> Contrariwise, when you are speaking/presenting, use an external camera (the one in your laptop/ipad/phone is optimized for thickness and thus the lens sucks) and a good soft key light.

I recently did a fair bit of research into this exact setup and landed on a Logitech StreamCam and a Elgato Key Light.

Well worth the money if you’re interested in achieving a high consumer grade level of quality, just be sure to purchase an adapter for the StreamCam as it is (infuriatingly) wired with a USB C connector.
