"High dynamic range imaging (HDR) is an important technology for photographers. It is a collection of techniques that allow a wider dynamic range of luminances between the lightest and darkest areas of an image.

"The human eye can adapt to luminances from 0.000,000,1 cd/m² up to 1,000,000 cd/m², and can cope with a luminance range of 1:1000. However, computer displays only offer a contrast of approximately 300:1. This means that the luminance offered by a computer monitor falls significantly short to what the human eye can actually process.

"HDR software allows computer graphics to offer the full real world levels of illumination, with darker darks and brighter lights, while at the same time increasing the amount of lighting detail displayed in all areas of the image. While standard image formats utilizes 8, 16 or 24 bits with applied gamma and color space, the HDR image format extends the bit depth up to 96 bit in a linear color space. Additionally, HDR images can be photometrically correct"
