There are various types of 360 panoramas which I produce as a panoramic photographer:
360 degree spherical panoramas for websites, gigapixel panoramas for print / web (rectilinear) and various other types.
I use high end digital equipment and various types of software to create these panoramas, including HDR stitching. I am also able to integrate
these panoramas into websites (html, flash, java,quicktime etc) using fullscreen, direct website integration or pop up windows, adding sound
and auto rotate as viewing options. Panoramas can also be integrated into a Virtual Tour Movie.

See more panoramic examples on my Virtual Tour website (soon under reconstuction): www.virtualtoursessex.co.uk
