Quote - The picture on the right (on the picture that I posted), is taken from the main camera angel.

Huh? The picture on the right is taken with the Face Camera, not the Main Camera. It says so in your screenshot. I don't know what you mean by "main camera angle". The important thing is which camera you are viewing with (as stated in the Document window) and making sure you are adjusting the parameter dials for the same camera.

But anyway, it seems this is a problem for you on all cameras, so I really don't know what's causing it... sorry.
