If you look carefully on teh Kodak Motion picture film site, there are the formulas for Plus-X _REVERSAL_ and Tri-X _REVERSAL_ which were and are respectively only sold in 16mm. Those formulas are what Movie labs use successfully to reverse ORWO UN54.


The Kodak Movie formulas Don't work reliably with Foma R-100. The Kodak process is more environmentally friendly, and so less effective at bleaching.
