Hi all. <p> The next toy on my list for 2001 is the Zone VI 8X10 VC enlarger by Calumet. I'm curious about the accuracy of some of the claims Calumet makes about the enlarger. <p> I emailed Ilford to ask them and they have not responded. It's not that I don't believe Calumet's claims about the structure of VC paper emulsions; I'm just curious about their claims regarding the effectiveness of their dual cold light grid. <p> Anyway, here's what Calumet says on their web page. If anyone has practical experience with this enlarger or the general design; your input is most appreciated. <p> "Heres how it works. Variable contrast papers are made up of two different emulsion layers: a low, or soft contrast layer sensitive to green light, and a high, or hard layer sensitive to blue light. The variable contrast head features two light grids, one green and one blue, each with its own rheostat. Print contrast is controlled by varying the intensity of these soft and hard grids. This system allows the ability to adjust contrast within the high and low values independently, and in one exposure. Because there are two different tubes projecting two different spectrums of light, its like making two exposures in one, each hitting and effecting the two layers in the papers emulsion."
