In my experience I have shot 27 exposures using my 85 mm Canon lens and stitched those into a single image using Ptgui stitching software. This effectively increased the 12.8 MP of a single exposure from the 5D to a 345 MP image. This does require a special tripod head that allows the lens to be rotated on the axis of it's entrance pupil. This is done to avoid paralax.
This is not the limit of what can be accomplished with either the hardware or of the software. Others have made images of gigapixel dimensions (one billion pixels).
As I said at the outset, this may not be of interest to those whose primary emphasis is on slide show production...it is undoubtedly the way to improve print image quality to the level of large format cameras and beyond.
All for your information.
Now i've got my Canon A640 that problem is a thing of the past. There's a feature on there for stitching images together. After taking the first shot, the image is kept on the left of the screen so i can set up the second shot before taking it. Then it's just a case of adding them together in Photoshop and 'Bob's your Uncle'.
Makes you wonder where digital cameras will go next
Frequently, when my wide lens just isn't wide enough, I'll just shoot several images & stitch them together. I never use a special tripod head. In fact, I often don't even use a tripod. Last year in China, I hand-held 9 shots in 10 seconds of a large city plaza, full of moving people. It stitched together beautifully.
Overlap 1/3 and keep the horizon straight. Shooting verticals has worked best for me. If possible, "average" the overall exposure & shoot manual. A really wide shot can have a sizeable exposure range & automatic can cause different exposures for the various shots, which are noticeable in the stitched image. Of course, some images are better/easier to work with than others . . . a rather close up panorama of the Air Force Academy Chapel completely confused all of the panorama stitchers that I tried. None could decide which of the roof peaks to match up.
My file sizes are not nearly as large as Don's, but panoramas (large or small) can definitely add a new dimension to your photography . . . and it's a lot of fun too.
quote: What is Image Composite Editor?
Microsoft Image Composite Editor is an advanced panoramic image stitcher. The application takes a set of overlapping photographs of a scene shot from a single camera location and creates a high-resolution panorama incorporating all the source images at full resolution. The stitched panorama can be saved in a wide variety of formats, from common formats like JPEG and TIFF to multi-resolution tiled formats like HD View and Silverlight Deep Zoom.
State-of-the-art stitching algorithms automaticaly place source images and determine panorama type
Advanced orientation adjustment view allows planar, cylindrical, and spherical projections
Support for different types of camera motion
Excellent exposure blending using Microsoft Research fast Poisson algorithm
Automatic cropping to maximum image area
No image size limitation - stitch gigapixel panoramas
Native support for 64-bit operating systems such as 64-bit Vista
Output in a wide variety of image formats:
Silverlight Deep Zoom
TIFF, JPEG, PNG, and more un-quote"

I love the info you send in on photography. Thanks.It's always very helpful information. I just checked the forum this morning and, as fate would have it, was out practicing panoramic shots of the Hudson River yesterday. I was planning on stitching them together using Photoshop CS4. I'm assuming the workflow is to stich them together in the RAW format and then tweak for exposure, lighting and color. Right? Is the increase in mp the reason you prefer Ptgui?
Thanks again for sharing your expertise,
The cropping is not done so you can see it ... that is, you see where the cropping borders (that you can adjust if you want) but you don't see a (final) cropped image.
For quick and dirty this thing looks really good! I haven't had time to play a lot with it but thought I'd try it on a set of 9 images and see what came about. I used JPGs as the source images since they were already available.
I didn't try images (yet) the require more than one row of stitching ... curious as to whether it'll handle that as well as a single row. (their forum seems to indicate that multiple rows work).
Interesting anyway ... another option. I haven't compared to the Autopano Pro output yet either. Still, it looks pretty good ... and for cheap!
Autopano pro will detect panoramics in a folder if you ask it too and will stitch the ones it finds for you. It'll iron out the color and exposure differences between images it's stitching, it'll try to remove ghost image (say someone moves location in the set of images you take ... it'll remove the ghost image), and it'll handle fish-eye lenses. It can create an hdr image from under and over stopped images. And it will stitch HDR images together. It'll analyze images to see if they'll fit into the pano ... they don't have to be level to do that (yep, the images can even be tilted!) (it stitches spatially and dynamically). It supports stitching jpg, tiff (8/16-bit), png (8/16-bit), many types of RAW images. And, like PTGui, will export to a layered PSD file for touchups. It'll import the hdr images
PTGui will stitch the images you tell it to stitch, including HDR images. Can export a multiplayered PSD file, as well as to JPG, 8 and 16-bit tiff or png files. It imports those JPG, tiff, and png only as well as HDR and exr. Doesn't appear that it can create an HDR file tho if it's not already an HDR source.
It appears that, for the most part, Autopano Pro does a bit more than PTGui for fewer $s. Both however are excellent choices!

Detecting & stitching "panorama parts" from within a folder is an amazing feature. That feature alone is bekoning me to buy. I shoot a ton of panoramas, simply because I've been so pleased with the relatively few that I have stitched. Most of them end up not getting stitched. When shooting I try to remember to "shoot my feet" before/after panoramas for the sole purpose of marking the panoramas & later rename the parts pan01, pan02, etc.
I can envision a workflow (especially after an extended photo trip) of letting the software run overnight just searching for the panoramas. Do you know if the input filenames are incorporated in the output filenames? Output from the trial version cannot be saved, but maybe I could do a hands on test on a small group of files.
For me it would be great if there was cheap/free software that would search the panoramas, even if it didn't stitch or if the output wasn't "up to snuff".
