No, if you create a new instance of the module, the previous work remains applied.
OK, that works … to a degree. It’s seems rather laborious, opening new instances every time. You could easily end up with 20, 30 or more instances.
Also, I just discovered, the previous retouches don’t form part of the image. For example, I was just playing with a cloudy sky. I can clone a cloud, adding it to another part of the sky. However, if I then try to clone my newly created cloud to another patch of sky, all I get is blank sky … it’s almost as if the cloud, which I can plainly see, is invisible to the retouch tool.
I think each cloning operation (within an instance of the retouch module) starts from the image as it is just before the module. So while you will see the just cloned cloud, a second cloning operation within that instance won’t see it.
So, is there a way of ‘banking’ what you’ve done so far, so that it sees all the changes to date? … or do you have to keep exporting/re-importing?
Thats intended since darktable is nondestructive. You’re also able to revert everything you did while editing independently from other editing steps
In your particular case, a new instance of the retouch module should see the changes from the previous instance. The case you describe is a bit particular, as you want to use the results of an operation within the same module instance (if I understand correctly what you are trying to do).
It’s one of those things that can be reasoned both ways. I think I prefer the current situation, where each cloning operation starts from the original module input.
(And note that that’s the module input, not the original image you started with, so all previous modules are active at that point).
But given your replies so far, perhaps you could describe what you are trying to do, or provide an image you are trying to edit? E.g. you don’t have to create a new module instance for every cloning operation, just when you feel the screen gets too cluttered. But that begs the question why you need that many cloning operations. (20-30 is a lot, I think)
If you hold down the ctrl-key when you choose the retouch tool to use (circle, brush etc) then you won’t see the source/target pairs, and you can also make multiple edits in one go. If you don’t hold ctrl-key, then you will see them and you will also have to choose the tool again for every edit. I have had up to more than 300 retouch edits in one image without problems (dust removal on old negatives). There is no need for new instances of the module until you reach the max number of edits possible. I have reached the limit a couple of times, I think it was around 360 or so. Usually nothing to worry about.
I was just playing generally, trying to get my head around how it all works. 20-30 is not very much when you’re cleaning up old images with lots of dust and other imperfections. Many of my pre-digital pictures, scanned from negatives, have an awful lot of cleaning up to do.
Actually, hpbirkeland’s ctrl-key solution has also solved the problem with the tool not seeing previous clones. I now can clone a clone or even a clone of a cloned clone!
Yes, that worked! I appreciate your help. Thank you.

Yes, I appreciate that, although there are times you want to save a certain level of edits, for fear of messing it up again.
Then you might export and reimport the image as openexr & rec2020 just after retouch …
Maybe save a temporary preset or work with duplicates…just duplicate and continue and go back and delete the duplicates…or insert a dummy no-op module then go back to your retouch …if you screw up you can just go back to where it was in the history. So currently you are on line 10…add an exposure module with no changes. then go back to retouch…if you edit gets messed you can just go back to line 10 and press on…I think that should work…unless you compress it by accident when you screw up and then you would likely lose it if you were not careful but you try to see if you can use something like one of those as you work?? Just a thought
Are you sure you understand what a new instance means? I just cannot imagine that for Retouch it’d work differently from everything else.

DSC_0097.NEF (26.5 MB) Just when I thought I was getting my head around this program, I thought I would download a random image from the internet … just to experiment with. I’ve attached it here. Nothing I learnt about the retouch module (I haven’t tried anything else yet) works with it.
I’m wondering if, maybe, this program might not be what I’m looking for. I’m actually trying to find a suitable replacement for Aperture. My wife uses that all the time and can’t manage without it. Apple have pulled the plug on it so she’s been forced to reset her iMac to an earlier operating system that will allow the program to run. No other program we’ve found offers the features that Aperture has. It’s been suggested that LightRoom is the answer but that doesn’t make financial sense for the modest amount of use it would get. Hence the reason I decided to investigate DarkTable.
I’m a visual learner. Reading through manuals just doesn’t “stick” for me. My wife is even worse. I have to learn a program first then walk her through it. I haven’t found a tutorial video that really explains Darktable 3.4. Those that there are tend to concentrate on the changes from the earlier versions, so expect you to already have prior experience.
if you havn’t found tutorial videos then you havn’t searched for them:

Hi,
while I would recommend the quite extensive series of excellent video tutorials done by Bruce Williams (https://www.youtube.com/channel/UCkqe4BYsllmcxo2dsF-rFQw ) one might face the truth, that darktable might not be the tool for everyone.
Especially when coming from Aperture, one really might get overwhelmed with the technical depth of this program. darktable has quite a learing curve, but for me is well worth the efforts.
If looking at a raw-converter with more easy consumption, you might want to take a look at ART:
agriggio / ART / wiki / Home — Bitbucket
Perhaps this is something better fitting your needs than darktable?
Yes, I’ve been watching Bruce Williams. Yes, he’s very good, but his beginner videos are showing an earlier version. He’s done some videos on the new version, but they assume prior knowledge.
Regarding ART. The Mac versions are only being tested at the moment and I also couldn’t find much about it online, suggesting video resources are limited.
Have you seen his video episodes 84, 85 and 86? They are a three part series specifically for newbees re. darktable 3.4

you can search for the subject in reverse chronological order. If there’s no new video on a topic even older videos are quite valid.

No … I’ll check them out. Thanks.
