Abstract

LED (Light Emitting Diode) lighting has been widely used as a major light source to illuminate photographic prints. However, the effects of LED lighting on image stability of prints are not clear. Light stability tests were carried out using some commercially available white LED lamps, and the fading behaviour was compared to the standardised Xe light testing, which simulates indirect sunlight indoors. It was clarified that fading under LED lighting is less than under Xe lighting, but it correlates well with Xe testing regarding the order of print materials in light stability. The effects of the correlated colour temperature (CCT) and the excitation wavelength of LED lamps were also studied. As a result, it has been confirmed that the dependence on the CCT is not significant, but LED lamps with shorter excitation wavelengths are more harmful to the light stability of photographic prints. Based on these results, a guideline for determining the standard test condition for LED light stability of photographic prints will be proposed.
