Here are some quick tips to look better for your next video chat - think Lights! Camera! Action!
Tip 1 - Lights
If the other person can't see you, you may as well just have a phone call. Fill your space with enough light to show your face. Be aware that natural light probably isn't the best.
Tip 2 - Camera
Look at your self view before the video chat. Make sure your whole face is in the camera's capture.
Tip 3 - Action
Keep your device steady. Don't have your laptop literally on your lap and don't run around house while video chatting on your phone. Think about what the other person is looking at.
