Problems with manual exposure and gain for Logitech c920

[onlyway]

Describe the bug
For Logitech c920 I have problem. Auto exposure settings are overexposing image, I'm trying to use manual one. But event setting gain and exposure to 0 makes screen almost white on camera.

Expected behavior
Exposure and gain settings should give ability to configure image properly.

Desktop (please complete the following information):

• OSX 12.4
• Camera Logitech C920

I have a similar problem with a Microsoft LifeCam Studio. Auto exposure gives an kinda usable picture, manual is either black (exposure 0) or overexposed as soon as I try to move the slider, it's like slider position left is 0%, position anywhere else is 150% and no change at all.
