  • Different and the same color at the same time.. helt

    The left image is from Panasonic AF100, and to the right is a color matched BMCC
    theyr skin and hair is the same, the fabrics in the room is way different.. Why?

    Color science and sensors are different for the two cameras. In Resolve, i would try hue curves (and maybe keys if needed) to try get a closer match for the fabric/clothing. Not sure what the equivalent in speedgrade is.

        Sure, but matching may require more work. This is the case for any two different cameras. Its part of a colorists job at times, to match footage from different cameras.
        I would also try the new color match tool in Resolve, and shoot a (compatible) chart with each camera.

          Can my camera be faulty?
          Couse on every shot a do I en up with a hard won battle to make it look natural. Natural like a good set up Sony Eng camera or Panasonic af100...

          I've owned the camera seance October but haven't started shooting until now really, and I cant escape that the colors are awful.
          left panasonic - right bmcc

          I bought the camera cause of the dynamic range, could never dream that I wouldn't be able to get a good shot a Caucasian on it.
          Everything av'e shot is the same thing, distorted colors!

            Not sure what the above statement means, as all skin tones fall within the same parameters no matter what ethnicity. Visioncolor will have a solution for you soon, but probably not soon enough

              Are you shooting ProRes or RAW ?

              Perhaps you could upload your original DNG files for others to try ?

              I'm also wondering if you're seeing some IR contamination on the synthetic fabrics on the first images....

              Are you using a tungsten / Halogen light source there ? Have you got some IR filters you could try ? You might get a nicer result ?

              Some people report getting better results with a higher WB setting even under tungsten. So you could try shooting in proRes at 4500K even when in 3200K lighting.

                Red looks a little hot on the BMCC grade compared to the AF100.
                Under the RGB correction tool in Resolve you might try playing with the individual color bias and gamma settings to get a closer track between the different color matrices.
                My D16 seems to bias hot in the red and blue channel compared to most video cameras.

                  I shot tungsten on prores without IR-filter.

                  the close up is bmcc with resolves film to rec.709v2 lut applied and its very obvious something is wrong. the bottom picture shows how it looked on stage.

                  Shooting raw never gets bad.

                    You should reconsider working with that camera, if you are not into color at all. It's not made to match with anything other than LOG footage from comparably capable sensors.
                    Often enough I wish for a video camera: Capture, Offload, Done. To do that with the BMCC you are looking at 5-10k lens, 3k light and $500 filter investments. Or, you sit down and learn to be a colorist, which isn't feasible for everyone.

                      Nope, can't seem to learn how to be a colorist...

                        Too much red in some shots. Dial it back.

                            Gonna try it next to another bmcc to see if mine differs.

                              My BMPCC has the same problem with tungsten light: reddish skin tones, I partially solved with the HUE rotation parameter combined with HUE vs HUE curves in Resolve, unfortunately seems that BM cameras don't like tungsten light.
