You can get optical devices that photograph infrared (beyond the visible spectrum) and so on.
They take something not visible to the human eye and represent it in a form where it is visible to the human eye.
You can fool around with your eyes and make 'em go cross eyed and fuzzy (for example) while taking a photo that is a crispy clear representation.
I'm short sighted (I see fuzzily) but the photographs I take a crispy clear.
There isn't THAT MUCH mystery in the idea that what we see with our eyes and what cameras detect can come apart.
But cameras representations are caused by (physical) phenomena. Cameras register light or whatever. If an orb is a light then an orb is a physical phenomenon...
