Proper syntax for libcam_params?

[JChristensen]

In my camera config file, I added libcam_params saturation=0.5 but this did not cause any change in the images.

I can run rpicam-still --saturation 0.5 -o image.jpeg and the image has reduced saturation as expected.

Looking at the log file (attached motion.log), Motion appears to have recognized the parameter, so I may be misunderstanding something.

Environment:
Motion version 5.0.0-git-20250224-6e685d8
OS: Debian GNU/Linux 12 (bookworm) aarch64 (Raspberry Pi OS)
Host: Raspberry Pi Zero 2 W Rev 1.0
Kernel: 6.6.74+rpt-rpi-v8
Raspberry Pi Camera Module 2

Thanks in advance ... jc

Does it work if you use Saturation=0.5 instead of saturation=0.5?

[JChristensen]

Ha! I thought I had tried that earlier. I tried again and it worked! Thanks very much!

PS: I am using the "NoIR" camera. With Motion 4.x, the images always had a pink-ish cast, which is understandable, but with Bookworm and Motion 5.0, they were quite a bright red. Someone else must have been making that adjustment previously, but all's well that ends well :-)
