'Sure Be Nice If Ektachrome Wasn't the Only One Available...

[paddycook]

The inherent problems in the last versions of Kodachrome - which were a bit better than earlier versions - meant that there was a built in inability to achieve colour fidelity.
The E6 films of the same era did not suffer from those problems, and were therefore able to achieve better colour fidelity.
I guess you could design into modern E6 materials the problems with Kodachrome colour fidelity, but would you want to?

What “inherent problems”? Kodachrome (especially Kodachrome 25) always reproduced the scene much more faithfully than Ektachrome in my experience.

The classic early E-6 Ektachrome 64 suffered from red contamination of the greens. That could produce wonderful renderings of sage and muted bluish off-green hues, but couldn't hit the nail on the head with cleaner spring greens, that is, unless a special masking correction was applied to dye transfer printing. But as soon as Fujichrome 50 came out, it was the other way around. Alas, no one film does it all. As far as Kodachrome goes, I much preferred the 25 version to the subsequent 64; but other than experimenting briefly with 120 Kodachrome, I was shifting entirely to 4x5 at the time anyway. Just in time for the advent of Cibachrome, first version.
