The human eye perceives only light in the visible spectrum, but with specially modified cameras, lenses, and visible-light blocking filters, photographers can record ultraviolet wavelengths. In this book, author David Prutchi shows 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). Prutchi takes 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
