Fate has dictated that I was never meant to succeed at a few things, including photography or complex mathematics:eek::D.
Like this POS:

Apart from the sky not stitching correctly on the RHS, why is there so much distortion in the foreground? What would you have done differently?

Looks to me like you stood in one spot and rotated around to get the shot, so the road doesn't look straight.
If measured the distance between you and the road at you'd get close in the middle and far away at either end.
If you took a shot and then walked along the road a bit, and taken another shot...
Or not include horizontal lines in the foreground.:D

To correctly take a panorama you need to rotate the camera around the nodal point of the lens. Rather than type it all out here, check this site Nodal Point (http://archive.bigben.id.au/tutorials/360/photo/nodal.html)

Hmm ok.
Nice photo Derek.
The link doesn't really explain how to find the nodal point.

Did you look at this link Nodal Point (http://archive.bigben.id.au/tutorials/360/photo/nodal.html):confused:
The issue is to overcome the parallax when you rotate the camera. To do this you must rotate around the nodal point and not the focal plan of the camera. Usually the focal plan is in line with the tripod mount of the camera - usually designated on the body by a circle with a line through it. This link graphically demonstrates the difference in the two scenarios.
Also this only applies to a camera that you are viewing the image through the lens. As this applies to most digital cameras (DSLR viewfinder or LCD screen) it can be achieved. The RRS site shows the type of equipment and its use. If you do a google you will also find sites showing how to make your own home made pano rail.

i like your picture, just tell everyone it was taken with a fish eye ;).....and say you forgot to rotate the polarizer hence the funny patch of blue :D

A lot of my panoramas that I sell are stitched images. A few points:
. Use a standard to telephoto lens, not wide angle. Standard lens is 50mm for 35mm SLR film camera, & about 35mm lens for a 2/3rds digital camera.
. Set exposure on manual not auto to avoid varied exposure as you pan.
. As mentioned before rotate on the nodal point to be absolutely correct. Nodal points can be obtained from the tech data of lenses. Having said that I do a lot of my panoramas hand held, usually because where I go I don't want to be lugging a tripod.
. To make life easy and get fantastic results use Photoshop CS3. The photostich component is probably the best improvement of CS3 . Thats why you can hand hold and pan with ease.
. By turning the camera vertically you will get more in the image.
Happy shooting. :D
