I totally support Judy's comments as to the quality of silver nitrate
brands etc. It does make a difference but along with paper quality, water
quality, sun quality etc, there are so many variables in salt printing as
to make it most unscientific! As I said in my earlier response that is what
makes it exciting; to achieve a colour or whatever and try to reproduce it
again. I have achieved near blues and reds but never been able to reprodice
them even from the notes I made.
