Thanx, it was very very beautiful place and time indeed.
I don't use a fish-eye lens to make any of my photo's. To make panorama's the lens I use is "AF-S Nikkor 16-35mm 4G ED", normally at 16mm/F4.
Image above in example were originally 4 seperate photo's. I merge those images within Photoshop CS5 (has an good buildin and easy-to-use photomerge function). When the panorama is finished I cut away unnecessary stuff and continue with some basic post-editing untill finished.
note: total images is 4 times 3 because of HDR, so 12 seperate photo's for above panorama
