[Alt-photo] Re: Was Sulfamic now Argyrotype

[Serdar Bilici]

Hi Marek,

Let me squeze in a few thoughts...
When I tested HCl with canson montval and FA TW HP (and schoellerschammer)
the dmax with the argyrotype was not bad. Blacks were better than single
coated VDB but not as good as double coated. I did not test HCl with FA EW
SP. And I haven't toned the prints.

Dmax I get with sulfamic acid treated papers were better than HCl treated
papers. And I must say, I have decided not to do VDB anymore after having
such good blacks using argyrotype and SA treated papers. I got great dmax
with FA EW soft press using argyrotype(untoned), the blacks are identical to
the results with masa paper. (I often compare my results with masa paper, I
consider its results as a very good benchmark) 

If you can compare the results after trying sulfamic acid treatment, I think
that would be quite informative for everyone. Gold toning was a parameter I
was not able to test by that time, and the toning overall has quite a
dramatic effect on dmax.

Best Regards
Serdar

Thanks Loris,
 
I tried a test strip yesterday and it worked great. Great DMAX, beautiful
tonal gradation. Today on the dry test stip I noticed some general fog
(stain). I can think of two possibilities. I used hydrochloric acid (muratic
acid) to wash  the FA soft press paper. Any residual chloride would be
incopatible with the silver chemistry resulting in some silver chloride
precipitation. I also did not acidify the water for developing. Any more
insight from long time argyrotype practitioners?
I really like the pruplish gray of the gold toner highlights Good news is I
picked up a 1lb of sulfamic acid at Home Deport for about $6 for furter
experimentation
