Re: spots and fish eyes

PS, the dark spots happened immediately upon coating the print, not during
development. You'll probably think I'm nuts for keeping on with the print,
but I did do 3 coats, and all three did the same thing, so it wasn't the
pigment choice, mixture, unevenness. I thought at first they'd disappear
when I developed; they didn't, but then I found them quaint (we'll see if
the faculty does) and kept doing more coats :)
