I actually think (read bias into it if you like, but I'm serious) that the still of my LUT applied to your image looks much nicer than the Neumann one. Your graded V-Log one looks more like mine from the thumbnail, but please do show us the full size ones for comparison, as I would especially like to lift the black levels on mine to show you the same look as the Neumann LUT
As always, I appreciate criticism too! That's how we improve

By the way, I find ISO 400 to show the most dynamic range with my LUT too, so that's something to consider.

Leeming Lut lifted shadow to match VLOG
VLOG Nuemann Lut.
Look at the color channels.
Not the same.
The only thing I see in your LUT is an improvement to the color of the blue channel for CineD for things like skies. Your greens however are super fluorescent looking.
Enjoy your $15.

Dynamic range is NOT highlight retention. Digital sensors either have highlight info, or they are clipped. "Rolloff" is more a function of where middle grey sits relative to how many stops above that still hold information clipping.
Dynamic range is: Set the exposure to JUST beneath clipping range at the highlight end (99.9% if you will). Now look down into the shadows. How far down can you see usable information? This is what I refer to by dynamic range. If you compare V-Log L and Cinelike D with -5 -3 -5 0 0 (forget my LUT portion, the original uncorrected file will do) you will see that if both are properly exposed to hit 99.9% of highlight value, you'll be able to match the levels between them and find the same amount of shadow detail visible. This is what I refer to when I say they have the same dynamic range. The difference is, V-Log L gives a bunch of extra noise and colour smearing that Cinelike D doesn't, hence you can extract a cleaner shadow level from Cinelike D if you match levels.
If I had one I'd shoot a Stouffer chart, then there would be no more discussion. Unfortunately I don't have one. If anyone has one, please let me know. I'll throw a freebie your way in order to get a definitive answer.

It's weird. I'm not seeing hard noise floors like you are. If I lift shadows in dark shots, they roll upwards like your V-Log example.
Original Cinelike D direct out of camera (underexposed - this was a torture test clip):
Leeming LUT One applied only, no further adjustments (image is actually made darker, due to correcting for tonality):
LUT applied and shadows/blacks lifted. Note there is information there, not a flat line:
Hopefully someone else can chime in with their own tests as well. I truly want this to be the best LUT that's non V-Log oriented, so it's good to get critical feedback to make it even better
Can you post the Cinelike D clip without my LUT applied and shadows lifted, to see if it makes a difference?

You're recording internally, right? Just checking to be sure.
Would also really love some 4K uncompressed PNG files to pixel peep on your stills. Because in my experience there's no way to avoid the magenta unless you're recording external 10 bit.
