I’m trying to shoot some nice product photos of cannabis for a local dispensary.

I shot some photos of a bud at F3.5-5.6 and stacked them in post, but there are still little spots between my focus points that are out of focus.

Did I choose too small of an aperture? I wanted to make sure I blurred out the background and isolated the subject to seem like it was just floating in space.

Side question: I’m also curious why macro photographers don’t just shoot in F11 and beyond instead of stacking. Is it just to get the subject isolation / bokeh?

Apologies for the newbie post. I looked at a few threads before posting and they didn’t really get me the answer i was looking for.
