thomas_jakubowski Posted January 20, 2000 Share Posted January 20, 2000 Does anybody know which filter to use with daylight film and a light source that is nominally rated at 3000K? A quick glance at Kodak's Wratten Web site indicated an 82A filter for an incandescent source. My source is a special "warm" fluorescent light that I use to help combat seasonal affective disorder. It's here, paid for, it works for SAD, what else can I do with it? Link to comment Share on other sites More sharing options...

bobatkins Posted January 20, 2000 Share Posted January 20, 2000 Most fluorescents are wierd. Though they may have a "nominal" color temperature, their spectrum has spikes. All you can do is shoot some film (try the 82A I guess) and see what color things turn out. Typically of course, fluorescents give a green cast which needs a magenta filter to cancel it out.

jamie_curtis Posted January 25, 2000 Share Posted January 25, 2000 Color Temprature and color balance are not the same. For most fluorescents, you need to start at about 30 CC Magenta to reduce the green cast. Rosco has a gel (#3308) that will give you a good starting point. This gel is for your light, not your lens. If your light is some funky mixture, your much better off experienting with $6 gels than $60 filters. Link to comment Share on other sites More sharing options...
