The instructions say: "10-12 grammes of potassium ferrycyanide [...] 20-25 milligrammes of ammonium ferric citrate" Instead I used 20-25 grammes of ammonium ferric citrate. On the video it seems to be double the amount of potassium ferrycyanide. Anyway, we got lovely blueprints! I used dried leaves, cutlery, ruler and pencils, feathers and so on in the various blueprints. Amazing effects! You can enhance the effects put the materials on the paper without glass plate. If the materials move a bit during the process, it doesn't matter, because in that way you get lighter and darker spaces of the blue, which give a vivid effect. Good luck!
Muchas gracias por este video, no conocía este procedimiento. :^D Por cierto, Angela Tellier transmite mucha tranquilidad, me encanta su manera de hablar y sus gestos corporales, es muy linda de ver. :^3
Yes. But you won't use them for the blueprint itself, for it is a particular photographic process (taking it in a broad meaning). You may want to use watercolour to paint over a blueprint, or use the blueprint in a larger project, where it's part of a big panel, for example.
