[pure-silver] Re: Polycontrast Paper Performance / Cold lite

Ralph, thanks for your comments. I have to admit that Picker and even AA's 
writings of the 70s biased me toward cold lite / diffusion printing.  I 
bought my first cold lite head in the mid 80s. I have never owned a color 
head so I can't comment on that.  I do use a stabilizer and the output from 
my lamp is pretty consistent day to day. 99% of what I shoot is landscapes. 
I haven't reconsidered this decision since, and I appreciate your suggestion 
that perhaps I should.

I recall several changes that switching to CL made in how I printed:
1. Where did all the dust spots go?
2. My contact prints seemed to be very much more valuable as predictors of 
what I would get when projection printing the same negative.
3. I could now develop the negatives to a longer scale and get greater 
separation of the highlights, mid values, and low values. But, it requires 
long scale paper to see the benefit. (I like lots of midtones and softer 
presentations than much of what I see--and what appears to be popular-- in 
today's pictorial representation of landscapes).

I'm an amateur at this, and not sure I'm prepared to invest in a color 
head... on reflection I should reconsider the above decisions and see if 
they remain valid to me.  This past week I bought my first VC paper in over 
20 years. --My first trial is what generated this question. The writing's on 
the wall regarding fixed grade papers, so I'll continue working with the VC 
papers until I'm sure I know what to do regarding any equipment changes.

I'll try the tricolor filters if I can find them and then decide. Again, 
thanks, Ralph.
