David Prutchi, Ph.D. SWUV SBUV converters

I just posted a whitepaper containing complete construction details for two DIY imagers for the shortwave ultraviolet band. These UV converters can be used for RUVIS and Solar-Blind imaging applications.

iPhone-based DOLPi Polarimetric Camera Developed by Paul Wallace

iPhone DOLPi Camera developed by Paul Wallace

Reader Paul Wallace contacted me to tell me about the DOLPi electro-optic polarization camera that he built for his iPhone. His ingenious solution makes use of the iPhone’s flashlight to calibrate and synchronize the control of the polarization analyzer (hacked from a welder’s mask as described in the DOLPi whitepaper).

New Book on Ultraviolet Photography

Posted on July 2, 2016 by David Prutchi Posted in Uncategorized

My new book “Exploring Ultraviolet Photography: Bee Vision, Forensic Imaging, and Other Near Ultraviolet Adventures with Your DSLR” is now available on Amazon for pre-order.

In this book, I will show you how to select equipment that allows you to capture otherworldly UV images. You’ll learn how to use filters that block visible light and prevent infrared light leaks and will discover how supplementing or overpowering sunlight with artificial UV light sources can help you create stronger images. You’ll also learn postprocessing techniques designed to enhance your UV photographs.

There is much to discover about the world as seen by bees, birds, and butterflies (and other creatures). I will take you into the wild to capture UV images that show how flowers advertise their nectar with beautiful markings to attract pollinating insects and birds. You’ll also discover how butterflies that look dull in visible light burst with intricate, iridescent patterns in UV.

Finally, you’ll learn about the scientific, medical, and forensic uses of ultraviolet photography.

From start to finish, this book will educate, inspire photographic creativity, and foster a better understanding of the UV world.
