There's a huge gap between the typical 3D use of HDR spheres and
the high-end use by agencies in major print campaigns. The biggest
problem is art directors are now 3D/HDR savvy and they can spot
low-res/poor work a mile away. So what was once acceptable even
12-18 months ago isn't any longer if you still want to get decent
jobs as a photographer.
What exactly is a "typical 3D use" of HDR spheres? Can someone
point me in a direction to learn more about real world applications
of HDR spheres for 3D and/or object fly-bys?
(You can see that back in 1998, these HDR panos were made with a big
ball-bearing. Both HDR and panoramas have come a long way since then.)
This is quite different from the "tonemapped" panoramic HDRs that
many VR photographers use and display. The capture can be similar,
but an HDR pano itself (used in 3D rendering) cannot be displayed or
printed out as-is. Plus, the functional requirements of both types of
panos (printed or for 3D) are widely divergent. People that know
photography for print or interactive VRs can apply some of the same
things to HDR panos for 3D lighting and rendering, but without the
complete picture technical details get oversimplified and efficiency
and quality drop like a stone. Naturally, the converse is true, which
is why I don't print many panos or do real estate virtual tours.
Also, what kind of print publications require these ultra- high-res
panos for print?
The ultra-high-res panos are used *to make images* for print. The
pano itself is seen in the reflection on an object, but the image
also serves as some of the lighting of the scene (see the above
link). These days about 10% of the car ads you see in print (yes, it
is still that low, at least in North America) are a combination of
photography and 3D imagery, so the reflections on the body of a 3D
car come from an HDR pano. You are much more likely to see the
effects of this technique used in TV ads and in the movies, but those
images are done at a much lower resolution.
