Rosemary Beetle, Chrysolina americana

Nice photos Graham. Which settings did you use for your Powershot and what was the depth and number of your slices? Thanks,

Eric

First image: 11 images, each @ 1 sec, ISO 100

Second image: 15 images, each @ 1.6 secs, ISO 100

Third image: 12 images, each @ 1 sec, ISO 100

I did not measure the slice depth: The method was to use a fixed arbitrary division marked on the focus knob, after first visually confirming that the increment used gave overlapping focus for successive increments.

Scale was by photographing a ruler.
