SWRLY - a modern take on the historic Petzval lens.


SWRLY is a modern take on the original swirly lens, the Petzval, created in 1840 by Josef Petzval. This lens design was one of the first portrait lenses and is characterized by a unique swirly bokeh effect. Many of the earliest photos (daguerreotypes, tintypes, etc.) were captured with Petzval lenses.

The Petzval lens has a sharp center region surrounded by swirly bokeh, making it fantastic for portraits. SWRLY is the first app to recreate this effect.

Daguerreotype Photos

SWRLY can really capture the daguerreotype look with the innovative negative control. Images created with the original daguerreotype process have almost a 3D quality to them as you view them at different angles. This can make them look partially inverted and negative.


Create unique photos with the swirly focus. Nothing compares to the SWRLY look to frame an amazing shot.
