Sean a long time ago I went through the motions of measuring rose petals
with an i1 to try to match the test print I had from Fuji I believe. The
vibrancy of the rose was a challenge not only for the printers but also for
the conversions and source colour spaces.
Measuring a rose petal was more challenging than I thought too. The petals
are transparent so the backing must be opaque and bright, and the i1 very
flat. When the instrument is flat the colour is not the same as the way we
perceive the rounded and specular reflections of the surface. No idea
scientifically what phenomena it might be but what my eye sees wasn't coming
out on any devices as expected.
I suppose now with the high gamut printers and screens this exercise would
be easier. Maybe even fun as I have a HP Dream Color monitor and Z3200 where
both have a lot of potential for high gamut colour and previewing those
colours too.
