But sometimes you can -- I don't know why.
This negative prints normally on silver gelatin (grade 2 or with no filter on VC paper), yet made a salt print just fine -- and it was a lucky first-time-with-salt-printing print, so I have no idea if I can repeat it.
It was double-coated (on Crane's Cover), with no contrast agent added.
Vaughn, how one double coats with salt print?
a. 1 + 1 salting and then 1 + 1 silver nitrate, or,
b. 1 salt + 1 silver nitrate and repeat?
(It's -a- I guess...)
P.S. I don't have experience w/ salt prints but w/ all other iron and iron-silver processes double coating significantly increases sensitizer contrast... Maybe that's how you've made it work???
The paper was soaked in the salt and gelatin mixture and dried.
Then coated with the silver, dried, then coated again.
Much later I tried to make a set of my boys. This one I had to coat 4 times to get a decent print. The neg makes a fine platinum print (on x-ray film processed at the hospital).
PS -- I am not 100% that this a scan of the salt print or the platinum print.
