Does Darktable have spot removal?
The spot removal module benefited from some of the cool features of retouch. For example, it is now possible to set the opacity of the shapes individually (control+scroll).
Is Darktable better than RawTherapee?
RawTherapee edges out Darktable in terms of color correction and the sheer number of edit functions you can perform. It’s a remarkable bit of opensource editing software, but the features can be tough to master because of the less than intuitive interface. Darktable, on the other hand, is well suited for beginners.
How do you undo in Darktable?
Press Ctrl+Z to undo the last modification and Ctrl+Y to redo the last undone modification (if any).
