Black is beautiful !

Finally, after one year of "try and error" with cyanotypes, toned with tannic acid, gallic acid, tea, or coffee....or blahblahblah.......I´ve got it.....my first really "black" Cyanotype on my new favorite paper "Lukas OSAKA". Normally the toning process results in a lot of weired color cast like greenish-violet-brown-blue-black colors, but yeah....on this new paper I´ve got a beautiful clean warm-black tone. In this case I toned the wet unbleached cyano with tannic acid immediately after the washing process. And it works..many thanks to the "Schoellerhammer" company for this beautiful watercolor paper!

  1. This is really amazing. Just one question remains open: Wich cyano formula were you using? Mike Ware or traditional? I found for Mike Wares it is extremly picky with paper and moreover extremly tricky in toning. So I would assume you used some kind of traditional formula, right?

    1. Thank you! Yes, I use the traditional formula, 100ml dem. water, 7.5g of ferric ammonium citrate, 3g of potassium ferricyanide. Developed in very hard water (16 dHg or hardness >250 mg/l) and oxidized with 3% hydrogen peroxide after developing and after toning with tannic acid.
