Vertical Camera

glass, surface and platform

CAMERA, VERTICAL Cameras are used vertically for the purpose of photographing ceilings, floors, or articles laid upon a horizontal surface. Vertical fittings are ordinary tripod top, the camera being screwed to the hinged portion, which, in use, is supported vertically by a strut, as shown. The camera can be pointed upwards or downwards in a perfectly vertical position, or, if the strut con tains various holes to pass over the screw, at any angle. The late T. C. Hepworth's method (described first in 1894) allows of the camera being pointed downwards but not upwards, and it is largely used for photographing precious stones, medals, illustrations from books, etc. One advantage of such an arrangement (see figure C) is that it may be used in an ordinary room against a window, and the sub jects will probably be as well lighted as in a studio. This arrangement has been used for photographing a baby lying in a cradle. The camera is fixed at the top end of a skeleton stand ; upon the glass platform E can be placed a coloured card, paper, or other medium to serve as a back ground on which the opaque objects, flowers, etc., may be laid and photographed from above.

By employing a glass platform shadows are obviated, and this in some cases is of great advantage, while at the same time it is possible to use at any distance below the glass a back ground of any colour, which, by screening the light, can be lightened or darkened as may be required. A useful addition is a blind F to shut off all light from the upper surface of the plat form ; another is a mirror G to reflect the light upwards. By placing a negative upon the glass platform a reduced or enlarged transparency can be obtained more easily than by any other plan. Should the negative be a film it can be kept flat by placing a piece of glass over it.

obtainable commercially, but most are home made. A and B show a very simple arrange ment, the exact size of which will depend upon the camera used. The accessory takes the form of a narrow hinged table, which is screwed to the In process work, stands holding cameras vertically are frequently used when copying small objects supported on a horizontal surface and these stands are also of advantage when copying from open books.
