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?


Best
