Photographic evidence
Photographic evidence is a reality testing technique that reinforces the distinction of self and other.
Hallucinogen users currently undergoing visual hallucinations can notice a distinction between viewing an object directly with their eyes as opposed to viewing an object through a camera's lense. The distinction arises based on the mental differences in interpreting physical distance. This technique is similar in manner to the visually impaired using a camera in lieu of glasses.
It is possible this technique is related to the perceived difficulty of using technology while undergoing a psychedelic trip.
