also carries the aiming telescope. Commercially available glass plates or cut film (4 in x 5 in) are used. Extension tubes and focusing discs can be fixed to the wide-angle or normal-angle cameras for quick change from a fixed focusing distance to other distances. Instead of the camera support, a theodolite can be placed in the tribrach for entering the control points. The Wild P 32 Terrestrial Camera has been used successfully for years. Some special features of this tried and proven instrument are its high image quality, easy operation, choice of base length and the ease of combination with the Wild T1, T16 and T2 theodolites. It is flexible, small, light and easy to use. It takes glass plates and cut film in commercially available size (6V2 cm x 9 cm) as well as roll film. Like the P31 Universal Terrestrial Camera, the P32 is corrected for the visible and near infra-red spectral range so that it can be used with panchromatic, infra-red, colour and false colour films. The principal distance of the P32 is 6.4 cm. For close-range photography, the PBA 32 Base Bar was designed to take two cameras with base lengths of 20 cm, 30 cm and 40 cm. The Wild C 120 Stereometric Camera has been used for many years in police work. It consists of a base bar, at the ends of which are mounted two cameras 120 cm apart. The identical cameras have practically distor tion-free wide-angle lenses f/8, f = 6.4 cm. The cameras take glass plates 6V2 cm x 9 cm. Corresponding to their base length, the objectives of the C 120 cameras are fix focused at 10 m. This covers the close-up range which is so important for police photography and plotting. The rigid connection between the two cameras at a fixed distance and the parallel camera axes, or the right angle they form with the base line, postulate a photographic order corresponding to the most common case in photogrammetry, the so-called normal case. The normal case involves extremely simple photography and plotting conditions. However, the fixed base means that the stereometric cameras have a limited range. The photographs are plotted either in a special plotter, used exclusi vely in terrestrial photogrammetry, or in a universal plotter which is fitted with a switch device - for switching the y and z movements - for use in aerial and terrestrial photogrammetry. Description of the plotters The Wild A 40 Wide-Angle Autograph belongs to that group of special instruments which can be used only in terrestrial photogrammetry. Its principal distance range of 54 mm - 100 mm covers the best kown stereometric and terrestrial cameras. The Wild A 40 can be fitted Q with a transformation gearbox for plotting from photographs at 30 or 60° above or below the horizontal. There are numerous advantages to architectural photogrammetry accruing form its ability to plot in the horizontal (xy-), the vertical (xz-) and the side elevation (yz-) planes. The Wild A 10 Autograph can plot at all scales from vertical normal, wide and super-wide-angle photographs as well as from terrestrial photographs. The usefulness of this type of plotter in terrestrial photogrammetry has been repeatedly proven. Depending on the camera
