I am doing some work for a colleague, shooting live scorpions. They sit still long enough to perform a z-series of about 10 shots. However, when I look at the stack at 100%, the fine bristles look a little fuzzy. At first I thought it might be a problem with circular diffraction, since I was shooting at high f stops, but I still see it at f11.
Anyone out there with suggestions? Thanks
Responding to air movement ??
try shooting them at f8. and what is circular diffraction?
Perhaps it would help to post the image(s).
If you are focus-stacking, you should be using the optimum aperture for your particular lens. This is usually 2-stops down from wide-open.
Which lens (mfr & focal length), and which aperture did you try?
P.S. - The proper term is small or large aperture, not high or low f/stop.
My aperture of choice for focus stacking is f/8. If you pay attention to focal plane, you should be able to get a decent stack with ten images. It's hard to say without seeing a posted image with "store original" checked.

Small aperture diffraction & circular diffraction are the same phenomenon:
