Re: [Avid-L2] HDR vs SDR in production?

Yes a wide dynamic cameras output can be made into SDR. The grader just decides how to compress the wide luminance down to 100nits.
Just as an SDR camera would do internally anyway. The advantage of capturing and storing wide dynamic range through to the grade is that the colourist has control over that compression. 
However if your wide dynamic range content is recorded SDR (so in camera processing has been applied) you will get poor results when you try and drag those 100nit highlights to 10 20 or 30 times level.
Detail just isn't there. Like trying to make 3D from 2D content. Yes it can be done but it won't look good. 
So ensure you have a wide dynamic range sensor. Capture raw or use a log LUT. Ensure exposure (iris) is pushed higher than you'd do for SDR content.
