Architectural photography

Architectural photography is concerned with the photographic image of architecture. In the design and planning phase, this includes the photography of models for the representation of the proposed development. In the execution phase of the development process of a building on the site is documented. Upon completion, the building is documented in its current state. Architecture Photography has a close relationship to the genre of still life photography, industrial photography and landscape photography.

Methods

The perspective of architectural photography is traditionally derived from the drawing. The central perspective chosen in that regard relates mainly from the standpoint of a human observer, the moves in the vicinity of the building or an elevated position ( bird's eye ).

The implementation of the vision of the plan drawing in the photographic image leads to several problems:

• Conventional lenses have optical error in the sense pincushion and barrel-shaped distortion. Although such pictures can be quite attractive (eg when fisheye lens ), these are usually cheaper than undesirable effect or in the photogrammetric work ( for the measurement of works) disturbing. Distortion "free" lenses are difficult to establish, especially in the wide angle range for SLR cameras, as they are due, not symmetrically constructed by the free space of the oscillating mirror, but retrofokussierend. These optical errors can be corrected in the analog enlargement process either by an exact calculation of the optics or by means of electronic image processing.
• When the film plane is not parallel to the vertical and / or horizontal lines of the building, these " rush " and / or " escape ". For vertical lines this creates the impression that the building tilts backwards. Usual small-and medium-format cameras with fixed lenses must be kept perfectly horizontal to avoid these effects. This limits the design possibilities. Remedy Faltenbalgkammeras with which the Scheimpflug rule applies, shift lenses, the adjustment of the large-format camera and professional camera or the equalization with the electronic image processing.
• In many cases, a sharp image of the entire object or surfaces that are not parallel to the film plane, is required. Ways of doing this are sufficient stopping down and the adjustment of tilt lenses, large-format camera and professional camera.
• Often a detailed and grain- poor imaging is desired. These large film formats are required.

In addition to the artistic and documentary illustration of buildings the use of photographic methods in the measurement of importance at. In particular, a spatial measurement is possible by stereoscopic photographs.
