G’MIC is a lot of things that do stuff with images. You have a stand alone program with a complete image manipulation and analysis programming language, an online service and a GIMP plugin that gives easy access to (nearly) the whole package. Don’t get G’MIC from other sources than their pages – the update cycle is so fast that package maintainers can’t keep up. The version recorded in the video is already outdated twice at the time of the publication.
The second part of the video is a promotion for Ramón Miranda‘s very good training DVD “Muses”. It goes through the whole process of learning Krita – a graphics program under Linux and Windows, which is much better for painters than GIMP – up to finishing a real digital painting. You can buy the DVD at the Krita shop, 32.50€ is comparable to other kinds of such DVDs and the proceeds support the Krita Foundation.
I got this one for free – and I will give it away! If you want to have it, write a comment to this blog post before Episode 200 is published. Get your mail address right (it will only be visible to me) and mention that you want the DVD. After the deadline I’ll have some supposedly innocent children draw a winner.

“darktable is an open source photography workflow application and RAW developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.”
I cant say it better than this bit from their page.
These 42 minutes are a rigorously cut down version of my nearly 2 hours long walk through darktable – I was distracted so much by the endless modules and possibilities that I forgot the time. This will not be my last darktable video, I’ll try to focus a bit more on usable stuff in them. 😉
You can find Pascal’s videos at pcode.nl, you have to search a bit for them.

This week nachbarnebenan shows how to use the KDE (and Windows) photo organizer digiKam. There is more to it, a second part will follow. I don’t know much about digiKam because I use Gnome Shell as my desktop environment and digiKam is made for KDE. It would run on my system, but I would have to install a lot of other stuff too. Linux users have a lot of desktop environments to choose from.

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!

29:55 5 Years – a summary.
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
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.
If you want to become a member of the forum, just drop me a mail at email@example.com and tell me your intended user name.

It’s time for a guest again. Nachbarnebenan shows how to process a RAW image in the current (well, it was November…) version of Photivo. Photivo has a very different approach to image processing from GIMP and others. It’s more stacking up and tweaking of algorithms instead of making a series of changes one after the other. Fully non destructive and very powerful.
To isolate the model from the a bit to vivid background Nachbarnebenan produces 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 the next episode he will show how to combine these two images in GIMP into one.
I tackle a question I was asked at the 28c3. Is there a way to draw geometric figures in GIMP? Well, I found three.
The selection tools provide a variety of ways to make a geometric selection which later can be stroked or filled with a colour or pattern. The paths tool can be handy too, I didn’t cover it in this show.
The Gfig plugin allows the construction and editing of such figures, but there are a lot of drawbacks and some risk of fatal crashes.
And finally – is GIMP the right tool? Why not take Inkscape, dabble a bit and export the result to GIMP? Inkscape is easy to use for simple tasks – they have a really good user interface. For more complicated stuff there are the tutorials at screencasters.com. Long time no show there, but perhaps Richard and heathenx can be pestered into making some more. They haven’t given up but gone into hibernation a bit.
