Swirly Bokeh — AI Bokeh & Depth filter

The swirly bokeh of a century-old Petzval lens: background blur that rotates around the subject like water circling a drain. Photographers hunt vintage brass lenses at auctions for this exact optical flaw. This filter recreates the swirl — sharp center, spinning periphery — and with it the dreamlike, slightly haunted quality that made those lenses legendary. The most distinctive bokeh in the set; nobody scrolls past a swirl without slowing down.
