Missing colors

Mon Sep 02, 2019 10:27 pm

Hey there, noon here.
Camera board installed on an old rpi. raspistill -o test.jpg out my front window produces a VERY pink image. Any ideas why? Almost like it’s missing blue and maybe green?

If your camera is a NoIR camera, then read this top pinned thread:

Or if you're using a NoIR camera in daylight, then that is to be expected.

Really? I don't see pink on 90fps NoIR v1 camera frame (robot through sunny grass):

Smartphone camera and human eye see grass differently:
