Photography is a technique, including processes and materials, that consists in fixing or reproducing over time accurate images of the real world on a photosensitive medium (silver photosensitive chemical with film or paper, digital sensor) by exposure to visible or non-visible light, such as infrared.

Initially developed for the cinema, the 35mm film format was later adopted by silver photography under the name "small format", in a practical package, the 135 cartridge containing the photosensitive film. In photography, the image size is 24 x 36 mm. For various reasons (including the use of optics developed for 24x36), digital photography has retained this format for the sensors of high-end SLR cameras.

A landscape is a natural scene that captures the beauty of its spaces, the climate, its relief and how it integrates with nature or the elements created by human intervention. It can also focus on particularities of nature, on a wide angle or a detail.
