RE: filmscanners: Film base deterioration (was Digital Shortcomings)


While all films today may not be Estar, they are not acetate from what I
understand - may be Mylar or someother plastic base - but I could be wrong
about that.

It appears to apply to all films on acetate stock. Very few films (sheet
film aside) use an Estar base even now. AFAIK among 35mm/120, only Kodak
HIR & Tech Pan are Estar. Maybe also P3200/TMZ - can't remember offhand.
