Under the Sea Iris…
I love when I can multi purpose photo accessories for different genres of photography. I originally got Fractal Filters for cosplay photography and was just starting to test them out at conventions when the pandemic hit. Fractal Filters are different shape prisms attached to what looks like silver (not brass) knuckles, look them up they are pretty cool! Imagine my surprise when one suggestion to create blur in flower photography was using prisms. With a little bit of practice the Fractal Filters created an Under the Sea Iris effect.
