Christina Lonsdale’s company, Radiant Human, tours the country with a portable photo booth, capturing “auras” on double-exposed Polaroid film. Inside Lonsdale’s mini geodesic dome, a special camera connects to two metal hand sensors that purport to translate a subject’s personal electromagnetic field into billowy colors. “Everything from your ears up stands for your state of mind,” explains the Portland-based photographer about this shot of a client named Katie. “Purple is a very visionary color, indicative of having a high-concept, creative mind. In the lower left, there’s not really a clear color there. That could mean she may not be fully grounded, which is common for purple. In the lower right, it’s a tan, which indicates she may not like to take risks.”
