UV photography has been used by dermatological laboratories since the era of film photography. This technique was then used by the R&D centers to show the protective properties of dermatological and cosmetic products against UV radiation from the Sun.
UV photography has many obstacles. Ultraviolet light, or light from 200nm – 400nm in wavelength, is notoriously difficult to image with normal camera equipment. A normal digital camera will record images in the visible light spectrum, or 400nm – 700nm in wavelength. To unlock sensitivity to those shorter wavelengths, a camera has to be physically modified to allow passage of light below 400nm.
