Including art photography.
The best method for selling Landscape photography is of course through exhibitions. People generally love to put up Landscapes in their home walls. And those who are interested in art/landscapes often visit exhibitions.
The other way is to contact the art stores, who sell frames photographs to customers. Unless you are well known in the field, the photos wont sell so easily. These people often ask you to put your photos in their stores and if they sell off, you get the money and they get their commission.
The third option is to sell them to tourism websites. You may contact them directly with low resolution photos from your collection, or better still visit their office with your portfolio. If they like, you may get highly paid for giving license of your photos to them.
