Light source for Pyro negs
I'm not yet experienced with Pyro development, but I'm considering to give it a try. My questions concern the enlarger lamp for pringing pyro negatives. I read frequently that a cold light head is best for pyro negatives (presumably due to the yellowish stain on the neg), but I have a standard tungsten halogen lamp in my only enlarger, an Omega D2 with Super Chromega color head. I hope to use VC paper (Forte and Kodak). If the spectrum really must be close to that of a cold light head, is there a filtration offset that can be dialled into on the enlarger's color head to closely simulate the spectrum of a cold light lamp? Or, with regard to pringint pyro negs, is the spectral difference between cold light and tungsten halogen too small to be concerned about?

Or seamlessly adjust by varying the Yellow and or Magenta. 7y + 21m = Grade 2 etc. -- LF Website @ http://members.verizon.net/~gregoryblank "To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public."--Theodore Roosevelt, May 7, 1918 |

Regards, Szabo Yes I think the spectral difference of the light source would be a fairly minor consideration, unless hairsplitting the science is more interesting that making pictures to you. The stain of a pyro neg acts as a low contrast filter, for the highlights with VC paper. I don't think it has any effect on graded paper. The standard tungsten light source is contrastier than a cold light, so your move to pyro would definitly smooth out the tonal range. I think you'll love the look. My landscapes have taken on a far smoother, more realistic and atmospheric quality. Enjoy. |

I've seen some impressive prints made from pyro negs, but as Mr. Knoppow points out, this may be due, at least in part, to the printer being more meticulous with the process. I'll keep all this good advice in mind as I dabble with the new (for me) process.
