Re: filmscanners: Yellow barcode, color dashes

[Arthur Entlich <artistic@ampsc.com>]

The markings in the borders of film are exposed during the manufacturing 
process, and they are pretty consistent when they leave the factory 
although they would vary based upon how the emulsion batch responds.

The problem is that they don't stay that way. Besides mild alterations 
due to film handling (age, heat, etc) more importantly, they are just as 
varied by film processing as is the rest of the film image itself.  In 
fact, they can be used to determine if the film received out of spec 
processing.
