Through combination of the background image and an HDR-image of the object that is to be depicted at that exact location, absolutely realistic overall results are possible.

Background Backplate + 3D model of a product + HDRI for Reflections & Illumination = Perfect Result

The backplates are provided in a resolution of 7216 x 5412 pixel - and the highest resolution of the Spherical Map HDRIs is 13000 x 6500 pixel.

Radiosity - and therefore the use of HDRIs is directly supported in many 3D-applications like Lightwave (version 6.0 and higher), Softimage|XSI, Maya & Mentalray, Pixar RenderMan, Bryce 6, Autodesk VIZ, messiah:render (Arnold), InSight (Integra), 3ds-max & VRay, 3ds-max & Brazil r/s (Splutterfish), 3ds-max & finalRender (Cebas), Cinema4D Version 8.1 and more. For further HDRI-rendering tools options the documentation of the used 3D-program should be consulted.

And each HDR image is provided in the industry standard .HDR. So they are useable in most rendering applications.
