Each of these portraits by photographer Carlo Van de Roer uses an AuraCam 6000 to capture not only the subject but the color of their aura. According to the Auracam 6000 website (possibly circa 1995), the Auracam uses hand sensors connected via cables to the camera. Polaroid instant film is put into the camera and when the 'customer' puts their hands onto the sensor, the camera gathers 'biofeedback parameter data.' Basically, the thing translates the electromagnetic field of a person and projects it as a colorful field around the film.
"The Auracam 6000 consists of one or two hand sensors which are connected through cables with the camera. Polaroid instant film is put into the camera and is adjusted and aligned to the customer. Once the customer puts their left and right hand onto hand sensors, the AuraCam 6000 begins to gather standardized biofeedback parameter data through the hand sensors. The measured points of resonance are connected with certain organs and the electromagnetic field of the person; this information about the energetic and auric qualities of a human being are then delivered to the camera. Through a patented operation, these parameters are projected as a radiant, colorful aura field around the body onto the Polaroid film, along with the image of the personGood portrait photographers always seem to capture their subjects during a unique, spontaneous, or genuine moment."
