That was what I had asked, Karl. Is the loss of the iridescent effect
due to digital capture? Andy and I seem to have encountered the same
problem and believe it is. Film always captured it.

"This bug was one of the most highly iridescent I have seen. That has
always shown up well on film before. This time digital did not capture
it. Is this characteristic of digital capture"
my answer - maybe, it depends on the bug
after all, some colours we see on insects (and birds feathers) are not
actually 'colours' but a perception of colour eminating from
refraction, interference or diffraction rather than pigment

I have experience with diffraction causing colour renderings to go
askew in digital imaging where the sensors are more rigidly structured
than random grains in film, occasionally it can be overcome by
changing the distance at which the subject is photographed.
