When i started with hires-panos the visiting of several spherical gigapixel-panos (360x180 dgrees) was a little bit disappointing to me (the expected "deep-zoom-feeling") - the same with my own ones i tried. Maybe reading values like 1.5 Gpixels or 3 Gpixels pushed my speculation for this feeling but i of course know that this lot of pixels distribute all over a sphere, so that it doesent leave so much for zooming to a special view.
But in most scenes you have huge areas of the picture building foreground of no interest and detailless blue heaven.
So i tried a combination like this - it combines a hires partial pano (horizontal areas) and a standard setup pano with fisheye for the spherical completion.
What do you think about it?
I´ll try to fuse it better in future...
In detail:
the hires-part shot with Canon 5D II + 85mm 1.2 L / 2 Rows á 32 pic // leading to 650-700 Mpix for the horizon (82115 pix wide)
the lowres-part shot with Canon 1Ds II + 15mm fisheye / 6 around + Z // leading to 92 Mpix spherical pano
these 2 panos then were fused in one (Photoshop); interpolating the small one to the 82115 px width
of the hires part leads to a (technical) 3.4 Gpix spherical pano with really fine details in the horizon regions of interest...
