Thanks to Alex MacLean for giving me the idea to expose within video mode and switch over to film when I was ready to record.
Thanks to Ryan E. Walters for suggesting the Luxi light meter as well as helping me with this exposure issue. Ryan has a ton of great exposure articles on his site and he also told me about this really good article about exposing within Log mode.
I got an answer from Blackmagic on my exposure question:
The question I am referring to is while shooting do you expose for 18% grey within the frame at 50% on Davinci’s waveform scope while in “film” mode or something lower like 40% or even as low like 32% as Canon publishes in their white papers for their log mode?
Dave:Actually, I do have an answer there. I have been told that 18% at 50 IRE is the way to go, it will give you the latitude needed during grading with us.
