I'm a total beginner with Gimp and am completely stumped. I combined two images by layering one over the other. I zoomed in to one layer and touched up some details with the clone tool. When I zoomed back out, the whole image (both layers) is covered in black dots. An example of what I mean by "black dots" is attached. Why did this happen? I can't figure out how to undo it so I want to avoid doing it again. Any insight would be appreciated.
More information needed. It reads like you are cloning from one layer to another. Do you have the clone tool in registered mode?
Then that does use a brush, so the brush shape and all the properties come into effect. Make sure of opacity / size / Dynamics / modes
Possibly your problem lies if you moved one of the layers and it is now offset. Clone (registered mode) will take into account any offset so what is directly under is not cloned in the over layer.
I did offset one layer from the other, now that you mention it. I don't know whether the clone tool was in Registered Mode, it was in whatever mode is default. Attached is a full screenshot. Thanks for looking.
That is a big image and in 32 bit FP mode, which should not be a problem. Good choice for a brush - the 50 fuzzy one but the size shown is tiny - only 3 pix - very small for such a large image.
The remainder of the clone tool options are not showing so here is a short, 4 minute demo, of the various options. https://youtu.be/gP5ogpd2RYo
You might see something in that relevant to your image. The offset layer can be set to canvas size using Layer -> Layer to Image Size That might help.
Thank you for taking the time to make that video. I had been using a 3 px brush to zoom way in and remove some cat hairs from the image. The reason for the large image size and attention to minor details like that is that, if I can get things working right, this will become a 2000 piece jigsaw puzzle. Things I tried:
- removing the offset between layers
- toggling the visibility of the background layer
- deleting the background image
- setting the clone tool's alignment option to Registered
None of these got rid of the black dots. Is there a way to retroactively apply the setting Registered to parts I've already modified with Clone?
Again, thanks for taking the time to help a total newbie.
You will not get rid of the black dots if you saved the image and came back to it. Any undo is on a session-only basis and is lost after a save.
The only way now is start again. I have to confess, I still do not know why you got a smattering of black across both images. Probably nothing to do with the clone tool.
When I originally cut out my daughter (girl in the rainbow dress) I used the fuzzy select tool. It did a pretty good job of finding her edges, but it also selected a few stray pixels and small patches on her dress. I deselected as many of those as I could, but didn't get all of them. Could that have had something to do with it? This time I used the scissors select which worked much better.

Another useful way to select is paint-in the selection. Gimp has a tool quick-mask see: https://docs.gimp.org/2.10/en/gimp-image...utton.html Either paint in the whole selection or add / subtract from a selection made by another tool.
