My first thought would be to check the scanning process. What scanner was used and was it "set" for a "Color Negative" source?
Offhand, the so-called "orange mask" common to mst CN films appears to have been reproduced faithfully. If this is NOT the case... I would suspect ... "fried film", far, FAR beyond the "expiration date", or in some way stored in a very hostile (read: glove compartment through a New Mexican summer) enviroment.
I'm curious about what did happen.
