What causes the pattern seen on the image (it is a still from a video)? This doesn't seem to be a Moiré. It seems to be largely related to the camera or the filter (the pattern is fixed and aligned with the camera). The image was taken through an optical bandpass filter.

    Can you provide some information about the image? I have no idea what it shows, at what scale etc. – this.myself Apr 18 '18 at 8:55
  • Sorry, I don't know much about photography and I don't have much information about the image either. I know it is digital, uses an Nm filter and shows shows 2 regular white clouds in a blue sky. – JPR Apr 19 '18 at 10:19

Nm filter? Do you mean a [some number of] nanometer bandpass filter? If so, that's probably what is causing the pattern.

  • Yes, I did mean a nanometer bandpass filter. I didn't have much information to go on, but your answer was still helpful! Thank you. – JPR May 16 '18 at 11:12
