In the film Velvet Buzzsaw, there is a unique piece of reflective art, 'Sphere'.
There are a couple of camera shots where we see the sphere, but the camera cannot be seen in the reflection:
How are these camera shots made?
This can be accomplished with simple CGI (computer-generated imagery). In the original shot, the camera is visible. Before the movie is released, digital artists simply replace the reflection of the camera with something that looks like the reflection of the room.
This is the same technique that is used to hide the wires & ropes that hold actors up when they're "flying".
