I don’t get why there’s negative reviews. It works awesome!

I have the Logitech C920 1080p hd webcam and this app lets me easily adjust the brightness, contrast, saturation, sharpenss, white balance etc as well as have the ability to zoom, pan and tilt and even manual focus. It also allows you to turn off the backlight compensation which for me was a lifesaver because my room by self is really dark and would illuminate my face way too bright and now I can turn that off.

It’s a great little app and has dramatically improved my youtube recordings as well as just looking better lit and sharper when I have skype convos :)
