When they sense invisible electromagnetic wavelengths like xrays or microwaves and “assign” colors to completely invisible wavelengths then that is false color imaging. Possible to do with the sun… but unlikely with an amateur rig.

Not OP, but solar photography requires super dense filters so like sunglasses alter what you see from “actual” the filters also alter the image from “actual” yet this is what would “actually” be “seen” by the camera. So yes and no depending how you want to interpret “actual”.

A policeman? is that unusual?

TIL. tho maybe TMI.
