After 40 or so years of Graded paper printing, the last 20 of which with an Aristo standard cold light, I was convinced to try VC papers. I got ahold of one of the Filter Drawer Aristo heads (CL45) with the V45 lamp to satisfy myself that the paper was up to Graded quality. I like the paper, trying several and settling on Forte, for a number of reasons, which I now am having great difficulty finding, like the rest of the world (another story). Anyway, I find that the exposures with this combination are extremely long (no matter what paper I use), and I'm not looking forward to very long exposures for 16 X 20 prints. I just read several old threads discussing this subject, but not this direct question - Can anyone tell me: If I buy the Aristo VCL4500 Dual Bulb head, will exposures be noticably shorter, not having to use filters? The filters are a bit inconvenient, but I don't mind changing them, it's just the long exposure times.
