Mr Parker : Velvia pulls quite poorly. In fact, no current chrome films pull well.
I have to disagree here from my experience. Have got good results with pulled Velvia 50 (works better than Velvia 100), and very good results with Provia 100F. And I am not the only one, as photographer friends of mine have the same results.
Polarizers do not decrease contrast.
Of course they can do: E.g. in a landscape secene by turning the pol-filter you get more intense (more blue) and
darker sky in relation to the ground. Depending on the direction of the sun and your wanted result you can often decrease the contrast between the blue sky and the ground by 1-2 stops. I am doing that very often for years with excellent results. And here again, I am definitely not the only one

.
Fill flash doesn't work all that well when the scene is across a canyon,
That is right, but in lots of other scenes it works perfectly, e.g. people in shade in the foreground. That technique has been used for decades in professional fashion photography. And it is still used there, now with digital imaging, because it improves the results.
and grad filters merely make things look cheesy and fake.
Sorry to say, but that sounds arrogant. Gradual filters are very successfully used for decades by countless professional landscape photographers, with film and digital. Used by excellent photographers who are doing their living by selling their pictures. And no, their results don't look cheesy and fake. They know how to use it (and I know, too

).
How much Velvia have you actually printed? You named three half-baked tricks. I know far more. I've shot or used in the lab every Fujichrome sheet film from the inception : Fuji 50D, Tungsten 64, every generation of Provia, all the Velvia series, every generation of Astia and the related CDU duplicating films, as well as all the Kodak E6 counterparts. And I've used most of em in 8X10 format, where the price penalty for choosing the wrong film is rather painful. I've got all kinds of punch and register lab gear to handle contrast the precise way. But there is damn little wiggle room with Velvia regardless.
You are not the only one who has used many colour reversal films. I have, too, I am using them regularly, and probably using more p.a. than most of the users here. I know my stuff. My photographer friends as well.
And incidentally, as far as those easier to load 120 reels, which are nice, that no longer applies to their second generation ACROS II b&w film, which is finished in England and not by Fuji themselves anymore, and uses ordinary Ilford spools. So I save my Fuji ones for at least the take-up end.
I know that of course. But the topic here was Fuji colour reversal film, and both Velvias and Provia have the excellent original Fuji converting as described by me above.
