Color labs are the main problem of me going to digital for color.
A lab in For "Agfa" in South Africa, had to send control strips daily to Leverkusen Germany for quality control.
Sadly the lab person, did all strips on day chemicals first prepared!
Stored in freezer and released on a "daily" basis..
All Agfa prints in ZA faded..short changed there by Agfa not using same method as Kodak....
I had a foot-print (partial) on Ektacrome done at another lab.
Kodak had a power failure with my films in process ruining 9 rolls!
They would only agree to replace 2 rolls..
I have heaps of 120 and 35mm color film, now outdated..
