Honestly we are so normalised to high quality images via Instagram and YouTube and ppl/teachers hold themselves to very high standards without realising how long it takes to produce that media. (Tip you can improve video exp quickly with better -inexpensive-lighting + sound).

1. Raise the camera on your laptop to eye level. A few books will do if you don’t have a stand. It gives a better viewing angle

2. Lighting makes a bit difference . A desk light will do, but if you want a more even effect a ring light . I have this - there are others ITSHINY LED Ring Light with... https://www.amazon.co.uk/dp/B087TG413P?ref=ppx_pop_mob_ap_share

Obs there are way more expensive solutions to the above but most teachers didn’t go into teaching to become film makers . The above will give better results than sitting with you laptop on your kitchen table and speaking straight at it all day and will be good enough for most.

4. For the geeks a two screen set up makes life easier, one to see your class /audience. The other with slides etc you will be using. An easy way is smart phone as another screen and you log into the call as another user. The light suggested in 2 can be used as a phone stand.
