**What is the problem?**Time Lapse Video seems bleached out. It's hard to see any detail of the white filament.

What did you already try to solve it? Adjusted the lighting...helped very little.

Thank you for that list. I guess I can ssh in and make changes to these settings. I wonder if they will come into effect when I change and save or will I need to reboot? Hopefully I can make these changes and see the effect instantly so I don't have to test and reboot constantly.

Once you save, run sudo service webcamd restart and the changes will be picked up. A lot quicker than rebooting.
