guy with the cattle prod at the moment haven’t looked deeply into it) and I like very much what I see. It clearly shows that Olivier Lecarme is a very experienced scholar – the book even contains an appendix with the basics about the science of light, color, the perception thereof and the technical background of image editing. And tips for selected exercises throughout the book – work of a professor clearly. He is retired, so no finals to be expected. 😉

And for all on the more northern latitudes – it contains lots of images of lovely Mediterranean scenes, mostly in Olivier’s garden and at least one of a grumpy cat.

I’ll read some parts carefully today (sick at home with a bad cold), but just now after 2 hours of browsing I would say: BUY IT!

If you have missed a comprehensive textbook on GIMP, get this one.

Not sure yet? Have look at one chapter or the table of contents.

(Full disclosure: About a year ago I have helped in the production of a GIMP book by No Starch Press and got nicely paid for that. But I owe them nothing.)

Episode 185: The 52.02 €rror – Printing with Profiles

Download the Video! (36:50 73.4MB)
Download the companion file with my printer profiles! (3.9MB)

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.

Episode 184: Scraping the Web!

Download the Video! (14:04 28.0MB)
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!


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.

Yay, mainstream! – and trojaned GIMP installers

This post describes a malware attack using a malicious download link for GIMP for Windows. You can trust this link, it’s the Source.

And now the WARNING!

(The title and the following text have been stolen by me from Michael Schumacher at the GIMP Developers Mailing List and GIMP Users Mailing List.) 


recently, we’re seeing more and more sign of GIMP becoming mainstream – the availability of several GIMP installers for the Microsoft Windows platforms loaded with trojans is certainly an indication for that.

The most common trojan seems to be InstallIQ. A piece of software that grants the providers of the actual installers plausible deniability because the installers itself is clean, and because the user has to agree to install additional “utilities” during setup.

Case 1:

Step 1: the victim is sent a scam mail pointing to a file at photo-host.net/ (which disguses as a image upload site).

Step 2: the files provided there are .gmp files (huh?)

Step 3: for viewing those files, there’s a link to gimphost.com, where the infected installer is located

Case 2:

Another victim or culprit of a related scam seems to be the gimpshop.com site, which used to host a modifed version of GIMP which resembled the Photoshop UI. Either its original author has gone to the Dark Side, or that site has been taken over by a scammer – it is distributing InstallIQ-infected installers.


If you see any GIMP installer sites which have a fine print with phrases like

“is distributing a modified installer which is different from the original ones”




“the installer is compliant with the original software manufacturer’s policies”

then do the following:


And now it’s me again. InstallIQ seems not to be a trojan but an installer that pays out some money for the hosters. It has the capability to load more software and seems so to be considered a risk to the security of the system.

Episode 182: A Special Day

5 Years of Meet the GIMP!Download the Video! (30:37 61.1MB)
Download the companion file! (65.5MB)
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. 😉 Update: An error corrected below and the comments are working again!

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.

UPDATE I made a blunder here and switched the terms dodging and burning – I got the reminder of proper dark room culture from Saul Goode in the forum.

Burning is letting more light from the enlarger onto the paper (as I told in the show) but as it is a negative projected on light sensitive paper  the image gets darker. So I burned the lower right edge of the image.

Dodging is keeping light away from the paper and so making that part lighter, no light at all would result in unchanged white. I dodged the rust on the fitting in the center of the image.

And here comes the twist. A “burned out sky” is white on the final image because it has been “burned out” the negative, resulting in solid black there. I haven’t been in the dark room lab for decades, perhaps I’ll try it again after the printing fever has gone old. 😉 (BTW, my new pigment ink and refillable replacement cartridges arrived today…. )

A very good demonstration of burning and dodging is done in the film War Photographer about James Nachtwey. Worth watching, even without interest in dark room technique.

A big thank you to all of you for the support in these five years!
