Radiation and Conservation

Light can help us observe but it can also be damaging.  Optical radiation, especially shorter wavelengths can destroy colors over time.  The textile industry developed a visual standard, the blue wool scale, in order to ascertain the amount of damage and the time it takes to occur.  I introduce you to some work of a M.S. student to replicate such using a calibrated spectroradiometer connected to your smartphone that can observe changes to works of art.  I also show some examples of why this is important.
