When was the last time you had a face-to-face meeting looking up people's noses? If your laptop is on a low desk, that’s what the other people will see! The camera is often at the top of the computer screen, so if you can, try raising your screen. Ideally, you want the camera to be at eye level, though it’s still worth trying if you can’t fully achieve this.
You can get laptop stands for under £30 on Amazon if you want a long-term solution, though a pile of books or whatever you have to hand should suffice!
