Hi List,
After a long time I started to print again, and my first try was with
the albumen paper that worked very well in the past.
I used the formula:
Albumen 500 ml
Glacial Acetic Acid 1 ml
Water 15 ml
Ammonium Chloride 7,5 g
paper Canson lavis technique
The paper was coated twice with albumen and hardened with a hot iron.
The sensitizing was a 10% silver nitrate solution Brush applied twice.
The exposure was under a vapor mercury lamp 400 w at about 45 cm height
for 25 minutes.
The problem: uneven density all over the paper.
It looks like if the silver nitrate was absorbed more in some parts than
in others.
HELP
What should I do?
Thanks in advance
Joao
