Why do computer cameras at home take different pictures in different situations? Does a professional camera or DV produce wide-angle distortion?

The photos and videos taken by the camera at home are of course distorted. The middle of the face will widen, the head and neck will shrink and become a round face, which is caused by the spherical distortion of the camera.

Professional video cameras or DV will also produce some distortion, but it is difficult for individuals to find it. Many distortions caused by wide angle are caused by improper use of wide angle or artistic needs. Don't worry too much about the current digital products, which have good quality assurance. Don't overemphasize the quality of products with extremely low prices.

If you want a good photo, you can use a digital camera or DV player, take it first and then upload it. If you want COS, upload it later. Don't take photos with the camera again, because those photos don't look good in COS.

Personally, I suggest buying a better camera.
