Why your webcam image looks bad
Most bad webcam footage comes from three issues: the main light is behind you (backlighting), above you (raccoon eyes from overhead shadows) or too dim (noisy, grainy image). A screen-based webcam light fixes all three by placing a broad, controllable front fill source exactly where your camera is pointing.
Prop your secondary device screen-side toward your face at roughly eye level, about 40 to 80 centimeters away.

Max out your hardware brightness in your OS settings, then tune the brightness slider here until your face looks evenly lit. Go fullscreen so the display behaves like a true panel light with no browser chrome.
Match screen color temperature to your room
If your room has warm incandescent bulbs, shift the webcam light cooler (4500-5000K) to counteract the orange cast. If your room uses cool daylight LEDs, warm the screen light slightly (3800-4200K) so your face doesn't look sickly blue. Screen lighting is the only webcam-light solution with this kind of per-call temperature control built in.
