Hello David,
Are the barges really moored on a curve or is this the result of a fisheye lens?
Whatever, I do like the effect, the curve seems to arrange the boats in a lovely, fan-like pattern.
I live quite near Skipton which is famous for these barges. They used to have an annual barge festival which was a great occasion for photography and sense of fun.
My warm regards,
Bev :-)

No not a fish eye lens.My camera has a zoom lens but when making a panorama from several shots (5 in this case) it is best to set focus that approximates to about 50mm in 35 mm terms.Wide angle even on the very best prime lenses including those with anamorphic elements introduces distortion
This pano was taken on the corner of the canal basin which which contributes to the curved look.Panoramas often look curved because they show that which it impossible for the eye to see. Stand on a long straight road and look straight across at that which is in front and it does not look distorted.Now look left and the sides of the road will appear to converge into the distance which is the perspective effect.The same on the right.And so when left,centre and right are combined the result seems to be a curve.This effect can be prevented by taking shot after shot and moving sideways several yards and then each shot will be taken looking directly across thus eliminating the converging lines of the perspective effect.I hope this makes some sort of sense. With best regards, David.
