Re: Office Lighting.. HDRI, or... 2005-04-09 - By Andrew Turner

Hi Holly -
Well, first, they're different because HDRI isn't going to produce hard
shadows if you need them, so it doesn't exactly -replace- lights.
That said, I'm thinking for the office environment, it would be nice
for example if you could create your office lighting space and render
it with a spherical camera.
Now that Photoshop will be able to create HDRI images, it's sort of a
moot point as long as we can export an appropriate series of images.
For that matter, some software (Strata, Poser) uses image-based
lighting which probably doesn't do away with HDRI but satisfies the
need to a large degree; I'd be happy if Carrara could do the same.
Carrara is -really- fast when it comes to realistic lighting results!
