What happened to Devices -> Cameras in Windows 10 settings?

Solution 1:

Regrettably, MS has removed most of these setting from the control panels, though if you have the MS Camera application installed (it is packaged with Windows), some global settings can be adjusted with it.

However, How2Do suggests a third-party application, Webcam Settings Tool, about 6 MB for the zipped portable version, screenshot below. There are many alternatives, as well. Before installing any application, check it for malware at VirusTotal or elsewhere.

Though Windows may miss the mark in some areas, at least it is currently an open platform, allowing third-party tools such as Webcam Settings Tool and Open-Shell Menu to make amends.
