You may try the following function:

ExtrahiereViews[ll_]:=
  Flatten[Union[Extract[ll,Position[ll,#]]&/@
  {ViewPoint->_, ViewCenter->_, ViewVertical->_,
   ViewAngle->_, ViewVector->_, ViewRange->_}]];


Call it and paste the graphics you moved with your mouse as
argument. I use CMD+Shift+L (copy output from above) for that purpose
