Anyone have any recommendations for a program that can handle these? I want to both take photographs of overlapping images and merge them together into a single image, and take multiple (faint) photographs of a single object and merge them into a single (brighter) image. In my ideal world, this would be a single piece of software, rather than two separate ones, just to keep the number of tools I use for handling photographs to a minimum (I use Photoshop for detailed hands-on editing, so a plug-in would work pretty well). While I'm listing ideal characteristics, it would be nice if it could handle the operations reasonably well entirely on its own, but also allow me to adjust settings and handle aspects of the merger manually if I want to take the trouble or if the automatic settings aren't perfect. It would also be nice if it ran under Windows. I'm willing to pay for it, though if someone knows of a freeware piece of software that can handle this kind of operation, that would be even better. Any recommendations?
