Gallery: Ultraviolet Photographs
My First DUVP: Flowers and Kairakuen Garden
The ultraviolet photographs in this page were taken by using two filters, B+W 403 and Wratten CC20C. The former filter is opaque to the visible light and transparent to the ultraviolet light, and the latter is a color compensating filter whose transmission factor is small for the infrared light. The reason why the color compensation filter is used is that the B+W 403 filter has a rather high transmission factor for the infrared light despite of its opacity to the visible light. For this region one should be very careful whether the image taken by using B+W 403 is really an ultraviolet photograph or not. If a nectar guide or a bull’s eye of flowers are taken clearly it may be safe to say that the photograph has been taken by the ultraviolet light.
