Re: Re[2]: HIE Devs - Perceptol ?

[Larry Bullis <lbullis@xxxxxxxxxxx>]

This is a reply to absolutely the first posting I have read on this list 
having just replied, so I'm flying blind.

I have done a fair amount of testing and work with older fine grain 
developers and HIE's first cousin, 2475 Recording Film (which is 
currently on Kodak's discontinuation path).  One of my favorite 
combinations is 2475 and MCM 100, an old paraphenylene diamine / catechol 
formula which can be found in Aaron Sussman's _Amateur Photographer's 
Handbook_, a common (and wonderful) textbook from back in the '60's.  I 
found some of my notes on this last week because I have to revive it for 
an upcoming job.  As I recall, the time would be about 24 minutes.  I can 
check this out.

I'd be happy to dig up the formula if anyone is interested.  This is not 
an easy developer; it is hard to mix, doesn't keep, toxic as all get out, 
expensive, and you lose a whole stop.  But the results are nothing short 
of incredible, IMHO.  Grain is still there, of course, as an inevitable 
textural element, but it is tight and clean.  Quite beautiful really.

While I haven't tried this with HIE, I am absolutely confident that it 
will work because all of my tests have shown that HIE and RE are 
virtually identical in all respects except for the specific spectral 
sensitivity of the two films.  I treat them exactly the same in some of 
my other developers and the results are the same.  In fact, I develop 
them in simultaneously in the same tank.  And, if I'm shooting HIE but 
wishing I had RE instead, I just take the filter off and visualize RE.  
It's not exactly the same, but not a bad approximation.  I could use it 
every day.
