You can hardly see it as you coat it, but the blue is there OK and you can give it full exposure. Dilute solutions seem to need rather less exposure than full-strength ones. lol, Henry -- your msg. came JUST after I had coated the paper and was planning on a much reduced exposure time, which is all at this point in my learning curve that I knew to do -- So, next iteration of cyanotype stage variation belongs to you!
