Hi Jani, Lens distortion can be corrected mathematically. Even chromatic aberration, to some extent. Of course, if you start with a good lens, like the EF 100mm f/2.8 USM Macro, the task is a lot simpler. And if you use the same lens, the same factors can be used for all the images in a mosaic. Perspective changes can either be deliberate (e.g. orthographic), or minimized by rotating the camera about the lens nodal point. Pictures taken in such a manner can be remapped into different projection, including cylindrical (e.g. swing lens), spherical, and rectilinear.
