Wouldn’t it be loverly if WYSIWYG?
Resolve pretty much operates in Rec709 by default, unless you deliberately go away from it by slipping a LUT in the mattebox. Internal computer graphics previews are operating in sRGB, which is similar, but not exactly the same as 709. That is where external SDI Video I/O interfaces like Decklink come in — and there are emulation modes included in many grade monitors that allow you to see your values as mapped to various colorspaces. That is the one big real advantage over graphics displays, plus of course accuracy and reliability.
Linearizing your dpx files in Resolve really is asking for the value scaling — 0-1023 or 64-940?
As far as gamma characteristic goes, depending on whether the dpx files were digitized log or not, I would be surprised if anyone went to the extent of customizing an antilog for a specific stock — that would have to be tweaked for every batch. Its a bit like the so-called film log curves that some digital cameras provide — they’re not log at all, but simply flattened out to try to avoid clip/crushing the high-and low-lights, and its “up to you” to eye-ball it out, and usually, with a scope, its not a challenge, and a hand-built S-curve is the most efficient path for that. Ultimately, make it look good – that’s what we do.
And as the manual and various tutorials point out, the “log” controls in DaVinci primaries aren’t specifically for reverse log operations — they’re just a remapping of the overall controls that are pinned at different control points, which you can slide around (pivot).
