Finally a new episode – I never had one with more obstacles! But here it is. (And now I even have no time for a proper blog post, because I am going on a class trip tomorrow.)

I explore two new features of GIMP 2.7.2 – I am amazed at the progress.

Then I adapt the often used (and often shown here) technique of dodging and burning with a layer mask to fiddeling with the saturation of an image. I don’t recall to have seen this described anywhere – but I am sure I am not the first one to use this. Has someone a link?

EDIT: There is a big difference between this and the dodge and burn technique. Here I did not change the original data, I made some new. More thinking needed.

  1. YEAH! Finally! Glad to see You are back in business :D!

    Seen the show – looks great and I am sure You will find the solutions to Your Cinelerra and Avidemux problems soon.

    Waiting impatiently to see another show!

    Thanks!

  2. I’ve used this technique before, I think it’s mentioned in Akkana Pecks book. However, I avoid lightness and saturation changes in Gimp as far as possible and do them in ufraw, masking the layers afterwards.

  4. Good to see you’re back on track! :)

    Unfortunately, it seems that the layer groups are still merely a way to clean up the layer stack – not much more. Everything you did with the group would have worked in absolutely the same way without it. No work saved – you even still need the same mask for every single layer (you already said it). However, how do different layer modes within a single group work now? Is this finally in there? You used the first layer in normal mode, the second one in overlay mode. Are you sure the group behaves as expected? In former versions the whole group was set to overlay then – meaning the normal mode layer was only working within this group as normal. What happens if you paint below the group onto the lock? Is it still covered by the normal mode layer or can you see the paint strokes?
    Sorry, I can’t test it by myself for the moment. Using 2.6 again due to some problems with 2.7. Looking forward to you installation instructions :)

    I also have some struggles with the saturation method you’ve used. Since I expect some discussion I’ve created a forum topic: http://forum.meetthegimp.org/index.php/topic,1177.new.html

    Very interesting and controversial episode. Thank you! :)

  5. Would be nice if Gimp would start adding some HDR tools, like PSE 9, Corel Photo Pro X3, Photo Plus Pro X4, etcc have . HDR is the latest trend in Photography. And it is getting even more popular as more photographers, both enthusiast and professional, embrace it.

  6. Great episode Rolf. Gimp 2.8 will not be out until mid 2011 from what I have read at gimpusers. . Bummer!. Seems like the developers still have no date set.

  7. Actualy, I receive an error message in russian, but it is mean, that “this is format is not supported by my device”

    I use iTunes embeded in iPad, instead of PC version (there are no iTunes for Linux).

  8. I’ve had the no selection shown issue for quite some time in Gimp 2.6 so it’s nothing new for 2.7. I think it is an issue with my Compiz compositor.
    Ofthen happens after I’ve switched desktops.
    (No, I haven’t repored it and don’t know if there already is a report for it)
    Both in Linux mint 10 and ubuntu, 8.10 & 9.04. (On the same machine)

Anything to add from your side of the computer?
