D Log M (with Auto ISO) Superior to D Log

[AKA_Goodfella]

I recently upgraded from my Mavic 3 pro to the Mavic 4 Pro.

One of the main reasons was to have finally D Log on all 3 lenses. This would mean so much easier grading all 3 lenses in post.

It seems however that D LOG M (with Auto ISO) is superior to regular D LOG in terms of Dynamic Range, testing have been done by Gerald Undone, its even better then the new ProRES competitor ALL I. I was really surprised by all this.

auto iso will give you nightmares in post, stick to manual everything. d log m adds compression to highlights and expands shadows so has the potential to produce a better finished job, but from personal experience, working with log in post is not easy. It takes quite a lot of skill, experience and practice. Also I wouldn’t depend on LUTs to do the grading and colour correction, they can be damaging. Great video. Edit - the video is dated April, subsequent reviews have said the M4P uses quad bayer sensor DJI Mavic 4 Pro Review – 100 Megapixels Just a Big Number?

I'm going to attach a link at the end (current end) of this thread for you to check out. You may end up reevaluating your statement that LUT's can be damaging.

I'd suggest everyone look at this video for a different perspective.

While I haven't had a chance to test yet (my M4P is still stuck in customs going on a month now with no signs of it being released) it sounds like D Log M is the only way to enable dual ISO. Someone correct me if I'm wrong though as I would like to understand this better but if that's the case I would use this mode in low light situations.

Does the fact that the M4P is a quad Bayer sensor in any way invalidate their findings that Auto ISO or Autoexposure in D Log M produces superior results over D Log? Anything flawed in their testing methodology that would invalidate their conclusions?

They also provide a link to DJI's free LUT for D Log M, and their original files upon which they based their conclusions, so one can evaluate the differences oneself.

Do you now still disagree with their findings?
