Hello, can you please post some more information on this topic? I would like to read more.
Photoshop CS3 (and CS4) has a surprisingly capable PhotoMerge function; unfortunately, it doesn’t allow for much control over the output. Sometimes the resulting panorama or mosaic will curve upward or downward, giving it a distorted look. Other times it may leave pieces out or put them in the wrong place(s).
Usually, I’ll run my images through Photoshop first to see how it handles the job, or simply as a preview. If it doesn’t come out the way I want it, then I use PTAssembler. PTAssembler has many more projection methods to choose from as well as the ability to select matching control points within adjacent images. Read the link in the original post for an excellent summary of PTAssembler features and a description of control points.
PTAssembler is a complex program, but it has allowed me to create large or complicated panos where Photoshop or other simple methods have failed.
On a side note – and this is something I haven’t tried yet – PTAssembler also has the ability to “stack” images, as well as stitch them. By stacking, you can take, for instance, two photographs at different exposures, and blend them into one high dynamic range image. Or you can take photos of a scene at different points of focus and blend them so that the entire scene is in focus. Combine these options with stitching multiple images into a panorama or mosaic and the resulting image is something that would be impossible to capture (as far as I know) in a single photograph with any camera and lens currently available. More details on stacking and blending can be found here:
