Dear Platypus,
you’re right… the only data I have at the end is the standard files I joined one with this post. This is the final product, but they also did it on each of the nine sections of the photo. This is what I generally performed with the trial and error method, but certification is not free in this case… This is why I asked if someone has already think on that specific point.
Anyway thank you for you help.
Regards
