Hi there,
this is not a in-depth tutorial by any means (since I would consider myself an intermediate noob at AI, and I'm still very fuzzy on the technical details), but merely a very quick tip:
I remove unwanted elements in pictures with a flux-klein-9b inpaint workflow, using the magic prompt words:
remove motion lines, emanata, agitrons, wetness,
Of all those words, I only knew motion lines and wetness (Krea 2 seems to be quite fond of it),
Agitrons are the small squiggly lines that represent shaking ,
Emanata is quite a range of things: invisible forces, paths, smells, emotional states.....
Not sure under which Category to post this, so Musing it is ....
