For my first foray into Cyanotypes I was using Arches Platine. I have some socorro and some COT 320 to try as well...

To reiterate, I was having no problem achieving a good dense dmax. To get detail in the highlights and not have acres of paper white showing in the white area of the image, I was getting blocked up shadows that were going too dark and losing detail.

I'm using the B&S Cyanotype kit. Where can I get the Mike Ware kit?
