Tulip #2 - Cyanotype Tea toned

The cyanotype blue works on some subjects, but in my mind only a select few. The color and tone of this print is much more universal, and a better choice for the tulip as a subject than blue. I really like what the tea does to the print.
My two cents.

What is K2Cr3O7?

K2Cr3O7 is potassium dichromate -- commonly used as a contrast enhancer in cyanotype and many other alternate processes.

Aha! Of course. I've got to get a pocket element table. Thanks.
