Is it only me or comparing with the Action 4 with same settings the Action 5 DLogM shows more magenta in skin tones?
I could expect in Normal color profile but wondering why DLogM should be affected by modern trends.
Nearly all shots i need to desaturate magenta to avoid looking as i've been burnt by prolonged sun exposure.

Sure thing. I attach the picture here. Left is Action 5, right is Action 4. I noticed a tendence of Action 5 to shift to magenta way more than Action 4 does. Maybe this is a marketing choice because more magenta is maybe more appealing than more green, don't know. That said, the 5 from time to time falls into exaggeration and a desaturation is needed to fix the footage. Please notice that all the rest is balanced more or less the same way, and the camera are set with same settings (in this case auto WB but please notice that the wall is balanced nearly the same while on the right is a bit more cold)

Hi there. Sorry for the inconvenience. Could you please send us the original materials of AC4 and AC5? Engineers need original material for comparison. Thank you for your understanding and cooperation.

Will give it a try soon. I expected they fixed the internal colour science rather than publishing a correcting LUT but that's it.

I probably posted this a bit too quickly yesterday. I've tried it out now and these are not LUTs to convert the basic material but rather LUTs to display other effects such as spring, autumn, summer, winter. They are quite useful in themselves but not a normal color correction to rec. 709. Rather from rec. 709 to another optic.

Got it. Quite useful anyway. Have to dig into.

I think i have seen this not even only on human skin. Check this example the saturation of the bus color is insane on the right

It's difficult to decide if the BUS saturation is weird as we don't have a comparison. I may say that it's ok, given that the man skin on the right looks normal. It's easier to spot wrong colors on skin just because one usually know how the skin looks.
