Life threw some interesting stuff in my direction – mostly positive – that consumed a lot of my time and attention. But now I have some capacity to come back to this project.
It will take some time for the next video. First I have to rebuild my production pipeline – and that is an interestimg task too. My favorite video editor Cinelerra crashes all the time – I have to learn Blender for editing. And then there is the screen recording with a lot of newoptions and some nice new ways to encode video…..
There was no show for quite some time – and there will be a gap until the end of summer. I move back to Bremen – and that takes a lot of time and creativity away. But in Bremen I will have nearly 2 hours more time each day, because I can walk to school and don’t need to ride the famous Berlin S-Bahn Ring Line.
In the meantime I have a challenge for you! Present the place where you live to us – but look down on the sidewalk for that! The best results will be published in the GIMP Magazine #5 and of course here on the blog. The exact rules are below.
This Challenge is a perfect rip off from a challenge by Andrés (Twitter)(Website), an illustrator from Buenos Aires, in the now closed forum of Tips from the Top Floor. Make a mosaik of images of the sidewalks in your city and try to transport the atmosphere.
This is my take on the Silvio-Meier-Strasse around the corner from my flat in Berlin.
Make a mosaic of at least 3×3 images.
All images have to be shot straight down
All images are in the same scale, use the same distance to the ground and the same focal length.
All images have to be linked to each other in their theme by being from one city, one journey …..
Publish your image online and post a link to it before September 1st in the comments to this blog post.
License your image as CC-BY or better and allow this site and the GIMP Magazine to publish your image under CC-BY (here) or CC-BY-SA (GIMP Magazine).
Rules 1 to 4 may be broken, 5, 6 and 7 have to be followed exactly.
You may download the template for my version from above or build your own one. You are free to make other forms than a square – circles or a spiral anyone?
The video uses chapter marks, you can jump between TOC entrys!

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….)

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 am planning an episode about editing images out of cheap cameras and phones. My phone takes technically really decent images and I have given away all my old digital cameras. All I have is too good for this. 😉
If you have an image that is suffering from “not so good” camera quality, either from a phone or a cheap camera, and let me take a shot at it, please mail it to email@example.com or put a link to them in the comments. Thanks!
Legal notice: By sending me the image you give me the rights to use them in the show and publish them in the companion file under under CC BY-SA 3.0 License.
Now I am off to visiting some friends in Bremen. Next show next week!

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.

Meet the GIMP is on Youtube! Mike AKA Eppic has started this channel and is uploading all the old episodes. Thank You!
I need some dot patterns for a project with Moiré. And so this episode is deveted to building dot patterns out of a grid without grid lines. Misterious? Have a look at the video!
The video ends a bit abrupt. Cinelerra went on strike with the last part of the footage. So some stuff is left as an exercise for you!

I need (EDIT: Not now – schedule changes….) some one-time pen pals for my class – more later down in the post.
Fist about the next show. I put way too much time into trying to convert Nachbarnebenan’s Photivo/Gimp video into something that Cinelerra would eat. He has a new microphone, sound is well, tutorial well done – and the framerate changes all the time. No audio sync, wrong sync and at last a version with perfect sync that kills Cinelerra (and the whole system) 5 minutes into the video. I found that out after editing for quite a while – lots to do in the first minutes.
I started to record a show today but put too much on my plate GIMP wise – new try tomorrow.
I have to teach English in my class for some weeks. One lesson only per week, so no big deal. But I got the idea to have the kids answer some real letters from real persons – not only these fake ones out of the text book.
If you want to help me, send my class a short letter from your hometown, perhaps with an image or two in it. The kids are 13 to 14, learning English in their 4th year. Most come from migrant families (Turkish, Arab, Vietnamese), English is their third language. Some are starting to tackle French now too. So please don’t torture them with too high brow English, but they should be able to read more than Kindergarten level. And they have the Oxford dictionary…. 😉
Most of them know basically only Berlin-Neukölln, TV and perhaps the hometown of their parents. Everyday stuff will be interesting for them, your street, your local attractions, where do the kids hang out….
You can mail your contribution as a text editor file (Libre Office can import a lot) or as a pdf to firstname.lastname@example.org . I’ll print that for the kids. Or if you have still envelopes, stamps and so on, write to “Alfred-Nobel-Schule, Klasse 8d, Britzer Damm 164, 12347 Berlin, Germany”.
Of course you’ll get an answer from the kids!
