 Use Adaptive fan mode to regulate the camera temperature. Noise occurs when the temperature from the
applied calibration map is not in sync.
POLARIZER AFFECTS IMAGE
SYMPTON
The image has a faint vertical rainbow artifact.
EXPLANATION
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.
BLACK AND WHITE IMAGE
SYMPTOM

POTENTIAL RESOLUTIONS
 Go to Menu > Settings > Look > Color, and check the Saturation setting. If the Saturation setting is set to a
low value, change the Saturation to a higher value.
