Digital Camera Dilema

We have some experience in digital photography. We use an Olympus Camedia digital
camera C-3030 zoom to make pictures of our (small) butterfly wings. Afterwards we
measure some morphological characters on these images with an image analysing
system (Optimas-software). If you want to measure colours or grey values, you have
to standardize your light conditions.
I'm afraid it is not easy to make reliable pictures in the field, just try and see
... .

With kind regards,
