If Judy is interested, I will write this article for PF even *if* View Camera
invites me to write. View Camera might have more readers and have good
interest in alt. photo, but PF is totally dedicated to alt. photo. We need to
support alt. photo!

Actually the tests that I will do are not comparing pyro with other developer.
I didn't mean that now I can do everything that pyro can with say MQ developer
(I haven't done pyro, so I don't know), but I was simply explaining that my
last-year question was not whether pyro gives different result but whether the
result can be achieved with common developer.
What I said in particular was that particular *one *effect of pyro, namely the
adjacency effect, can be achieved with common developer like D76, or if the
contrast is still too high, a low-contrast developer like LC-1. The
(controlled) adjacency effect will of course, enhance apparent sharpness of a
print. This can be easily seen from the negatives, a comparison of silver
prints, and if my gum printing has improved by then, I will make a gum print
(in fact, I am thinking about doing that "jumping out petals.")

I got that once too with dilution like Dektol 1+20 and processing an enlarged
negative after I have processed a few test strips. In the place where dark
gray meets light gray, for example, I got about 1/8" of edge effect where one
side is completely clear and the other side is darkened! The developing agent
must have been close to exhaustion.
But all this is fun, isn't it? :)
