The only way to get the full dynamic range out in a render or bake is to save it as an EXR float from Blender. Not even saving 16-Bit PNG float will keep all the information in the highlights in Blender. But many applications call for another format other than EXR. Such as PNGs and even Jpegs.
So is there a way to compress the full dynamic range information from the EXR into a 8-bit PNG using Gimp? So basically all the HDR info in the EXR file can be seen in a 8-bit PNG and the highlights are not blown and the shadows are not crushed. In video, Log does basically that. Squeeze the dynamic range which normally couldn’t be handled by Rec709 into rec709.
Anybody knows how to do that with EXR to 8-bit PNG in Gimp? Again, I’m aware of the limitations of 8-bit PNG, but this is what I need to output to. So my question is really how to compress the dynamic range to fit the 8-bit limit.
I opened the Bump Map dialog, then tried to choose an existent layer through the spinner (Presets , however, I didn't found in the Presets field despite I have layers that I already created. Confusing, I need to point this layer so I can work on.
I'm trying to create a texture mask for a game map, and need to select the cliffs on my terrain. How can I select the areas where the pixel value is substantially different from adjacent pixels by a certain amount?
Need Scottish fabric in your graphic composition? Tartanmaker can help you : http://www.tartanmaker.com/?page=index. The result is available as png file.
Backgrounds. No idea ? This site can help you : http://bg.siteorigin.com. The user have control over any colour, many patterns, blend mode, pattern intensity, noise, invert the pattern and scale it up 2 times. The result can be saved as a png file. Pay attention, the file is saved as file.png'. So you have to delete the ' in the extension so you can use the file in gimp to further pimp the creation.
After some great help from this forum I've nailed down my Gimp plugins and bash shell commands. However I want to launch them from a shell script and they're failing from there.

Any thoughts on what I could do differently?
Starting with "open" at the beginning doesn't work because then it treats my command line parameters as parameters for "open" and not for Gimp.
I set out on the task, as described in the Subject Line, to modify an 8 x 8 -points subject. I find that I not only misunderstand those methods, but can't even isolate the pixels of interest.
I have some familiarity with Color Mapping, Color Exchange, Rotation, Levels, Colorize, etc. But I'll be damned if I can operate on ONLY the intended region.
The attached 1) Starting Point shows a Grays 'center dot', which I seek to shift to Greens.
I wish to affect only the region depicted in 2) Intended Selection, selected via Select > By Color.
When 3) Copied, and Pasted as New Image - Alpha blend is evident, which is grand, as the shading is intact. But so is there a shaded background, which I wish to exclude, as depicted in
4a) But so is background, bleeding through - Untitled, and
4b) But so is background, bleeding through - Untitled.png
– – –
I've a feeling I needn't even extract that center-dot as a separate 'frame' to work in, but that would seem irrelevant –– when I get it shifted to Greens, I'll just paste it back in the Starting Point image.
What is it[s] I'm missing about simply selecting a region, to copy-and-paste, for modification. Why is the background haunting me, and won't let go?
Also, any hints on the overall objective are warmly welcomed.
I need help with the resynthesizer plug-in and in particular Heal transparency code. It works perfectly fine with all my images except for a new batch that i received recently. The error and messages are: GIMP Message:

Plug-in crashed: "resynthesizer" (/home/ariotta/.config/GIMP/2.10/plug-ins/resynthesizer) The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.
