darktable overwhelmed [solved]

This file seems to completely overwhelm darktabel. I have made many retouches. And now I can do almost nothing. Does anyone know what the problem is here and how to fix it?
DirektBildKopf.dng (18.0 MB)
DirektBildKopf.dng.xmp (1.2 MB)

Now I have discovered something funny: If I delete the grayed out, unused #105 denoise (profiled) in history by clicking “compreess history stack”, dt becomes half alive again. Is this normal?

Your xmp is massive not sure what you are doing I will try to take a look…

If I compress your history stack (get rid of the dozens and dozens of retouch instances) everything is fine again.

258 entries in the retouch module, each multiple times in the history stack will give darktable some work to do and might even stall your box. Not a memory problem, at least not on my side, it takes, max, 2.5 Gb.

Yes, DT becomes slower with very large history stacks. I have got into the habit of just clicking on compress regularly.

Yes, compress history stack revives dt again. I was already very scared. The cause was that I used retouche for the first time today and clicked back and forth hundreds of times until I finally understood the module. I was also puzzled by the large xmp. Now everything works again, not very snappy, but at least dt is alive again.
Thank you.

This may have changed but there was also a recommendation I believe to only have a certain number of corrections per instance of the retouch module…not sure if this is still true but it could get bogged down so it was I believe suggested that it was better to use multiple instances with not too many individual corrections…someone can support or correct this info…going from memory here…

And there I have another question: Is it possible to set the export with dt so that this image is created in the ratio 4:3, so, a little stretched in length? Now I still do it with Gimp, but if it would go with dt, would be wonderful.

Oh, if only I understood this retouch! I tried wildly and was already very happy that I could retouch, although I did not understand it at all. The instructions also talk about multiple instances, but what does that mean? Does anyone know a good tutorial on this?

No. You can crop or you can resize, you cannot stretch.

Yeah, 64 comes to mind. I’ve tried, in the past, to find the exact number but am not able to. Might be something from the past.

Have a look here:

It might not be clear where to click, so just in case:

True for all the modules.

Thank you
the link describes the instances. Good.
But a beginner like me, who first needs an introduction to retouche. My wild attempts have caused this myriad of entries. What does retouche mean: to add multipe circles?
Or more precisely: If I have to make a hundred retuoches like here: How do I do it correctly?

too bad, but good to know, and good for Gimp, so it doesn’t stay unemployed.

Yes, I knew this icon from other modules. But when should you create a new instance in retouche?

Bruce Williams did a video on the retouch module. An older video but still relevant:

Both @priort and me are rather certain that there is a certain number, but I, at least, cannot recall where I’ve seen/read it. As mentioned in an earlier reply I recall 64.

You can see how many edits (shapes) you’ve created in the module itself (top left. shape: <number>).

Good call… I think something similar…and in any case you can name modules to reflect the area that you are working on and that can help to organize your edit so its not a limitation and you can leverage that approach for organization…

what do these shapes: 258 that I used mean?

I didn’t end up opening the xmp you provided but 258 shapes would be 258 corrections to specific regions of interest…

In addition to Bruces video… @s7habo did at least two videos with multiple edits… portraits for sure in one… they were excellent…

Can you retouch a hundred places in an image without using 100 scales?

You don’t necessarily need scales, simple (clone/heal) changes work most of the time. All is explained in the videos (the ones by s7habo are also more then worth the watch) and in the docs:

https://darktable-org.github.io/dtdocs/en/module-reference/processing-modules/retouch/

Scales are levels of detail. I think 100 is crazy excessive… you can work in each level of detail but it think a total of around 50-100 shapes across all detail levels would be the most you would want to do and for that matter I wonder even if some hardware might crap out sooner and some of course would be better

Check this out…

EDIT and as @Jade_NL mentions you can make corrections without invoking scales…

I think there was also a great example in written form on the v2.6 release blog on the dt website…
