I'm prepping for a black and white feature at the moment that I'll be shooting on the Alexa Studio. Tested out some standard B+W Contrast Filters yesterday to see how they'd play on a digital sensor (I haven't used them since my darkroom days), and found the effect sort of worked, but certainly seemed to leave me with less capacity to push the image around than shooting clean and fiddling with my RGB channels.
So I'm leaning towards simply shooting clean now, and jacking my RGB channels around to create a really graphic look.
I was wondering if anyone had any 'best-practice' recommendations for this approach?
We don't mind gaining a bit of noise from messing the image up, but we're only recording ProRes4444 for this one, so I'm wondering about whether I should look into rating the camera around 200-320 ISO to keep things as noiseless as possible, to facilitate pushing the channels (particularly red) all the way up with as little adverse noise as possible?
Any thoughts or suggestions would be greatly appreciated.
