experienced several delays in unpacking our new house, so I'll announce it
now. I feel slightly conspiratorial in having recommended Xtol to Brian,
because after having abandoned his darkroom, he packed it up and sent it to
me a couple of weeks ago. In its entirity, gratis. He is much too modest
to let you all know that he gave it to a LuGger as a gift, so I figure I'd
better jump in here: it was a really extraordinary thing to do, generous
beyond reasonable expectation. I am sufficiently grateful to him that I am
trying to figure out what to do to express my gratitude and feel worthy of
this present.
Years ago, while traveling, I met an interesting character in Paris. I was
in a particularly angsty phase of my life and he told me "feel bad while you
can, tomorrow you might be fine". David Vestal wrote that it's good to be
old enough to be able to feel bad without feeling additionally bad about
feeling bad. As a general philosophy, I try to keep these ideas in mind
most of the time. Sometimes I fail: as someone who is enthusiastic about
Xtol and was enthusiastic about it to Brian, I find myself feeling somewhat
bad about that.
But about Xtol, I should explain:
I live in Adelaide, South Australia, where for a long time international
shipping would not take on drinking water - the only city in the developed
world to hold that distinction. It's a city of a million people on the edge
of a desert whose water supply relies on a river that gets most of its water
1000-2000km away and loses most of its flow to crop irrigation between the
source and extraction point for Adelaide. There are current discussions
about building a desalination plant for the city, which makes sense, but
that will have other impacts on energy use and the environment that need to
be managed. The tap water here kills Xtol dead, almost instantly. I don't
even consider tap water quality for photographic processes (I don't drink
it, so why would I mix chemistry for my precious photos with it!?) so I
often mention only in passing that you really should use deionised or
distilled water for mixing and diluting Xtol. If you use Xtol, please do
this, if only to stop me from feeling bad when you complain to the LuG about
spots, dead developer and other weirdness...
It's all about dissolved minerals. I am increasingly thinking that someone
should commercialise the late John Black's JB9 - simply because it has an
extremely long shelf life and is also highly resistant to water quality
problems. The reason for this is that its a 3-solution mixture (developing
agents, alkali and sulfite are kept separately until just prior to use) and
that the alkali is a proprietary formula that is very good at forming
complexes with ions in the dilution water, because the alkali itself is an
EDTA complex.
Xtol can need special treatment to get good results. That's probably
nothing for those of us who espouse its virtues to feel bad about, but I do
wish that Kodak had done some more testing and warned us.
