Interestingly, Foma adds antihalation to its 120 and large format films (the developer turns a very bright green), but not to its 35mm films (no color change in the developer). This is confirmed by their data sheets.
Mmm...
But i have one portrait done in Foma 400, 120 format where i can clearly see the halation on the (very bright) highlights.
The datasheet says that the 120 version is "furnished with an antihalo colour backing which will decolourize during processing."
This does not mean the 35mm has no anti-halation measures built in.
And all of this does not mean the film has a very strong resilience to halation (compared to a film like Delta 100).
And at the same time it does have a better anti-halation strength than for example Shanghai GP3 !!
