GH4 LUT

[AaronChicago]

Hey all,

I'm working on a LUT for 3200k and 4600k for Cinelike D on the GH4. I know it's a little late to the game since VLOG is around the corner, but I'm trying to focus on skin tones. Any comments on the skin tone of this shot? Too yellow, too red?

They look good to me! My only gripe is that his shirt is going supernova around the Simpson logo.

To me it looks a touch unnatural. Try this and tell me if you like it better with that correction applied, I kinda do:

With the other channels less correction needed... I made a before/after gif:

​I do like it. Less saturated. I was creating more of a stylized look that is less natural but wanted to maintain a good skintone color. Maybe I'll just bring down the yellow saturation in the midtones.

Tweaked - less yellow/orange saturation in the mids.

​Looks a little chalky/pink to me.

I'm going to test it on a couple of more lighting scenarios and see if i can come up with a nice balance between pink and orange/yellow. It might make sense to go with a bit less saturated a dial it up when needed after the LUT.

No reason you can't make multiple LUTs depending on the look you're going for. One philosophy for grading is to apply 'too much' then dial it back.

​Don't forget to keep some red in there. You need at least a little pure red to keep skin looking natural, not plasticky.

I can't comment, because I suspect you did not embed colourspace info in your JPEG - my wide gamut monitor is not liking the output.

​Native from camera to JPEG. I believe GH4 is sRGB? 0-255.

Hmm, ok, because it's looking a bit like a recent Hollywood film here (teal+orange), which I'm sure it's not what you had in mind. >.>

I would just comment on the shirt, looks either clipped or very near. Maybe lower the gain and raise the gamma. 

Honestly, I would shoot an interview with a 5D/proper white balance, low contrast and color, and try to match that. If you did a side by side, I feel like that would be a great reference. If you're anywhere close to that, then you know you're doing it right.
