    I been noticing a green banding in Epic-W towards the skin tone.

    I have tried all 3 DSMC2 OLPF with the same outcome.
    I know that the HELIUM Color Science is not out yet but take a look at this, Do I have a bad sensor? I include the R3D files in the last link.

    Shot on ISO 800, Canon 50 Cine lens. RG4 DC2

    Very, very, very well known CA from the Canon 50mm T1.3. Stop that lens down to T4-T5 and you'll see that go away for this specific lighting scenario and contrast ratio.

    Thank your for the reply Phil, But I brought down the image to show more of the problem. is this a Chromatic Aberration?
    you coud see it clearly how it lines up between the whites and green.

    CA fringing is usually green or purple. This definitely looks like CA to me. Its an easy test to do against white.

    It also shows in a weird way, usually when I see CA it blends smoothly with no sharp edges.
