This is a trial of 5 bracketted shots, to get a properly lit background !
The original 360x180 Spherical Panorama is located at http://www.viewat.org/?i=en&id_aut=2489&id_pn=25290&sec=pn
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 !
