And was the “seeing” directly optical by other human beings in roughly the same area as the man. Were there any additional technological or optical equipment involved in the seeing? Technology is important here. He is being seen through technological means.
In regard to the general context of “being seen by technological means,” is this some kind of medical scenario? Military? Does it have something to do with security at some location?
Is he wearing the overalls so that he can be differentiated from other people who might be present and seen?
Not medical, military, or security related. Not to distinguish him from other people.
Were the coveralls standard high-visibility coveralls? You know, with a high-visibility color like bright orange or green, and retroreflective stripes? Something like these?
Nope. Just regular overalls.
Is any material composition of the overalls relevant?
No, the material is irrelevant.
Is the viewer or man in water or on mountain?
No to any of that.
Is the color of the overalls different than his shirt?
Yes, the color of the overalls contrasts the shirt.
