Lifecam Cinema webcam: Adjust brightness and focus using camera app in windows 10. Settings Pro Mode
Disclaimer: Boring Video.
In this short video, I show that the camera app in windows 10 has the ability to adjust both brightness and focus for either manual or auto focus if your webcam supports it (my webcam is a 720p microsoft lifecam cinema.)
Good luck.
1) Open Camera app
2) At top left, click the gear icon to enter settings.
3) Look for "Pro Mode" and enable this advanced camera settings option.
4) Finally go back to the camera app in either camera or video mode.
To you left you will now see options to adjust either brightness or focus.
Good luck!
