And if there were ever a piece of software that begged for a tutorial, Panorama Tools would be it.

Gui's for PC:
Ptassembler (shareware)
Ptgui (shareware)
Hugin (free - open source) (also Linux)

Mac
PtMac (shareware)

There are also several lists including a panotools list at yahoogroups.

I believe this is because the polarizing effect varies accoring to the angle of the lens and the sun; when you turn the camera to take the next shot, the angle changes. Whatever the reason, if you use a polarizer, the sky is likely to be darker in some shots than others.

I took four pictures from the porch of my house and then quickly stitched them together. I was very impressed. Since, I am getting used to digital I was impressed with how easy it was to create a good panorama with this free program. If you are interested you can find it here:

It would be nice if you could cover how to capture the images to arrive at the best final panorama. It seems that on some of my shots the colors shift from one photo to the next.

If you haven't already, check out the following sites for Pano tutorials. Perhaps Micheal can add something new to these.

One hint on taking the shots is to take a couple test shots to get a good exposure, then set the camera to manual exposure. This ensures that all the shots are exposed the same. If you don't do that the seams can be pretty obvious.

Shots with different exposures can work OK. When you output the final product, you can specify a layered PSD document with masks. You can run a levels adujstment on each layer to try to get the brightness to match. It works well sometimes. If a seam shows in an area like the sky, you can blur the mask to hide the transition.

On shots that have objects closer than infinity, I sometimes turn off the autofocus. The stitches can get messed up if the camera focuses on a closer object in one frame and a more distant object in the next.

The seams still show in the sky, which can be fixed by further blurring the layer masks.
