The nice thing about Anscochrome is while it fades it does not do the kind of color shift that is so typical of Ektachrome from the same era.
All the Anscochrome takes is some correction of contrast and saturation and it pops right back....and can look just about as good as the old Kodachromes (except the Anscochrome has much more grain). The old color shifted (to orange) Ektachromes are very difficult to fix...I have a bunch I have been working on for some time and still not happy with the result.
