Many thanks for you help David!!!
Getting close to the shooting, our concept has been clearing up; We definitely find 'Singing in the rain' as the best visual refference. To me it seems that no other stocks can deliver that partical look, but reversal film and even though there is no chance for a test, think I just have to go for it and rely on my research...
You are right, studying the lighting of 'Singing in the rain' I learnt that they were using hard frontal sources and also hard backlights and the scenes have an evenly lit feel, without much separation of foreground-background (assume reversal stock would not allow for more lattitude.)
However, we will have two-people romantic macro scenes in a studio in front of 10x10 canvas backdroups (kitchy sunset, cloudy sky, city landscap etc).
My biggest concern is now applying the appropiate hard lighting style without having the shadows on the backdrop. (Since the couple has to be pretty close to it on full shots without falling out of the set.) Especially shooting on 7285, with 25TASA.
I thought of lighting fontal from above, filling from under (avoiding the thrown of shadows to the backdrop) and using very hard backlights. I would have expose for the evenly lit couples in the foreground and I would light the canvas also evenly from the side and keeping it 1 and a half, two stop under compared to the foreground.
Your feedback on this concept would be more that greatly appreciated.
Thanks again,
Mate
