High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios.
Luminance HDR/QtPfsGui is a free (open-source) HDR-workflow software for Linux, Windows and Mac OS X based around the pfstools package; LDR tonemapping is a free (open-source) tonemapper for low dynamic range images (a.k.a. "pseudo-HDR") Atlas is a free (open-source) port of the pfstmo tone mapping operators to Adobe After Effects
Current generation gaming systems are able to render 3D graphics using floating-point frame buffers, in order to produce HDR images. To produce the bloom effect, the linear HDRR image in the frame buffer is convolved with a convolution kernel in a post-processing step, before converting to RGB space. The convolution step usually requires the ...

Another approach (more suited to hardware acceleration) is to render the view from ¯ by rasterizing black geometry against a white background and taking the (cosine-weighted) average of rasterized fragments. This approach is an example of a "gathering" or "inside-out" approach, whereas other algorithms (such as depth-map ambient occlusion ...
The program uses a shader script model inspired by the RenderMan Shading Language, allowing different shading styles to be written as a script that's interpreted at the render time.
Luminance HDR, formerly Qtpfsgui, is graphics software used for the creation and manipulation of high-dynamic-range images. Released under the terms of the GPL, it is available for Linux, Windows and Mac OS X (Intel only). Luminance HDR supports several High Dynamic Range (HDR) as well as Low Dynamic Range (LDR) file formats.
Radiance defined an image format for storing HDR images, now described as RGBE image format.Since it was the first (and for a long time the only) HDR image format, this format is supported by many other [which?] software packages.
