    I need your help professional DoP's!

    Can you please tell me what could cause that interference on the dashboard? I have guesses bu tit would be nice to be certain (well as much as possible) as it's difficult to get this car back for reshoot.

    I can tell the shutter angle: 180, Fstop:4 ISO:1600
    Camer URSA Mini G2
    No ND filter
    No polarising filter

    Other DoPs are managed to do without so I need to know what went wrong

    Thank you for your time!

    Let me know if you need any more info!

    This appears to be what is known as Color Aliasing or Moire and occurs with cameras that have a weak or don't have a Optical Low Pass Filter/Anti-Aliasing Filter.

    What ever the detail and/or pattern is on that dashboard, the higher frequency detail is causing the artifact.

    Most BMD owners using the cameras for professional work purchase 3rd party filters from companies like:

    I would not allow a BMD camera without one of these filters on any job as the post production fixes for this are time consuming and expensive.

    If for whatever reason you do have a filter in there or not, there's also a slight chance of it being a linear polarized versus another polarized surface, but this looks like Color Aliasing to me.
