One thing my evil service provider does (maybe everybody else's does too?)
is put the % of an e-mail you've read on a line in the upper right hand
corner. I try to remember to check that figure before leaving, as
appearances can be deceiving.
Two other notes on current issues: Terry said potassium citrate was
expensive & hard to get: Last time I ordered (about 3 years ago) was $12 a
pound, which is about a lifetime supply, from Photographer's Formulary.<
The message I received from Dennis announced itself with the number of
bites appropriate to his intro so the list of papers got lost in cyber
space.
Dennis's list seems a very useful contribution and I eagerly wait it.
As to potassium citrate Judy is quite right, if you go to the right
supplier it is cheap but there are those on the doorstep, who one is trying
to tempt into alternative processes, who are used to buying their goodies
from the corner store. The pharmacist down the road from the college, where
I find it convenient to run my workshops, let me have a kilo jar one day
but told me that once it would have been his winter's supply of cystitis
cure ! Once the neophytes are bitten they will acquire the specialist
knowledge but if they can use citric acid from the supermarket to make a
salt or an albumen print or a brown kallitype so much the better. These
three acids appear to be repeated by recipe printers over the decades and
everybody accepts that print is equivalent to engraving in stone so that
they must be used.
Klaus and Derek have rather confirmed my experience that it does not make
all that difference if you interchange the tartaric acid, citric acid and
potassium citrate or leave them out.
To take the matter a little further, adding oxalic acid to the ferric
oxalate in the sensitising stage of making a platinum print does not seem
to make much difference either.
As to UTC, I assume that this is what those of us who sit on the Greenwich
meridian. 0 degrees, refer to as GMT or Greenwich Mean Time. I have
received mail from what was tomorrow from people also in the 0 degrees
time zone, five miles away, which seemed strange until BST was taken into
account.
