Re: cyano recipe

wow!
what responses!

first--Christina's response was for a 2:1 solution; I just adjusted for
a 1:1 solution (because I'm more comfortable with that)...

second--i have no doubt that high school students can measure. however,
i have 2 hours in which to do a workshop, and would prefer not making
them (20 or so) weigh out their chemicals--time simply doesn't permit
it. in any case, what's inaccurate about it? i converted everything
quite precisely, i thought...

plus, i know they have learned the chemical precision (for silver
gelatin printing & tank development) thus far in their coursework;
what's wrong with learning a little *im-*precision? i'll be giving them
references and resources to pursue, but we'll be using holgas to make 2
1/4 contact images... alternative ways of making images, true, but i
want to emphasize alternative ways of /seeing/, thus deemphasizing what
they have thus far learned... ultimately, it's up to *them* to decide
if/how they want to pursue the craft (or "art"): with technical rigour,
  by feel, some combination, etc.

we'll also be using the school's photocopier, and whatever acetate and
markers are handy. trying to operationalize Ware's concept of diaphane,
is all...
