So am I, haha!!!
Just kidding. You know I will. Even with all the arrows I know will be shot into my back for posting such blasphemy.

Btw... nice to hear from you scott. [IMG class=inlineimg]/forum/images/smilies/biggrin.gif[/IMG]
The settings I’ve already posted here are not with any external filters. I just got some this week and was able to play with them for a couple hours one night. Hopefully it’ll turn into something good and then I’ll post info here.......I think (or maybe not given the lovely reactions to my attempt to share the joy with those other enthusiasts here on the forum).
Where is ScottyB that he can’t reply?

One word of caution is that the lens is very large on these units almost 90mm so it would be interesting to see which filters Dave is working with. Hopefully, he will post some info within this thread. (fingers crossed)
I’m starting to wonder about that ~90% number though. I lost all my files from the initial run because I had to turn in all the gear and licenses I had when I quit working for my previous contract employer. This time when I measured pre-filters I wasn’t getting that but I swear I did before. It’s baffling me what I’m doing wrong or differently, or if my mind is playing tricks on me. I know you did measurements, is that what you got too? I think it may have been when I was pushing the color brightness very high, but upon further subsequent viewings I noticed bad banding type issues and other anomalies so I had to be less aggressive with my settings.
I am using some 77mm filters for my testing because they were cheaper and at my test cost limit. They are big enough to cover the image exiting the lens. Now that I am pretty sure I know they work for what I’m trying to do, I may get larger ones for permanent use.
