Practical HDRI: High Dynamic Range Imaging for Photographers by Jack Howard is the latest book I have read on the subject. I haven’t touched my Photomatix software (indeed, even my camera) for some time. Reading through this book helped inspire me to get back out shooting photos, and also to see if Olympus was doing anything to help with the capture of HDR images. As it turns out, the recently released Olympus E-620 has far better support for proper image bracketing to get the exposures you need.

The book itself is fairly short - just 168 pages. But these pages are full of good information and practical examples using more than just one software package. What I like most about it is the frankness of the author when it comes to producing realistic HDR images, as opposed to some of the cartoonish extremes that have come to symbolize the genre. I much prefer a realistic image that has great depth in all ranges between the darkest and lightest sections of the image. In addition to the software examples (Photoshop CS3, Photomatix and FDRTools), the author tells you what to watch for when capturing the images, well before they see the computer.

All in all this was a very worthwhile book, with more than enough interesting bits for the novice and experienced alike. I would definitely recommend this book to anyone who is looking for more information on HDRI.

HDR (high dynamic range) images are starting to take the photography world by storm (at the time of this writing, the HDR Flickr group has over 18,000 members). If you ask a room full of people what HDR is, you get a wide range of answers, and typically they are all partly correct. Simply put however, HDR imaging is the process of creating an image that encompasses a wide range of exposure values. This allows the resultant image to be nearly all encompassing in every detail. HDR Imaging has, until very recently, been the purvey of Hollywood graphic and special effects artists. “The HDRI Handbook” by Christian Bloch helps bring this exciting arena to everyone else.
