I am interested to learn more about platinum printing process, new to this area.
Appreciate it if someone experienced explain:
1) The chemical required and the places to purchase
2) The best paper for the process
3) The process involved (stepwise including quantitative and qualitative chemical compositions for developing)
4) The best way to frame platinum prints.
And also let me know drawbacks of the process, if any (except the cost) compared to silver printing.
