Practical HDRI

How to Capture the Beauty of Infrared Imagery

HIGH dynamic range imaging (HDRI) "As digital sensors attain progressively higher resolutions, and thereby successively smaller pixel sizes, the one quality of an image which does not benefit is its dynamic range. This is particularly apparent in compact cameras with resolutions near 8 megapixels, as these are more susceptible than ever to blown highlights or noisy shadow detail. Further, some scenes simply contain a greater brightness range than can be captured by current digital cameras -- of any type. " (Excerpted from this tutorial: The Dynamic Range Dilemma, cambridgeincolour.com)

In image processing, computer graphics, and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows. (WE)

In the newest book from Rocky Nook�"Practical HDRI" -- well-known expert Jack Howard leads you on an exploration into the exciting new frontier of High Dynamic Range Imaging. HDRI is a method to digitally capture, store, and edit the full luminosity range of a scene in ways that are just not possible with a single captured image.

Jack�s illustrated text is easy to understand as he takes you from the initial image capture and into the digital darkroom. Here is where you will learn to use this cutting edge photographic technique to achieve spectacular results.

Covered are the most popular and effective HDR programs such as Adobe Photoshop CS3, FDRTools, Dynamic Photo HDR, Photomatix Pro, and more.

Topics include:
- Illustrated step-by-step tutorials
- Basic and advanced workflows
- Post-production optimization for both web and print
- File management
- Advice on cameras and software
- A wealth of HDR images, ranging from subtle to surreal
- Real-world shooting tips from Jack�s personal experiences as both a creative photographer and photojournalist.

HDR imaging for the photographer can be challenging and frustrating for the uninitiated, as it involves both field and computer expertise. However, Jack Howard explains this complex subject matter in a practical way that will not intimidate the beginner nor bore the experienced photographer. The emphasis in "Practical HDRI" is on the creative process and how to make it work for you�rather than the science behind it.

Jack Howard is Online Technology Editor of PopPhoto.com/Popular Photography & Imaging where he tests and reviews cameras, lenses, software and other camera gadgets.
