One interesting plant to try may be Red Castor beans. The
leaf will be a deep red if left in dark (new shoots are a
brilliant scarlet) and the chlorophyll green yeilds a dark,
nearly black positive (ok, negative, well exposed area - you
all know what I mean).
There will be a problem with the growth zoom factor. This
means that the leaves get large, at least 8-10 inches across,
and never stop growing - they just fall off when stressed.
If you try with normal Castor beans (the boring green kind),
you will get a bleached white in the dark, umm shaded areas.
This ought to yeild a classic greenprint (prasinotype ?)
Let's see, what would the greeks say?
cyanotype : blue print
prasinotype : green print
thallotype : green (i.e. growing) plant print
chlorotype : yellow-green print (like mesquites in the spring)
phytotype : (of a) plant print
rhodinotype : red print (for Red Castor beans - of course)
