Dynamic range is the range of light that can be captured in a photo, from the darkest shadows to the brightest highlight.

Digital camera sensors (or film in traditional cameras), unlike the human eye, can only capture a limited dynamic range when photographing in extreme light conditions or dark environments.

PhotoImpact's High Dynamic Range (HDR) compensates for a digital camera's limitations, and tries to resolve exposure problems that photographers frequently encounter when shooting photos that contain dramatic differences between light and shades.

It produces an optimized image by combining different copies of the same scene and uses different exposure levels to extend its perceivable tonal range. To produce such an image, multiple shots with different exposures are first combined into a High Dynamic Range (HDR) image which will record the complete tonal information combined from all the shots. This information is then used to produce a final optimized image.

High Dynamic Range also has tools that let you fix areas in your photos that are different or retain areas that you don't want to be adjusted before you combine them to produce the HDR image. This eliminates the blurred areas in the HDR image due to the differences between photos.
