How can I align a set of images, all taken in the same direction (not a panorama)?
This can be done using PTGui; it can be used for (e.g.) accurately aligning a set of images for manual HDR creation, for making a time lapse movie, or for extending depth of field by merging images taken at different focusing distance. It requires a special workflow though. By default, PTGui expects that a project contains overlapping source images, taken from the same viewpoint, but in different directions. The perspective changes that occur when the camera is rotated allow PTGui to accurately calculate the focal length (or field of view) of the lens. When all images are taken in the same direction, this information is missing and PTGui may end up optimizing the lens parameters to wrong values. This can result in a very small field of view, or introduce barrel distortion. If the images are taken in one direction, they can be aligned in the following way: • Load the source images in PTGui. • Switch to Advanced mode by pressing the Advanced button in the Project Assistant. • Go to Lens
