Can you send this to the one guy on our Zoom calls who logs in 3 minutes after meeting starts, futzes around with camera/microphone/sound for 5 minutes and then 8 minutes into the call announces he’s online and wants to be filled in on what he missed?

From video production the one takeaway I have is key light vs backlight, webcams like key light and webcams struggle with back light
