Sorry, again a “Nerd Show”. I tackle some problems that have come up with the Python script of the last week and show my way to debug and test while making errors. My first error was to take a test case without colours – my script from last week changed all images to greyscale. Then I learn something useful about merging layers in Python. But the top of the show is even more nerdy – the Octave ...

This is the second time I try to get into Python scripting for GIMP. My script in the first show about scripting was simple, just saving some clicks. Now it is more complicated, variables, loops and floating points included. But no parrots! You find a better version of the programs in the companion file. Following a tip in our Forum I included a Undo Group. So the action can be undone, a behavi...

I was out on a photo walk with a GIMPer from Bremen. One of these shots is post processed in this show. Nothing special, just adjusting the colours with a curve in two different parts of the image. Of course a layer with mask is used to separate the different areas and explained again for the new GIMP users. The really new information is about uploading images from F-SPOT to 23 and flickr. You ...

A posting in the forum pointed me to a description of an interesting way to sharpen an image. This Octave Sharpening is useful when you have to do a lot of sharpening and want to avoid the typical halos around the edges. The secret lies in a combination of 4 USM sharpened layers with different opacity. As in the recipe I used an amount of 5 (500% in the Other Program), threshold 0 and 0.5, 1, 2...

A short one this time – I upgraded to Karmic Koala and did a clean install with new partitions and EXT4 file system. And now I am getting the important stuff back on the disk and leave the cruft out. This meant that a lot of the files needed for a proper podcast are still on the external disks. I take a look a the new Folio by Jeff Curto at Lenswork – because it’s an example o...

We had a nice discussion in the forum about how to crop. What shall determine the crop, the output paper format or the content of the image? The two main aspect ratios used in digital cameras are 2:3 and 3:4. This has technical reasons – not artistic considerations. Then there is a flood of different formats for papers, from ancient to the modern A-series. The big question: How ...

There are a lot of tutorials out there for “The Other Program”, also called Adobe(R) Photoshop(R). (I hope I got the Rs right, can’t find the page where Adobe(R) told the world how to call this program.) A lot of that stuff is easily translated to GIMP, but there are some serious differences. One are the “Adjustment(R) Layers(R)”. This is a way of applying a curve, gradient, hue or saturation c...

The results of the Book Challenge have been so interesting that I have made two shows out of them. This is the second part. If you want to buy Akkana Peck’s book from amazon.com in the US, go to her website and use her link. She gets a bit more money out of it and you pay the same. The TOC 00:50 Threshold tool revisited 02:40 Ityker’s image 04:00 Selective decolorisation 05:00 Layer mask for se...

It’s worth to keep an eye on John Arnold’s Photowalkthrough, perhaps something special is coming up there. The TOC...

If you want to make an incredible amount of money it is a good idea to learn GIMP. Sergey Brin did that, created the logo of his startup and got rich. I downloaded the xcf and peeked under the hood. Just standard stuff – as you have seen by Philippe. The TOC 03:00 Grabbing images from the web 04:30 Elipse select tool 05:00 Copy and paste between images 05:30 Shrink (scale) a layer 07:25 B...
