Shooting RAW offers a bigger starting color space and dynamic range in the source images, but it is not true that RAW capture is a necessity. Likewise, 16-bit files are not a necessity either. Every image in this book began its life as a series of 8-bit JPEGs.
Your camera must have Auto Exposure Bracketing (AEB) to capture source images. NOT TRUE.

A DSLR is necessary for HDR Imaging. NOT TRUE. Most current compact digital cameras have features that allow for HDR imaging—such as exposure compensation—and many current compact cameras have manual or semi-manual exposure modes.
