I have an ancient DII enlarger. I usually use it with an Aristo cold light. Is there a colorhead available for this thing, and if so, what is it called? I need to know what they are called so I can search for it online. My options are to either get a colorhead, or switch back to the condenser head and use CMY filters. I liked the condenser head fine; but I would have to rig up glass negative carriers because I always got negative popping on exposures over 10s.
