Have been reading the mail on the Hoya FL-Day Filter and I keep reading that people are asking how these filters are being mounted other than in a hush box. I would like to try this but I don't want to glue this thing on the front of my projector. I can't think of any reasonable way to mount a 49 mm filter over a smaller recessed lens and hole. Am sure if anyone has a reasonable answer other folks would like to know how to do it and a picture would be worth a thousand words.
