Our very own JMK in his otherwise excellent review of Fanny, wrote: "Technicolor by the 1960s just wasn't what it used to be, and this particular film seems to be a bit on the yellow side."
This is the sort of statement that causes so much confusion and misinformation about transfers and color, and it should be amended immediately. IB Technicolor prints in the 1960s were amazingly beautiful. That was how Fanny was printed and it had no yellow/orange bias at all in the IB prints. What you are talking about here is a TRANSFER element problem, not a photography problem. They were given an incorrectly timed element and didn't do anything to help it in the telecine room - it's that simple. It has nothing to do with the great Cardiff original photography or how the original IB prints looked (which Cardiff approved). For years, this was a problem on Cardiff's masterpiece, Black Narcissus - the elements used for various transfers were on the yellow side or even the green side. Everyone incorrectly assumed that that was the way Tech was back then, just because they'd never seen a true IB Tech print of it and because those transfers were otherwise excellent (not the Criterion, which was and is terrible). When the French DVD came out two years ago we finally had a great transfer that actually looked like the film's original look and it was amazing. DVD is never going to replicate exactly, but this French DVD came close.
Point being, take some of that yellow/orange out of the Fanny transfer, and voila, you're much closer to the original look of the IB prints.
