![]() ![]() There's thus going to be a real transformation of the image and not only a collage by superimposition like could have done a photo editing software like Photoshop, without using Photomerge of course. Which means that it is going to curve all of the straight horizontal lines to manage to stick them together. The big difference between specialized software and the stitching function in Photoshop, for instance, is that dedicated software can curve any horizontal line (as a rotating device would do). The columns of the central bay of the nave look very stretched. This image is typical of a rectilinear projection: all the straight lines remain straight but the edges of the panorama are stretched from a certain field of view, in general over 90°. This type of stitching makes the final picture look like a photo taken with a specialized camera with a very wide field of view like the Fuji 617 or the X Pan equipped with its 30-mm in film-based photography. In this case, the horizontal lines are not bended - tiled - but remain straight after stitching. These three pictures will be stitched using the same panorama software but two different categories of geometric transformations. Geometric transformations are detailed on the page dedicated to geometric projections but we'll see very quickly the main categories of geometries.Įither it will distort the images to keep them rectilinear, which means straight, or it will distort them to bend them. Finally, harmonize shades and/or luminosity differences in accordance with the chosen stitching software. ![]()
