UltraViolet Photography with Hoya U340

Been working in UltraViolet photography with the Hoya U340 and an S8612 filter stack testing to see how low my two “accidental” UV sensitive lenses might go.

The Steinheil is rated to 320nm and previous test I’d done with the Lensbaby Soft Focus Optic showed it performed well with the U360, so decided to see how the Soft Focus Optic did at 340nm.

Both were shot at f5.6 as I’m finding UV needs allot of light. Does allow for limited depth of field though. A modified Yongnuo 560IV flash was used to produce the lighting.

The Stienheil does produce a well defined focus and the Lensbaby lives up to its traits of very nice soft focus effects.
