Aristo V54 bulb, Zone VI controller, and contrast?
I was recently doing some step-wedge testing and noticed
that anything higher than grade 3.5 looked prettmy much the same. Here are the details: Zone VI cold light head (Beseler 45) with Aristo V54 bulb, less than 2 hours total usage I guess Zone VI intensity controller Kodal Polymax filters (relatively new, high contrast barely used) Luminos Flexicon VC (= Kentmere Fineprint VC, I think), both in fiber and RC, also Forte Polymax fiber Silverprint Tektol neutral and Tektol standard developers The Aristo bulb is supposedly designed to work "better" with VC papers. It occurs to me just now (that I don't see any available darkroom time in the next couple of weeks, and being Sunday I can't ask Aristo) that I normally use my Zone VI controller with the intensity set at "F" to give me a little longer exposure at f/8. I can achieve stabilisation typically up to K or L once the bulb is warmed up. Here's my question - has anyone ever done experiments to assess contrast grades vs intensity with the Zone VI controller? If so, this could save me a bit of time and paper; if not, I'll do it myself and post the results, though it could be a while... TIA. Steve |
