Fluorescent flower photos look out of this world: Photographer captures glowing flower images

There are lots of beautiful flower images online, but Craig Burrows’ work is unlike any we’ve seen before. Craig utilizes a technique called UV induced fluorescence photography. This photography requires that the lens absorb all ultraviolet and infrared light and allow visible radiation to pass through to the sensor.
This kind of photography doesn’t have many specific equipment requirements beyond ensuring that only UV light passes and illuminates the subject. The biggest hurdle is ensuring that the UV LED used doesn’t fluoresce your surroundings, such as fabrics, support, backdrops, etc. Many clothing items are UV-sensitive, for example. Further, you need to work in a very dark room.
Burrows uses a Sony A77 with its translucent mirror removed and a trio of lenses: Sigma 17-50mm f/2.8, Tamron 90mm f/2.8 and Tamron 90mm f/2.5. Burrows often shoots between f/8 and f/13, which requires an ISO speed of 400 to 800 with 20-second exposures, so he told DIY Photography that he would be able to capture better low-light images with a full-frame camera.
