I just bought an used DeVere 507.
I develop mostly in pyro and print on VC paper (most times with no filter) because, according to G. Hutchings, the yellow stain allows to get very subtle tones in the highlight areas, which is what I am looking for.
the question is, if I ever tried to adapt a cold light head to my enlarger, would its spectrum diminish the advantaes of using pyro?
What would be in general the advantages or disavantages of using a cold light with pyro?
