In a message dated 00-02-26 15:15:25 EST, you write:

<< Has anyone tried this? I'm thinking of using a Gossen Luna Pro digital
 and trying it out unless someone has experience with the disassembly of
 meters and can recommend a better choice. >>

This is all in red, for some reason.  I hope I'm not spreading the red color 
to everyone else.  It always seems to appear when someone Mimes us.  Anyway, 
I have taken my Gossen Luna-Pros/Luna-Sixes apart at various times, and have 
never found a blue filter in there.  In fact, you can see the  photo-diode 
pickup when you push the button and look in the operating end (not with the 
incident light dome in place).  I made up a suitable adapter (a black plastic 
top from a bug spray can) which just holds my 67mm #87 filter in the open 
end, and I cut the closed end with a large rectangle to slip over the end of 
the Gossen.  Then I read directly through the filter.  I'm happy with the 
system I've devised and, as I've said, I have no idea about this mystery blue 
filter.  I think it must have been a different meter .
