I'd like to ask about the meaning of "reflect back against" in the following context:
If, as some have suggested, orbs are produced by an object outside
the camera reflecting light from the flash into the camera lens,
which is in turn reflected back against the rear surface of the lens by
the shutter, producing an image of the lens itself, then it should be
possible to repeat the experiment and obtain identical results.
Does "reflected back against" mean "reflected back from"?
