Re: [pinhole-discussion] What is a silver print really?

2003-01-25 Thread Jean Daubas
Hi all,

I just looked in one of my favorite Photography books :
Looking at photographs - a guide to technical terms
by Gordon Baldwin. published by the J. Paul Getty Museum in association with
British Museum Press. Copyright (c) 1991
ISBN 0-89236-192-1

Here is what Gordon Baldwin writes  (a short entry since author does not
appreciate the term !) :;-)

 SILVER PRINT : This a shorthand term for what should be called a GELATIN
SILVER print, meaning a paper coated with a gelatin emulsion containing
SILVER SALTS. The term should be avoided because most black and white
photographic prints contain silver, and the term is therefore too inclusive
to be useful .

By the way, Gelatin silver print and Silver salts have much longer
definitions in Baldwin's book, but if I begin to type in my post all the
excellent explanations, I'm sure we shall end with the 87 pages of Looking
at photographs in the same message !
Hope it helps,

Cheers from France
Jean

Re: [pinhole-discussion] Alternative processes

A ready made factory product is an alternative process? What are you
referring to specifically, Steve, jello? Thomas Kinkade? And you are right.
Silver nitrate technically is no alternative. In the strictly historical
sense of the word, it is a PRE factory process.

The process materials are referred to as 'silver gelatin' and that's because
the silver halides are in a suspension of gelatin, layed down on the paper.

Alternative to that, a ready made factory product is an alternative process.
Or alternative [to silver gelatin] post factory process.

 The albumen and kallitype processes use silver nitrate, but aren't
referred
 to as silver prints.
