It is amazing to me that we still have such a distance between people on this. Some people have basically created a tv studio at home with a nice set, good lighting, nice background, quality camera, and mic. Having a video call with these people is a nice and smooth. And somehow we still have people that think sitting in a noisy, messy room with the sun at their back and using their laptop's built-in mic/speakers is…
On the one hand, I'm sympathetic that not everyone has a place to create a TV studio at home. On the other hand, there are easy ways to block out the light from a backlighting window and to add a key light.
It's a case of empathy. Do you have enough empathy to check how your video looks and do simple changes?
