Oh no don't worry its a 400' roll! I'd worrying if it was only 100! The reason we only get one roll is that it is for the Kodak Student Commercial competition and thats the rules.
I had thought about shooting it all unfiltered. But as I would be the one grading it and I am not too sure about my grading skills just yet so much as to trust the whole look to that. I prefer to get it as much in camera as possible. I will be shooting mostly natural light, atleast in the car and countryside, there will be lighting setups in the apartment.
I have been thinking though that shooting uncorrected tungsten in daylight for the apartment scenes, although set in very early morning, will be too blue for what I am looking for. Maybe if I shoot that scene with the 81ef then move on to another filter for the car scenes, what is there in between the 81ef and 85 that would give me a still slightly cold look?
