Patrick runs a Blog about uninteresting things like photography, Open Source programs for photographers and graphics enthusiasts and other boring stuff. A recent five part series about the conversion of digital images into Black & White is especially to be avoided. I want to steal some of that stuff and you are not supposed to notice.
So, please don’t click on these links above and wait patiently for the next episode of Meet the GIMP. Intended release is on Feb 12 2013, it’s recorded and about half way through the editing process.

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.
[...] 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.
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!
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.
Great news, just CTRL-C CTRL-V from a mail form Steve:

(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.
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
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:
STAY AWAY FROM THEM!
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.
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.

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.
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 engine01 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!
