While I agree that something like a clone brish would be nice, I'm not sure it 
would fit within the basic "philosophy" of darktable.

Darktable is basically a parametric editor. That means that /in principle/ any 
edit action touches all pixels (drawn masks are a bit of an exception here).
But, the original image stays untouched: with darktable you create a recipe, 
that's only applied to the image when you export it.

In contrast, photoshop, GIMP, krita are pixel-based editors, allowing you to 
edit a selected area down to a single pixel. They also typically provide 
layers and more selection options. But any edit is immediately applied, after 
a save you cannot get the original image back (unless you have it on a 
separate layer).

So a typical workflow is: import a series of images in Darktable, select, tag 
and class them, and do basic editing (WB, contrast, sharpen, etc.). For the 
few (for me <5%) that require more precise editing that Darktable can't handle 
well, export those to png or tiff, and work on them with a pixel editor (GIMP, 
photoshop, ...).

In this precise case, I'd use the GIMP and work on a copy of the image (on a 
new layer within the GIMP): better control, and easy to compare before and 
after (switch the edited layer off and on). 

(In fact, I use another program, Digikam, to do the first selection, and to add 
captions, tags, etc.: I find the interface more to my liking for the DAM work, 
but I prefer the darktable editing. And darktable imports metadata for tags 
etc. through XMP sidecars without problems. So a full workflow is:
Digikam -> Darktable -> Gimp, with some excursions to Hugin for panoramas
*before* the GIMP).

Yes thanks - I tried them.  The Ellipse didn't really work for me.  The Path 
might to some degree ... but it appears to be quite buggy.  I used it to draw a 
thin rectangle around a scratch.  It moved the rectangle to another area 
somehow.  I had to turn it off.  When I try other smaller spot removals on that 
image somehow the path that I turned off reappears.

Generally speaking I think this area of DT needs tender loving care - a 
significant upgrade.  The rest of the product is outstanding - I much prefer to 
LR.

The "Spot removal" tool also has "elipse" and "path" options, which cover non-
circular areas. While not as flexible as a clone brush, they might help.

[darktable-user] Spot Clone Brush?

[Jason Verlen]

Darktable:

Love this product!

The only weakness I have found is the Spot capability.  Unlike other functions 
in Darktable (such as drawn mask) it does not support a brush.  I am working 
with some old negative scans and some have scratches across the frame.  Trying 
to fix these with cloning one small circle at a time is almost impossible.  LR 
introduced the clone brush in v5.  

Is it possible that Darktable can add this capability?

Thank you for considering this

Best
