DSMC - EPIC/SCARLET DRAGON Polarizer Artifacts

Polarizer Affects Image


The image has a faint vertical rainbow artifact.


When using a polarizer with an EPIC DRAGON or SCARLET DRAGON® (with either a Skin Tone-Highlight or a Low Light Optimized OLPF), a faint vertical rainbow artifact might appear on the image. This artifact is not exclusive to EPIC DRAGON or SCARLET DRAGON cameras, and can occur on other cameras depending upon camera orientation and direction of the polarized light. The rainbow artifact is caused by a complex interaction between the scene lighting, lens, polarizer, OLPF, and the camera.

Potential Resolutions

  • Reorient the polarizer or the camera.
  • Avoid using a polarizer.
