8 way test
This is a test of changing exposure, differing silver nitrate quantities in the sensitizer application, and differing silver nitrate quantities in developement.
I was trying to figure out what varies the tone and density.
Lots of coating flaws and areas here.
Ag here means "Aceto-nitrate of silver" as described by Talbot.
"Lo Ag sens" means .03 ml Ag per 1 ml water.
"Hi Ag sens" means .06 ml Ag per 1 ml water.
"Lo Ag dev" means a longer gallic development followed by dev with 1 part Ag to 8 parts gallic.
"Hi Ag dev" means a shorter gallic dev followed by dev with 1 part Ag to 2 parts gallic.
Each image has +1 stop (left) and "normal" exposure (right).
A: Hi Ag Sens, Hi Ag Dev
B: Lo Ag Sens, Hi Ag Dev
C: Hi Ag Sens, Lo Ag Dev
D: Lo Ag Sens, Lo Ag Dev
Adamson's process (double iodide of silver), acidified Canson Marker paper. Washed in RO-purified water followed by tap water, then fixed in 5% hypo and washed.
