Question about skin tones and Vectorscope reading

April 7, 2018 at 2:29 amhere’s an example of 5 point white balancing. the shirt and coat both reflect blue onto the white. you could make it more perfect with a secondary, but I thought this would be a good example illustrating why local colors can affect overall white balance if your not careful. Also, try eye dropping the beard directly, the whole image will completely go orange.

April 7, 2018 at 4:11 amOn my monitor, your example has a greenish tint to it. The skin tone is good but everything else veers towards green. And looking at the example I put up, it looks nowhere near as good as what I have been getting. I don’t know why it’s tinted towards blue that much.

April 7, 2018 at 4:07 pmThere used to be a term “best light” which was a dailies-workflow designed to try to please dP’s and still fit within a producer’s budget and the post-house’s need to achieve a shred of mark-up on services. Basically, a step up from a “one-light” (which was totally up for abuse in interpretation) and a “matched” set of dailies. But the transfer operator was only allowed RGB primary correction so as not to “hoop” the finishing colorist. The best advice I ever got was “just lay it over the origin.” If you know how to read a vectorscope, you will know what that means.
Colorists did not have access to “histograms” until the first software/commodity-platform-based grading applications were introduced. Never knew what to do with them until the issue was discussed with a LUT developer… the takeaway at least for me was, hmmm… not really all that helpful.
Anyway here is my take… primaries only, no secondaries or curves:Neutral_warm.jpg

If this is the right uploaded image…. if you scrub over the beard, it still seems to have tint — eventually you also have to overcome the perceptual difference with simultaneous dynamic contrast/ complementary contrast.

April 8, 2018 at 2:51 amEven though this is a Samsung 4K HDTV, it’s a bitch to calibrate. The built in Windows calibration doesn’t work. When I try to fix the gamma so that the black circle disappears, it never does, not even close. Same with contrast and brightness. I can not get it to the recommended sample shots. So…. I’ll give your test pattern a try. In the mean time here is an uncorrected straight out of the camera V Log version of the still you guys have had so much fun playing with. Maybe it will be easier for you to tweak.

Here’s a .png version, if this forum allows 6 gig files

April 8, 2018 at 3:06 amHave you calibrated your Tv’s controls as well? If your Tv isn’t partially calibrated, windows can’t do anything about it.
I forgot to tell you, there’s also a Disney Wow disk that will calibrate your Tv so that bluray looks good. -

April 8, 2018 at 3:26 amYes, that’s the part for adjusting contrast and brightness, the tv controls. I can’t get it to match the “ideal” settings no matter to which extreme I adjust them.
I know about Disney Wow. Come on Chris, you know I’m just a kid ???? Remember, my only question was whether my vectorscope has to be on the skin line if my skin tones are good. Anyway, have fun playing with the uncorrected V Log still. I’m curious to see what it will look like on my screen.
