Create Unique and Dramatic High Dynamic Range Images In many cases the difference between the brightest and darkest areas of a scene is simply too great to capture in a single image, due to the inherent limitations of cameras. However, you can overcome those limitations through the use of high dynamic range (HDR) imaging. In this workshop from digital imaging guru Tim Grey, you’ll learn both how to capture HDR images and how to organize, assemble, and optimize them after the fact, whether you prefer to use HDR Pro, Nik HDR Efex Pro, or Photomatix.
