[alt-photo] Re: dilution of pt/pd

As I told Loris, I  get beautiful gradation and range of tone in my  pt/pd prints from negatives prepared for the purpose with a density range up to something approaching a d max of 2.4.


What I want to do now is make pictures.

Terry, Here again is why molar works well. If one wants to play with the
look of your print (which seems to be what you keep harping on) and you want
to mix from power some ammonium based palladium, it is nice to be able to
work out weights required from the proportions of metal and salt in a
previous formula. It is quite easy to use the lithium or sodium or ammonium
salts.

I don't conversations about complicated issues causes people to leave the
list, it is the lack of respect or difficult interpretation of intent that
makes it no longer a satisfying experience.
