How does enhanced visual equipment aid investigators at catching paranormal activity?
Since the human eye perceives only a small sliver of the electromagnetic spectrum, digital audio/video is utilized to broaden their senses. This equipment can capture moments in great clarity and into the infrared range. Various filters can assist to broaden their range into the ultraviolet or infrared. Thermal imaging measures infrared radiation emitted by all objects (black body – radiation) and allows investigators to navigate in near/total darkness. Night vision allows the viewer to take advantage of non-visible sources of electromagnetic radiation (near infrared or ultraviolet).
