Photomerge in CS3 is terrific

6 shots (in portrait format) merged without any input from me.

I'm impressed with the photomerge function too, and your shot is a good example.

Wee point though.. there is a visible mismatch just to the right of the telegraph pole left of center, running vertically through the lines and building.

This most likely happended due to the following reasons:
1) there was very small overlap between the shots
2) nodal point was not set/used
It's still a pretty good result for a fully automated tool...

I think the defect is built into the building. This is detail of single original shot.

I concur....a really great feature.....



I produced this promo calendar with very little fuss or muss....

I think the interesting area is higher and a little to the right.



What is the vertical light streak? And, how do they make those wires at the top do that? Is it a downsizing/jpg artifact?

Wires in large constant regions are often the hardest test for stitching software in images without close foreground detail. In landscapes without wires the skyline is often the tough test. If there is no close detail, just using a tripod may be enough without using a nodal mount.

A fixable bad example

Here's a bad example, 360 degree cylindrical projection, lots of detail in the bottom half, wires across sky in the top half, no nodal mount:



From left of the power pole just left of center, see poor stitching of wires at each end of the image:



This was PTgui. There were lots of control points in the bottom half of the image but none in the top where the wires are. So, add points on the wires and thin out the points at the bottom to 4 or 5 and try again:



It's not perfect, but much better.

As for the nodal correction that Nikolai mentioned, see below. There is a smeared area running vertically, just left of center at the bottom. Higher up, the brush and distant mountains are far enough away that the lack of nodal correction doesn't show and the smearing disappears:



Sorry it took so long to get an example. Control points at the wire crossing locations in the original image posted might be an easy fix.

I have just started to make panoramic photos on CS3 and I would like to know how to make the photo deeper vertically. I have tried magnifying it and when I transfer the completed photo to 'My Docs' I find upon opening it, it has gone back to its original size. I love the merging but the depth of the photo spoils it for me. If you can help me I would appreciate it.
Kind regards
