Hello. I just finished my film Wrought, which is about our relationship with decay - from rotting produce and animals to fermentation and slime moulds. There are three shots in the Fermentation chapter done using microscopic focus stacking - one of the koji fungus (used to make sake, miso, etc), one of the tempeh fungus and one of a fungus in the Penicillium genus. The focus stacking segment starts at 8:18.
You can watch the full film here, please enjoy and share widely!
