What went wrong - Another Tay Bridge disaster

[Bynx]

Thanks for the info Alan. Didnt mean to post in your post but it seemed appropriate since it is all about panorama and those reading probably know more about it than I do.

Only too delighted, Bynx, feel free. I wish I could remember a quick answer to your question. I'll let you know if I find out, but let's hope someone else provides the definitive answer first (brain ticks slowly these days).

Ok, so here's my 2 cents on the matter!

Basically as you turn your camera (a rotation) different parts of the lens are closer and further from the object by very small amounts. As a consequence, the bridge is moving away from some parts of the lens and toward it in others.

the way i have been able to do it a bit better is by doing a translation rather than a rotation. In other words, rather than turning the head of the tripod, i physically move the tripod to the left or right. it eliminates the distortion rather nicely!
