Colour shift and condition I do believe are legitimately, two separate issues regarding film.
Colour shift (if applicable) should be described separately to condition as they are two completely separate things imo.
There is little anyone can do to avoid colour shift on a print, especially when on Eastman etc.
A set of screenshots provides me personally with all I need to know surrounding this issue.
A print in my opinion can feasibly be described as in excellent condition while still containing SOME fade, so long as it isn't completely red and as long as all below is above and beyond the norm with these things.
Condition should describe such things as scratches, neg marks, print blotches, quality of the negative used for printing it, therefore grain and sharpness etc etc.
As well as this, film stock preferably should be mentioned where it can be identified and also importantly, quality of stripe, type of stripe, quality of soundtrack on either the main or balance stripe or both where applicable.
If I have all this information to hand when deciding upon a purchase, plus the proof by accompanying screenshots etc, then I'm happy.
Seldom am I entirely happy with people's descriptions regarding films offered up for sale.
Even less so for the very expensive ones ironically!
If sellers have nothing to hide, why not give a detailed accurate description of their films offered for sale?
Anyone who regularly and reliably does,.. instantly sees the benefits of doing so by the prices reached and the shear amount of interest generated by their goods.
What I have found bizarrely over the years, is there are plenty of people trying to sell films that want "A" grade prices for "C or D" grade prints.
Why these characters should expect this to be acceptable behaviour is quite frankly, utterly beyond my comprehension.
