The Photographic art-journal . doptedby Claudet. The camera is placed, within an arrange-ment of curtains, which is capable of ad-justment, so as to have any required open-ing in front of the camera. The whole ofthis screen being mounted on rollers is ea-sily moved; therefore the operator has itin his power to adjust the opening, and toshut off all adventitious radiations, thus securing the effectiveness of the rays pro-ceeding directly from the sitter, or the ob-ject to be copied. The sitter should be placed in the easiestpossible position compatible with the ar-rangement of the body as nearly as is pos-sible in a vertical plane. This is necessa-ry, as the parts which are nearest the glasssuffer a very considerable degree of distor-tion and enlargement. Of course greatsteadiness is required on the part of thesitter during the few seconds he submits tothe operation of the photographer. It isusual to support the head by a rest fasten-ed to the back of the seat, as shown in ; but where the person can maintain $. 2. steady position without this, the result isgenerally the most satisfactory, the restnot unfrequently giving an air of stiffnessto the sitter. In a great number of por-traits a dark and unnatural shade is thrownunder the eyes : this arises from the em-ployment of a top light. The lightfalling vertically produces the shadow ofthe brow over the eye, and gives a sombrecharacter to the face. This is objectiona-ble also, as being annoying to the sitter,who assumes in consequence a somewhatpainful expression. Those who have attended to the analysisof the spectrum, included in the seconddivision of our subject, have become awarethat the radiations from all colored objectsare not alike. A long description wouldnot render this so apparent as a single il- 185; The Photographic Art-Journal. 279 lustration.
