I saw a brilliant thread talking about why the colour red is noisy in post:
I found this incredibly helpful in understanding why red appears that way. What I want to know is what can you do when filming dark red to avoid high levels of noise?
I was recently filming a museum installation and all the walls were dark red brick. This museum was inside so the natural light was very limited, so naturally I shot at my highest aperture (at the time was 3.5) and set my ISO as low as possible. My camera hasn't got the best sensor but I just wondered if there was an explanation or other tips as to what to do when you know you're in a location with lots of dark red.
