Ultraviolet Reflectance Photography

UV Reflectance photography: This is where all visible light is excluded from the camera, and only the UV reflected from a subject is recorded. It is invisible to the human eye, though many animals e.g. insects and birds, can see UV light.

Basic Requirements:
• Camera with UV sensitive sensor (either converted camera, or DSLR such as a Nikon D40, D70)
• Lens which transmits UV (e.g. enlarging lens, such as the El Nikkor range – the older the better!))
• Filter which absorbs all visible light and infrared, and just allows UV to pass (e.g. Baader U Venus filter)
• Light source rich in UV (e.g. electronic flash with plastic UV absorbing window removed)
