Gamma for most possible DR

[Bryce Lansing]

I shot a film on the RED, and unfortunately we had to shoot a lot of it under light trees with hard sun coming through and I had no lighting or grip equipment. What is the best gamma (or other settings) to use for the best possible DR? I want to keep as much shadow and highlight detail as I can.

RedColor2 and RedLogFilm.

There's no in-camera setting to maximize DR as we record RAW. Check your exposure with the exposure-check false colour mode to ensure you don't clip anything important. Then develop in post with REDLogFilm as the gamma curve to allow you to see the full range for grading.

Ok thanks. If highlights clipped a little, they can be brought down by bringing the ISO down right? Or will that raise other issues?

 

[Bob Gruen]

Clipped is clipped, which means there is no data there...

So everything that showed up yellow in false color was what clipped and I can't get back right? What about what fell between 90-100 ire? I set zebras for 90-100 and there were some spots that had zebras but weren't yellow.

Forget zebras for this issue. Clipping means all three channels saturated (all the traffic lights on for example). Where that happened, you are out of luck, pulling down will only turn pure white into grey.
But if only one channel wasn't clipped, you can regain some detail with DRX.

Don't think video with the RED, think digital film negative.

There's a special raw referenced "exposure check" false colour mode. The image goes black and white, with red indicating clipped highlights and purple shadows that may be noisy if key things to be visible have turned purple.
