Hi
Vandyke does not use a developer after exposer you develop it in water. It will bleach in
a strong fix.You must use a weak hypo.
I tone them in a gold toner;
You can see some of mine in www.pinholeformat.com
Take care

Oops. There goes another theory I thought was getting warm. You'll
have to pardon my lack of knowledge in chemistry here.
So, silver nitrate is used in Vandyke just to make the image? If that
is the case, why would strong hypo bleach it just like it would
silver? Or is the resulting image a combination of silver and iron?
By DOP process, are you saying that hypo is doing double duty here,
as both a developer and a fixer?
If you do come across your notes, please illuminate us about toning
Vandyke prints.
