High Dynamic Range Image (HDRI) allows you to import a real lighting situation into your 3d scene. Wonderful shadows and reflections in the scene can achieve the highest level of realism in the rendering.
It helps you to dramatically speed up the lighting process and is especially usefull for automotive and product visualization.
HDRI is supported by many 3D-applications, such as 3dsmax 6, VizRender 2005, Viz 2005, Lightwave (version 6.0 and higher), Softimage|XSI, Bryce 6, Maya & Mentalray, RenderMan, Autodesk VIZ4, messiah:render (Arnold), InSight (Integra), 3ds-max & VRay, 3ds-max & Brazil r/s (Splutterfish), 3ds-max & finalRender (Cebas), Cinema4D Version 8.1, Vue5, Lightwork Render System and many more.
