DJI Mavic 2 D-Log M for Color Space Transform?

Hi there,

I got myself a Mavic 2 Pro and it can record in D-Log M. DJI provides a LUT for D-Log M to Rec709 but I recently learned of the color space transform plugin which I wanted to use in the future for converting color spaces etc. and I was quite happy to find DJI D-Gamut for Input Color Space and DJI D-log for Input Gamma. But those two options do not give the same result as DJIs Lut.

So I do believe the D-Log M to be a bit different to D-Log. Would it be possible to include this new LOG Version into the color space transform plugin?

if you have the white paper it is possible to build a DCTL that mathematically transform to a known color space (like LogC)

here. the gamut is similar to film log.

Okay, that sounds like a reasonable idea, although I have no idea how to do it. Might just have to teach myself about DCTL. But thank you for the time to look up that paper!

Also, one of the color science in our facilities suggested that being close enough to arri logc you can flag it as such and color the difference.

I've looked a bit further into this.

The whitepaper you found is for the D-Log Gamut but the Mavic 2 uses a similar but different Gammut called D-Log M.

So far there has only been a LUT to convert to Rec.709 that has been released by DJI but no whitepaper (https://forum.dji.com/thread-163592-2-1.html).

Just for further reference if someone stumbles upon this.

Look up Paul Dore's thread on this; members have provided conversions for testing.
