Attached Link: HDRI render samples

You use HDRI pictures for your background sky to light your scene with.  In Vue it would be to add nice reflections to your car or wine glass.

Use Environment mapping as your Atmosphere model using the Atmosphere Editor.  Click on Effects and load your HDRI image(s).

In rela life, light comes from many sources, mostly scattered or bounced, not just a simple spot light etc

Normal pictures cannto cpature brightness, only colour, HDR captures true image brightness, so, say the SUn, it will show exaclty HOW bright the sun is.

So, you use that as a spherical image to project light otno the scene, ti also gives rflections :)
me perosnally I don't liek it os much, but I go for stylized renders, not realism.

In this pic:

I show the sneaky trick I invented: "self HDR" ;)
basically Vue can export an HDR of any scene or sky..
so I made an HDR of the normal Sky, turned atmosphere model to use Environment mapping, loaded the HDR...bingo! ;)
