digital cameras use sensors with many pixels - millions of these are standard nowadays. I suggest to develop a workflow which could correct many of these visual defects (more ot less) automatically. Reproducible: Always Steps to Reproduce: 1. dead pixels or dust may appear without announcement (suddenly) on a picture 2. theses/concept idea: if comparing two pictures, there must be a situation, where the first one is still ok, and the subsequent picture is affected (dust on a lense, e.g.) 3. Actual Results: digiKam does not take care of such picture defects. Expected Results: digiKam should (could?) automatically repair such mistakes. Which defects I am thinking of? - dead pixels (https://en.wikipedia.org/wiki/Defective_pixel) - dust on a lens, filter, etc. All these defects appear on the pic later. They appear on all pictures from a certain begin on. Tools for picture repair under. http://restoreinpaint.sourceforge.net/links.htm or http://sourceforge.net/projects/imageinpainting/files/ A reasonable strategy could be to compare pictures pairwise, to extract "common picture information" which would be the difference of two pics containing the fault, I want to differentiate out.
In Editor, menu Enhance/Hot Pixels tool is dedicated to this job... Look here and search string "Hot Pixels Correction" http://docs.kde.org/development/en/extragear-graphics/digikam/photographic-editing.html#editor-correct-tools Best Gilles Caulier
Dear Gilles: Great link (...docs.kde.org...) for hot pixels.. wondering, why I didn't know about before...? I was suggesting a tool not only for "hot piels", but also for "hot dust". Do not rely know, how to deal with that, but some links could indicate a way for (impainting,...) My intention is a tool, which can _automatically_ "repair" (to some degree). Besides of "hot pixels", for which you taking care already, I suggest to extent this "conditioning tool" to erase (="repair") the traces of dust on the front lens (front filter). I take this not only for next generation tool, as I am affected by dust a lot in landscape fotography. I believe, this could help to erase this type of defects in background, maybe before or even before loading the picfor further eloborations. You know, what I mean? Sometimes, you catch dust on a sensor or front lense. But you don't notice that- until you are at home and you think about cleaning our equipment.... this chance for the pic has gone, the defective pictures remain in your collecton! Howto find out these pics, how to deal with them? Therefore I wrote "from one moment on" (or similar, all subsequent pictures are affected, meaning defective) I suggest to compare continously pairwise / triples/ quadrupels of pics...until you find the dust first time in e series of pictures. From thereon, you easily subtract this "bad infornmtion" from all following pictures... Understand?

Axel, See entry #132483... Gilles Caulier *** This bug has been marked as a duplicate of bug 132483 ***
With 6.3.0, digiKam image editor has a new GmicQt plugin where plenty "Repair" tools are available. Please take a look: https://imgur.com/VSEG86Y With next 6.4.0, editor will also gain a new Clone tool: https://imgur.com/pKn8Ff1 Gilles Caulier

GmicQt digiKam plugin has inpainting functions. Please look my screenshot : https://i.imgur.com/qPvdRoS.png No need to write a new plugin for that... Gilles Caulier
