Hi, try {vp, vc, vv} = OptionValue[Plot3D, #] & /@ {ViewPoint, ViewCenter, ViewVertical}; Plot3D[Sqrt[1 - x^2 - y^2], {x, -1, 1}, {y, -1, 1}, MeshShading -> {{Yellow, Orange}, {Pink, Red}}, Mesh -> 10, Evaluate[ Sequence @@ Thread[{ViewPoint, ViewCenter, ViewVertical} -> {Dynamic[vp], Dynamic[vc], Dynamic[vv]}] ], MaxRecursion -> 2, WorkingPrecision -> 20, PlotPoints -> {100, 100}, Boxed -> False, Background -> Black] to save the camera position and orientation in vp,vc,vv and use the values when you save the graphics.
