In most instances, it is impossible for the camera to capture full dynamic range (the total range of light in a scene, from very dark to very light) accurately in a single photo. In other words, today’s digital camera can’t properly expose everything at the same time in scenes with even moderate contrast ratios. This results in two main problems (which sometimes happen together in the same photo):
Blown highlights – When the exposure is raised to make sure the foreground or subject is properly exposed, brighter ar eas of the scene suffer. They “blow out” and turn white because they have very little or no usable data in them.
Lost detail in the shadows – Conversely, when bright areas of a scene are pro tected (by lowering exposure), there is not enough light to register details on the camera’s sensor in dark areas of the scene. These turn to shadow and black ness.
The solution is Photomatix Essentials, a standalone program for HDR (High Dynamic Range) image creation and processing. By importing enough photos (typically 3, separated by 2 EV steps) of the same scene under different exposures (such Photos are often called bracketed photos, in reference to the Automatic Exposure Bracketing function available on many DSLR cameras) into the program, it is possible to merge the photos into a single HDR image, rescuing details from shadows and keeping highlights from blowing out.
