Moin Klaus!(posted 8966 days ago)Please check if your films are UP 100 or UP 100 PLUS. The Plus-versions seem to be Ilford FP4+ and HP5+. At least I used the 400 Plus like HP5+ and could not figure out a difference.
The older non-plus version seems to be Fomapan 100 and 400. Check the develoment table at digitaltruth.
Kind Regards!
