This recipe is based on the Agfa Vista 400 film. Since X-Trans III doesn't have Classic Neg i tried to get a good look with Classic Chrome based on some images i found online.
Ulltimately i decided to go for a more natural look, so it might not resemble the original film.
If you wish to go for a more vintage (or different) vibe, change one or all of these settings:
Highlights to -1
WB Blue shift to -2 circa
Color to +1
