The HDR image format can be used to enhance the brightness and color of digital images using a compatible software program. This file format is commonly used to correct shadows and washed out areas within a picture that has been taken with a digital camera. Adobe Photoshop and Photomatix are applications that commonly use the HDR file format for images that have been edited within the software applications.
