I assume that the only remaining industrial lab in Austria now uses Fuji chemistry.
My Velvias from the early 1990s, ISO 100 push developed by Kodak in Vienna, all came back too dark, too contrasty and too warm, with these ill-famed orange flesh tones. This was the main reason that I quit shooting especially this film, remaining very skeptical about the praises.
I recently bought two new Velvia 50 rolls and used one for a test shooting at a sunny autumn day, again pushed one f-stop. The results pleased me, with a good highlight/shadow latitude, the juicy reds, blues and greens, a slightly lighter maximum density improving scanning, and a quite natural skin color (at least for average Austrians). It appears that the lab prefers Fuji-Hunt chemistry for a good reason. Fortunately I can thus stay with the nominal speed.
With the dedicated coloraid IT8.7 target offered by Wolf Faust, calibration for Velvia improves scanning color fidelity; there is still no such tool for Ektachrome 100VS/EBX to obtain neutral and correct results, neither by Kodak nor by independent manufacturers.
Congratulations, Fuji!
