Hi everyone,
As I wrote many times, I'm a self-taught newbie, and I "use" forums to clarify my messy ideas. So, sorry for my basic a chaotic quesions, but I think that probably other guys could be in my condition and could find useful clarifying this topic:
Since I'm an happy user of Magic Lantern's RAW video, I'd like to understand better the concepts of wide gamut and HDR footage. What I hope to have understood is that HDR refers to light, while gamut refers to color: two different things, but I'm interested into how they are related.
Now, my camera (5D3) is set on AdobeRGB, and I shoot videos in RAW. I've read (in this forum) that RAW footage captures more infos even than AdobeRGB, so it should mean that RAW footage has yet wide gamut (perhaps not Rec.2020, but it should be at least as wide as DCI-P3 or even more). So, simply shooting in RAW should let me work in wide gamut workflow. (Right?)
Now, in order to obtain a wider dynamic range, Magic Lantern offers at least 3 tools: HDR, DualISO, and Auto ETTR. More or less, I should have understood that HDR is a tripled-frame capturing to obtain high dynamic frames to both raise shadows and prevent highlights clipping at the same time (right?), while DualISO should do the same thing but this time through a dual-frame capturing and reducing vertical definition (right?), while Auto ETTR should maintain the "distance" between shadows and highlights, raising the shadows and clipping a bit the highlights that are still recoverable thanks to Davinci "recover highlights" button (right?)
Now, these three methods are different, but it seems to me they are oriented to a similar purpose: obtaining the widest dynamic range.
What I hope to have understood is that both HDR RAW and non-HDR RAW videos are good for wide gamut workflow. (right?)
Now, can we consider DCI-P3 a wide gamut color space? I'm interested into this because I'm going to try coloring a video work for a theatrical premiere. Anyway, to handle a DCI-P3 10bit work, I should have a 10bit P3 compatible monitor: for example Eizo CG2730 declares true 10bit and 98% P3. But if I want to use Eizo as preview monitor, and work at 10bit, I have to use a PCI Decklink Mini Monitor, and this brings me to a problem: Decklink can handle only Rec.709 color space. So my question is: how can I take advantage of Eizo's many profiles if Decklink can handle only Rec.709? The same thing for AdobeRGB: my camera is set to AdobeRGB, and Eizo can handle it at 99%, but again Decklink can't handle it, so if I would like to have a correct preview of my footage in its native color space, what should I do? (A Quadro card? I'd hope there is a much more cheap solution... because it should mean using my Titan X fog GUI monitoring, and a Quadro for preview monitoring? Possible something cheaper?)
Thanks a lot.
