@jbinpg: ...You are not far...but ...dcraw is just "converting tool" and not "editing picture tool"
@Eagle_Friends, patriotap: Yes i not understand hou have problems with translation "google"
so , i you response to directly with my bad english, you have not a "translate" langage in line
Or you write this...because you have not the response solution
I give the response (nobody has found)
You give one BIG thank's to him one member here (not me), Only him make this... SENT to me one PEF for try...
WITHOUT him, you have NOT this info, because it's the ONLY MEMBER lost 5mn for sending to me this PEF
The good response is "7" (rawtherapee)
Checked with 100% Succes in PEF mode with k-5
Warning: Rawtherappe is always in BETA mode
