How I did this: A circus artist friend was performing her butoh-themed act where lays under a plastic sheet and moves around artistically so I brought my Olympus E-M1 Mk III and 12-40mm f/2.8 pro lens. And then I held a cube prism in front of the lens which does all kinds of whacky things like giving wild flares and reflecting other bits of the room into the frame somewhat randomly. ISO 3200, P mode, processed lightly in DxO PhotoLab - the DeepPRIME XD mode is a huge win for shooting high ISO on the small-ish Micro 4/3 sensor.
