I'm currently shooting with the Scarlet and have been running into blue specks of noise in the shadows. After reading around I've come to the conclusion that I am obviously "under-exposing" the shadows. My question is, why does that create noise? Isn't the point of a shadow that it is under-exposed and darker than your subject? How do you film someone against a background that is supposed to be in shadow without getting this blue noise?
1/96 sec shutter
1:7 compression ratio
Zeiss Super speed glass (typical stops ranging from 1.2-4.5)
You'll notice in the R3D snapshot I've here: http://www.mediafire.com/file/iwqhq2...1.0000320F.R3D
That the blacks on this particular shot are very concentrated with a specifically "blue" noise. How do I shoot a shot like this without getting that (and without having to crush the blacks in post)?
