Hello Olivier,
I believe that these were still scanned with Epson 2450 photo. The software is Vuescan which I still use with my current scanner. At the moment I am using the Epson 4990 photo for film scanning. Mostly standard settings used on the 2450. No further post-processing done. I still have the 2450, but am not using it anyome.
Hope this helps.
Take care,
Marinus
