DOSCH HDRI: USA City Backplates contains 15 backplate sets or sceneries. Each set depicts one scene through backplate images, plus the corresponding HDRI for lighting of objects - and their reflections.
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, 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.
