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.
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!

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. If you want to compile 2.9 on Debian, here is a How To in our Wiki. (The link address says still 2.7, but it is 2.9….)

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.

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.
UPDATE Mar 18: There is a nice way to use the histogram with selections. Select the dark region and look at the histogram – it shows only the data from the selection. The histogram tool is “selection-sensitive”.

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

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.

To get something festive to drink over the holidays I have ordered a special MTG-Beer from a brewery. It’s finest Pils in a can with Wilber on it! (Why a can and not a bottle – there is no “Make a Bottle Filter” in GIMP.)
In this episode I explore the Map to Object filter. It can render an image on a plane, a box, a sphere and a cylinder. The default dimensions of the cylinder are that of a beer can. Quite significant insight into the world of programmers. (BTW, the box preset is a cube, not a pizza box…..)
But before that is a look back onto the last show. Saul Goode shows a much easier way to generate patterns with the clipboard and I explain how I got the dots of different sizes in the blog image.
For all of you a happy holiday!
I hope to be back still in this year, so I’ll keep the new year wishes for later. As a distraction the 28c3 is coming up 10 minutes away from my home. I got no tickets but hope to get in there at night and watch some stream on the day.
