there are 3 cameras;
in gameplay settings at the bottom are your tick boxes, dymanic camera is what you are calling 'follow', shake [which i personally find makes me dizzy] and combat camera which is very buggy and the one that changes the most... there is also the O key bind for the 'tatical' camera which is just the dymanic turning on or off
as of the patch 8 combat camera should jump to a face frame shoot of the character when a crit happens to 'look dramatic'... it doesn't work correct unless the character and the target are both at the same level
as of patch 9 the camera [and the selected character] will jump to the main character at the start of 'MOST' talking scrypts i.e, anytime a combat [ends] or cut seane happens the main character should be auto selected... this change casues a few issues, one of which is resetting camera settings
the big issue is Larian designed the area without taking the camera into account and it tends to get stuck so they made a few changes in order to try and fix that or at least make it happen less
