I am using this for more several years now. Even though all my workflow happens on Macintosh computers these days I’ve kept this tool in my toolbox: Microsoft Image Composite Editor.
Now after along while with the 1.0 version Microsoft Research decided to release a new version of the free tool with even more features and a new streamlined user interface. This is so much better than before.
“Image Composite Editor (ICE) is an advanced panoramic image stitcher created by the Microsoft Research Computational Photography Group. Given a set of overlapping photographs of a scene shot from a single camera location, the app creates a high-resolution panorama that seamlessly combines the original images. ICE can also create a panorama from a panning video, including stop-motion action overlaid on the background. Finished panoramas can be shared with friends and viewed in 3D by uploading them to the Photosynth web site. Panoramas can also be saved in a wide variety of image formats, including JPEG, TIFF, and Photoshop’s PSD/PSB format, as well as the multiresolution tiled format used by HD View and Deep Zoom.”
There was the Digital Image Suite and several other tools like Hugin and Cool360 which I used over the last years to create panoramic images. Now there’s a new tool available in 32 and 64 bit (for really really huge images!) from Microsoft Research. It’s free at this point and if you’re on Windows it’s definitely worth the try.
“Microsoft Image Composite Editor is an advanced panoramic image stitcher. You shoot a set of overlapping photographs of a scene from a single location, and Image Composite Editor creates a high-resolution panorama incorporating all your images at full resolution. Then save your stitched panorama 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.”
