I went to the Libre Graphics Meeting 2014 in Leipzig to get either a boost for my motivation or to find an end for this project. It turned out to be a booster.

It was a really good time – even with missing the first day and the (for me) most interesting talks because I had to work that day. Another day was spent at the Zoo with Pat David and his wife, more time in the coffee room, Milchbars and restaurants. All the time having good conversations and learning a lot.

And then I got the honors of shooting the traditional group image. I assume it was not my track record of famous group pictures but the 36 megapixel resolution of my D800 that led to that decision.

In this episode I cover the post processing of the image and how I blended my previously taken image into the group.

  1. You could have saved a bit of time by re-using the curve settings. Gimp stores them automatically unless a preset is used. This way one can apply the exact same curve operation on more than one layer.

    • But it was not the same curve. There are more than 2 hours between these images, so the light was different.

      Curve presets are a cool thing, you can even name and store them for later use.

  2. I’m using your videos to improve my skills with gimp. I often find myself gessing how to repair photographs but watching an expert using the right tools is much better. I still have a lot to watch but I look often for new entries as I asume the program is always adding new features.

    So, thank you for comming back.

    Regarding the techniques you use in the video I’ve had some trouble finding the wavelet decompose filter. I use LInux Mint Kde and the filter was not included. I tried two methods of installing:

    – copying the folder in /usr/share/gimp/2.0/plugins
    – typing “make” and “make install”.

    Finally the solution was to use de synaptics package manager and install the “gimp-plugin-registry”.

    And, regarding the final sharpening of the image. Why do you use such a complicated method? Is it better than the “sharpening mask”? or the “refocus” tool in digikam? Why?

    • The gimp-plugin-registry has a kind of “best of” from the registry.

      The sharpening with the wavelets gives way more control about the result than the unsharp mask. I don’t know what the refocus tool does, but sharpening is a very deep topic…..

    • The shirt was in my mailbox today – fits perfect and looks terrific.

      A favorable Darktable review is in the pipeline for release tonight or tomorrow morning, have to earn that shirt. 😉

      I haven’t noticed the font problem, perhaps because I missed the font talks and went to the Zoo instead. 😉

Anything to add from your side of the computer?
