Well, I started playing around with cyanotype the other day, and so far it's a lot of fun, and surprisingly simple. I do have a few questions tho; I'm sure they've been answered here at one point or another, so y'all can point me in the direction of previous posts, if that's the case, otherwise ... My first results look great (I'm amazed at the detail that the process can render), though a little underexposed - its overcast and really hard to gauge exposre. First off, about how far past "looking right" should the print get in the sun before it is washed? My first print looked fantastic, but proceeded to almost entirely wash away in the water - am I looking at maybe double that exposure? Also, about how long does the mixed sensitizer last? I coated sheets from the same stuff within a half-hour of each other, and it worked fine. Could I save it until the next day without issue? And, third, what do people think as far as toning methods go? There seem to be way more than enough of them out there - what do people find to work best?
