"That last statement really stood out when I read it - if "the human eye

i was thinking of such things as ir aerial plant/soil fertility
photography, where the color of the image carries a lot of
information about the fields thus surveyed.

yes and no.  it's also a way of registering optical-spectrum data,
when you want to correlate spectral data in a 3-dimensional form.

ultimately, the objective is presentation to the human eye, but there
can be steps the human eye is not capable of seeing.
