Any Omega enlarger owners out there using the D5 condenser lamp house who know h ow to actually use omega's metal "filter holder" bracket?:
It's a two piece over-lapping black flat metal bracket device measuring 6 1/2" b y 6 1/4" The slightly larger piece has 6 short silver pin registers and the sma ller piece fits inside and has corresponding holes which align with the pins. (w hen two pieces placed together, there's an internal opening appx. 4 3/4" by 4 3/ 4" wide.) Additionally, the filter holder has the following instructions printe d on it: "Filter holder should only be used in position no.3. When condenser is in position no., 3, place filter holder on top of condenser".
I ordered it along with my Omega Pro lab II Variable Condenser enlarger, feeling it was necessary somehow to properly hold the 6" by 6" VC printing filters cus tomarily used in the D5 head filter drawer. When I got it however, I couldn't fi gure how to use it or why it might be needed. First, it seems the print filters would have to be hole punched by hand to align the pins. Second, it seems possib le to get by fine without the whole apparatus in the first place by placing bare print filters on top of the condenser lens.
Not wanting a perfectly good piece of gear to go unused, could any veteran Omega users out there tell me: First: under what conditions might this bracket be bes t utilized? Second: Which position in the condenser lamphouse filter drawer is "position no.3"? Is it the top most or bottom most slot?
I phoned Omega, and they weren't much help at all answering these two questions. Thanks in advance for your help. Andre
