When photographing landscapes, it helps to create a sense of depth, in other words, make the viewer feel like they are there.
Use a wide-angle lens for a panoramic view and a small aperture of f/16 or smaller to keep the foreground and background sharp. Placing an object or person in the foreground helps give a sense of scale and emphasizes how far away the distance is.
Use a tripod if possible, as a small aperture usually requires a slower shutter speed.
