Someone in Russia with the IP 23.142.32.11 is constantly downloading this file. More than 10000 times today. 
I have pulled the video off the server until the situation returns to normal. PLEASE KEEP AN EYE AT YOUR DOWNLOAD DAEMONS! (Download Master in this case).
In this first Epsiode of the second year of Meet the GiMP! I return to Cakovec, Croatia with an image from the old castle. For celebrations I made a double length show. 
And to celebrate the Croatian style weather here (30+C), I had the windows open and you get some street noises. Our weather is mostly so cold that only bigger shops have an AC.
Before Croatia there is an update on the Old Ink Challenge from the last show. You can download the new set of images and try your knowledge of GiMP (or any other free software program) on that. Please send the results to info@meetthegimp.org.
Of course the new Forum gets a place too in this show. Have a look!
Then I reveal the secret of painting without gaps or overlaps – to answer a question from Luis in Buenos Aires.
In Cakovec I take you with me while I shoot the image to postprocess and tell you a secret of a lot of better photographers than me: MOVE!
The postprocessing involves mostly stuff I had already covered. New is an enhancement of the sky with a masked layer in multiply mode.
A team of highly trained Penguins in the MTG-Labs invented a new TLA, the TOC. And here it is:
The Old Ink Challenge 0:40
The new forum 7:00
Painting without overlap or gaps 10:50
How to shoot a castle 15:20
Postprocessing the castle image 18:20
Rotate 18:50
Crop 20:30
Clone a powerline out 24:20
Boosting the colours with curves 31:10
Enhance the sky with a masked layer in multiply mode 33:00
Now you can skip the parts of the video you don’t like.
Edit: With an audience like you a podcaster can be lazy:

I shot some autumn scenes with a Lensbaby in a very mixed light condition. And I haven’t checked the histogram after this shot. It is the only one with the focus right on spot and a dreamy flair. The leaf in the center was overexposed in the JPG image – blown out highlights ruined the image.
This is the final image – not the one with the blown out highlights….
But I had shot in JPG and NEF (Nikon’s RAW) – so I used UFRaw to produce a TIFF file with the right exposure of the leaf and blended it into the image with a layer mask. This is basically the way (pseudo-) HDR works. Take different parts of the image from differntly exposed photographs.
A slight correction with the hue/saturation tool was necessary to adjust the colours. Cropping was done twice – a mistake made a correction necessary. So I covered some advanced options in cropping.
I promised some links:
Don’t forget to make a triptych and post it in the photogroup. I’ll draw a winner for the one year 23Plus membership sponsored by 23 in show 16. So you have still time to Oct. 18 to submit an entry. The pictures there are already worth to be looked at.

You are in for a mix of topics in this screencast.
I start with answering the first comment I got 
and show some ways how to get the GIMP 2.3 for different operating systems.
The site I mention in the podcast is www.gimpusers.de. EDIT: There is an english version of that site under www.gimpusers.com. The Mac stuff is at gimp.org.
Then I begin to work at an image of a ship coming down the river Weser on a foggy morning. The image is mostly gray and very low in contrast. As this was shot in RAW, it is possible to get something usuable out of it. You get a lecture about the difference of 256 steps between black and white in JPEG and why the 4096 steps in RAW are better.
(I assume there would be more detail in an JPEG out of the camera because it does some postprocessing…)
I show how to access the menues of the GIMP in three different ways, how to analyze an image with the histogram tool and the colour picker, how to rotate an image just a little bit and how to crop it using the Rule of Thirds (not a LAW – but a nice rule of thumb) to get an aesthetic result. And I nearly forgot to save the image in GIMP’s native image format – XCF.
Please let me know what you think about the show. Too slow? Too fast? Too much ramblings? Or too much information? Even if you like everything – write a comment or drop me a mail at info@meetthegimp.org

In this first episode I show how to get an image ready for the web.
In a quick tour I cover rotating, cropping, pushing the colours, downscaling and sharpening to show a bit what the GIMP can do.
