thanks, but i believe this is a bit out of my "pay grade" ("knowledge level" to be precise :-) ). Any link (to a tutorial or so) that explains what you are talking about in more detail...? Thank you :-)!
For the RGB to LAB conversion,look up LAB + Program you use. I use each channel data and copy that into Layers. Copy the contents of the LAB channels into Layers and lay them ontop of each other. Disclaimer; this is more of an averaging of the Shadow and Light information within the A and B channels. With additional HSL…
What Pior wrote + some other tips; * get out of the RGB mode. LAB works better in canceling out light information. * you want a specular matte to erase that from the rest. To do that, you want to split the AOpponent and BOpponent from the Lightness (Lightmap). * use Layer filters (Multiply, Linear Light, color etc.) to…
Well, that's simply how Shadows/Highlights operates - basically working as an edge detection filter, similarly to Unsharp Mask. Instead you need to use methods affecting all pixels the same : Levels, Brightness/Contrast, Curves, and so on.

Im doing the diffuse texture in Agisoft Metashape from the original photos that were used for point cloud, mesh etc. generation ( i dont use another…
Ah, thanks... So i stand corrected, Shadows and Highlights do NOT affect the whole image equally... I did not know that :-)... And i used this method for majority of my few hundred scans lol :-)... Only rarely i noticed any seam problems... ehm... :-) was lucky probably Also - Do i understand it correct, that the proper…
