on the over exposure, its pretty much to what i wanted to achieve. i haven't been shooting insect close-ups for a long while and i'm a little bored of the "extension tube-with-2-flashes" looks of my old macro shots, so i kinda liked the soft light and bright backgrounds in the scenes agree that the baby hopper shot is over. would you like the ORFs? I could send them to you for your evaluation.
contrast wise, the default settings will give very punchy colours. i think that's perfectly fine for a consumer camera and the OoC jpegs should work very well for most users.
