This was a trial of HDR (High Dynamic Range) panorama, made out of 25 images = 4 images around plus 1 for the Nadir, time 5 (+2, +1, Ø, -1, -2 EV) ! This is a way to get the most details in the brightest and the darkest areas !
The original 360x180 Spherical Panorama is located at http://www.360cities.net/image/living-room-hdr-brazil?override_cache=true
Click on the link above and once there, just click inside the image, then gently drag your mouse LEFT, RIGHT, UP or DOWN : the panorama will follow it ! You can also ZOOM in and out of the image !
