Standard cold lights are really meant for graded papers, giving off blue light. You can add a #40Y filter in addition to the VC filter, but it cuts off so much light output that in practical terms, it's not worth it. For doing a lot of VC printing with a cold light, it's better to switch to a V54 lamp that gives a broader spectrum. Or even better, in my humble opinion, would be a colorhead. I much prefer to dial the filtration into the head itself rather than using filters under the lens. And a colorhead with a voltage stabilizer gives more repeatable light intensity than a cold light. One important note: most VC papers don't respond well to extremely low contrast ranges. Many won't achieve a good black with grade 0-1 filtration and have a hard time getting good low value separation. Shadows turn into mud. I've found Agfa MCP and MCC probably the best in this regard. A better alternative (besides a graded paper) is to use a higher contrast filtration (say grade 2) and develop in a low contrast developer like Selectol Soft. This will bring it down to between grade 0-1 but maintain better low values. In my experience, anyway. :) Good luck! -Charlie --- "J.
