Question

Well almost the same.The pickup in the first half of this video is VERY red and the pickup in the second half is VERY orange,but as you can see they're almost the same colour.I don't remember them being like this before (but can't find any earlier examples).As you can see all other colours show near as [ ] perfectly.

Is there an easy way to get reds to be red again and oranges to be orange again as I don't know the correct way to do it with something like Adobe Premiere Pro?

    They look very different colors to me.

    What are the two comparisons from? In detail, please ... as without a lot more information, there's no way to do anything but wild guessing.

    The first one is not the same pickup in the video but is the same shade of red.The second one is the same orange pickup in the video and is the only still photo I have of it,but in real life it's a deeper orange than that.

    "The truck on the left in your capture is shiny dark red (sort of burgundy),the one on the right is bright and shiny red"

    are you saying that's what you see in my picture or what its supposed to be?

    because I see one burgundy and one orange. like I said, you can use secondaries to fix the colors.

    Unless you heavily tweaked the hues in your camera before they got recorded to the memory card, I believe

    that reds might be a limitation of that camera. the only way to know for sure is to use a professional color chart

    then create with a 3d lut generator. that camera might have a crazy color gamut like srgb offset somewhere.


    Big problem is OP is on auto-WB. Says he gets a bit of his hand, then gray card, then shoots the cars. Then wants to know how to sample his hand or  gray-card, and apply that to the cars scene.

    That's not how auto-WB works of course, as it's like auto-exposure, shifting constantly due to the colors seen. So ... knowing how this works, his recorded colors with those intense cars being such a large part of the scene are really going to be off, and as it will dramatically shift color response for every car, there's no place to standardize. It is doubtful he has the data to properly recover. And the setup shot with his hand & gray card is utterly useless.

    Until he gets off auto-WB in the camera, he's got a significant problem.
