This technology saves the 3D-designer from elaborate manual definition of multiple light-sources and also from lengthy experimenting with color choice and light-volume. The HDRIs also contain the information whether there is a direct light-source (e.g. sun, spot light) with defined shadows - or a cloudy sky/neon lights with diffuse light and "soft" shadows.

But also the color spectrum of the real scene (environment) has great effect on the virtual, rendered object or scene. The color of things (e.g. trees, gras, forest ground) in the surroundings for instance will impact the appearance of the rendered 3D-model ... likewise will the fiery red-tone of a sunset cloud create a realistic mood of such an event in reality.

71 HDR-Images of various natural scenes are provided in the most widely used formats:

Light-Probe (Angular Map)

Spherical Map (Latitude-Longitude)

Vertical-Cross

Horizontal-Cross

Radiosity - and therefore the use of HDRIs is directly supported in many 3D-applications like 3dsmax 6, VizRender 2005, Viz 2005, Lightwave (version 6.0 and higher), Softimage
XSI, Maya & Mentalray, Pixar RenderMan, Autodesk VIZ4, messiah:render (Arnold), Bryce 6, 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.

High-resolution HDRIs:

The HDRIs of this collection (V1 content) are provided in the following resolutions - and are therefore also perfectly suited for background use.

Light-Probe - 2048x2048 Pixel

Light-Probe Small - 512x512 Pixel

Spherical Map - 2048x1024 Pixel

Vertical Cross - 2048x1536 Pixel

Horizontal Cross - 1536x2048 Pixel

Format: .hdr (RADIANCE Image Format)

New in version 2:

15 additional HDRIs in a very high resolution of 10,000 x 5,000 pixel have been added. Please view the PDF for a detailed resolution list of the various formats.
