It's true that there is a problem with VC papers, though I think Zone VI has fixed that probelm. But there is no difference between cold light and other true diffusion sources as far as tonal scale. The difference comes with adding condensers into the light source, with no diffusion. You are right, there is some difference in acutance, but with a Leica enlarger, and film through a Leica, I've yet to see any loss of sharpness. IC, IIC or V35. The main differnce is that film developed for condenser light, used in a V35 means you'll be using 3 1/2 and higher filter settings with the VC head to get normal prints. ========================== Eric Welch Grants Pass Daily Courier
