I tried to reach Hoya and rep, ><Snip> FLD's are anybody guess. Sing-Ray has their own secret receipt with secret sauces and everyone has their own guess as to make makes a discontinuous spectrum average bulb translate to 5500. Most pros I know don't use them at all. The create filter packs with magenta gels as a result of a pre testing on a certain location. My guess is in a different situation the Hoya receipt might have done you better than the Tiffen. And you are talking cheap Hoya, expensive Hoya might have an exotic concoction of waveleghts unknown to modern man. And a metal instead of plastic rim. Tiffen filters are two sheets of optical glass with a gel in between. That's six optical surfaces. Suffice to say 4 too many. The concept does not appeal to me. (Although NASA apparently thought they were OK for what that's worth) Give me one flat sheet of colored glass any day and I'll take my chances! Mark Rabiner
