I've spent a little time with your fine program and it seems to work better than the others. My question is about taking 3 differently-exposed panoramic images and using a program like PhotoMatix to ensure that the highlights aren't blown out and the shadows are still visible.

Here's what I mean: http://www.hdrsoft.com/examples.html.

To do this you bracket your exposures for each image, and make 3 panoramic images - one to maintain detail in the bright areas, one for the mid tone areas, and one for the shadow areas.

The trouble is, even when you use a tripod and have your camera set to bracket each shot (each image is not moved at all), Panorama Factory doesn't stitch the 3 differently-exposed panoramic images identically, so they don't overlay properly and Photomatrix cannot work.

Is there a way to tell Panorama Factory to save the exact settings from one stitch job and apply it to the others? This way everything will line up perfectly.

Thanks!

The Panorama Factory does not provide the feature you are looking for. However, you may be able to "fake it." I'll suggest a technique that might get you the results you're looking for, but please keep in mind that this is not a supported method of using The Panorama Factory.

1. Start by stitching your initial set of images.

2. Save the stitching project using the Save project command (File menu). If, for example, you call your project "MyProject", this command will save a project file called MyProject.pfp and many image files with names like MyProject_imported_1.bmp, MyProject_warped_1.bmp, etc.

3. Close the project file or exit from The Panorama Factory.

4. Remove all of the MyProject_*.bmp files.

5. Make copies of your second set of image files and name them MyProject_import_1.bmp, MyProject_import_2.bmp, etc.

6. Reopen the project file in The Panorama Factory. It should automatically recompute the panorama using your new image files using the exact settings from the saved project.

If you are successful using this procedure, please post your results back to this forum. I'd be interested to know whether it works out for you.

I use Photomatix quite successfully, using the same image. Basically, I use Raw exposures and make a plus and a minus correction as part of my workflow -- then use Photomatix to put the HDR compression together. Since it is the same shot, there are no alignment problems. Bibble is good for automation of this, as it can process shots auto-magically and when finished, Panorama Factory can then assemble the finished HDR shots. BTW, I keep everything in 16-bit TIFF.

Photoshop CS 2, due in March, will have HDR features, and that may make automation even easier.
