stephen_john Posted June 16, 2005 Share Posted June 16, 2005 I wanted to use a light-green glass filter and discovered that it actually floresce. Does anyone know the major component in light- green glass filter that makes it to floresce? Link to comment Share on other sites More sharing options...
johnny_tergo Posted June 16, 2005 Share Posted June 16, 2005 I'm sorry, but I don't understand your question. What is floresce? Link to comment Share on other sites More sharing options...
miles_feigenbaum___dallas_ Posted June 17, 2005 Share Posted June 17, 2005 Are you taking photos of minerals that are flourescent using a black light source (ultraviolet source)? Many mineral sources are flourescent and can be photographed using black light. Link to comment Share on other sites More sharing options...
._kaa Posted June 20, 2005 Share Posted June 20, 2005 Spelling is your friend. The verb is "to fluoresce". The adjective is "fluorescent". Link to comment Share on other sites More sharing options...
Ed_Ingold Posted June 22, 2005 Share Posted June 22, 2005 It sounds like you have a piece of uranium glass (uranium oxide). Fluorescence will cause a dramatic reduction of contrast. You will have better luck with a Wratten-type filter, which uses gelatin cemented in glass. Link to comment Share on other sites More sharing options...
