I took a trip to the Palouse area of Washington State last weekend. I developed a couple of rolls of the Delta 100 6x7 I took with my Mamiya RB67 and made contact prints. A few of them looked worthy of enlarging, but I've stalled on the first one. To make it short, the contact shows a nice tonal range and contrast, but the enlargement is just plain muddy, to put it kindly. In the print of the enlargement, there is hardly any tonal separation in the clouds - just a fairly uniform sea of mud. I've posted a scan of the contact and enlargement in the technical gallery, but the scanner "fixed" the enlargement so that the scan looks much better than the actual print of the enlargement. I'm used to having the enlargements need some work to look as good as the contact, but this one is so bad I haven't been able to come close to the contact in spite of many tries changing the filter and enlarging time. No matter what I've tried, the clouds (and other whites, like the barn roof) turn out muddy. Both the contact and the enlargement were done with a 2 1/2 filter, using the same lens and the same paper (Arista Edu Ultra). The lens is a Schneider-Kreuznach 80mm f5.6 Componon that I've used previously without any issues. The photo was overexposed and the negative is quite dense. Still, the contact turned out fine with a longer than normal exposure time. Am I beating a dead horse here or is there something I'm missing?
