SEVERE SERVER PROBLEMS! (SOLVED)

Wednesday, May 28th, 2008

This server will be cut off the grid on Saturday. Nothing I can do about it.

But I am working with Marcin at a really stable solution. It will take some time but I’ll be back with new videos in some weeks.

If you want to reach me, use meetthegimp@gmail.com

New in 2.5 (2.6) “hybrid polygon/free select tool”!

Saturday, May 24th, 2008

David gowers wrote a comment that I pull to the front page.

Another exciting thing that will be in 2.6 (and the next 2.5 release) is the hybrid polygon/free select tool! It is truly a thing of beauty, the way you can edit it as you go, easily rotate or scale any freehand section by moving an endpoint, or edit a polygonal segment just by moving an endpoint — and no longer requiring the entire selection to be completed in one stroke is also great! It might be an interesting topic to cover as part of a future show.

Anyone who is curious, also, I strongly recommend you get a SVN checkout of the latest GIMP and try it! It’s worth the effort.

I’ll do that - sometime next week.

This week I’ll answer the first search term that led according to the logs someone to „Meet the GIMP!“. “Getting rid of people in GIMP“ was the question. And here, about 9 months later, is the answer.

I took two shots of the same scene with my point and shoot camera to remove some moving cars (the runner shown here was just an accident. But I like the idea and will do a “real” one soon). I used a technique similar to that shown in episode 44, only this time a bit more sophisticated using layer masks instead of the eraser.

But I had no tripod and no beanbag. So unintentionally I moved and rotated the camera between the shots. Registering (adjusting them to a perfect fit) is the largest part of the work to be done. This involves the selection of a point of reference, moving the top layer, setting the centre of rotation and finally rotating the top layer. With more than two layers this has to be repeated for each layer.

I hadn’t thought that this would work out so good and easy. You can just shoot any public place without moving traffic if you make enough images. Imagine a big crossing, all traffic lights red.  ;-) And you don’t need the tripod. OK, it’s better with….

Some links, as promised:

The exhibition in Hannover’s Sprengel Museum and the formidable book from the museum, in German and in English. Helen Levitt in Wikipedia, an interview with her on NPR and some images on “Masters of photography”

The file with the images from the podcast is at the usual spot.

Episode 045: The Right Colours! (nearly…..)

Today there will be something different for your ears first - thanks to John Pazdan. I like his stuff very much!

Inspired by this discussion in the “Meet the GIMP!” Photogroup at 23hq, I tackle the begin- nings of monitor calibration. For an in depth look go to the page of Norman Koren

You can use this web page from Cambridge in Colour for a start. Then there are tools like Monica for correcting your display.

The DQ tool for getting better prints can be found at the site of the Photo Industrie Verband. Scroll down at the right sidebar and you’ll find it at the bottom. (Have I ever told you how much I like pages without the possibility of a direct link…..)

All this can be helpful for the amateur. But keep in mind that it is no replacement for a complete colour managed workflow. If you really need that, then you have to invest in some serious hardware and time for setting that up. Joel Cornuz has a series of articles covering the Linux aspects of colour management. Perhaps some of you can share links to sites for MacOS and Windows.

Multiple TeachersThis week I am absolutely late with the show. I recorded on the weekend and had to find out later, that I had messed up the sound.

As an emergency fill in I made this. It’s a project I wanted to do for a long time - and did now without anny planning and preparation. I even forgot to take a tripod for the video camera with me. But the lab provided a clamp for Erlenmeyer flasks. Worked great. :-)

I got the idea from Allan J. Ager and Simon Taylor from the Tips from the Top Floor Forum.

You can download the four finally used files and a shrinked xcf file as an archive. The full resolution output is here.
