One popular category in landscape photography is panoramas. Panorama photography is a technique used to get a wider scene in one picture. Some will call it wide format photography.
The principle is you take several photos after each other of a scene and stitch the photos together in a dedicated software. The challenging part is to get the photographs right in camera.
The post processing is quite simple if you have good photos to work with. A great panorama photo printed and hung on a wall is simply eye catching.
