ENLARGING CAMERAS.
An enlarging camera is practically corn posed of three parts connected by an extra length of bellows. The term is generally applied to apparatus intended for use with daylight ; although occasion ally a camera of this descrip tion may be adapted for use with artificial light. Fig. 66 shows a typical enlarging camera arranged on a suitable bench with tilting movement, in order that it may be pointed up in the direction of the light. A camera on this principle may be of any desired size, some of those used by professional workers being extremely large. At the end nearest the light is provided a frame having car riers of different sizes to take the negative. The lens is fit ted in the central portion of the apparatus, and may be adjusted to any distance, while the plate or bromide paper is contained in a large dark-slide at the rear end. Some de scriptions of enlarging cameras are also adapted for copying, the length of bellows making them very suitable for the pose. There are now
many convenient terns of portable larging cameras, ing into a very small compass. Some of these, of which Fig. 67 is an excellent ple, permit of focussing and justment for different sizes of largement. Others are of " fixed focus," and do not require sing, but are in consequence ted to a definite area of ment. For this, however, they make up in greater compactness and portability. An example of these is given in Figs. 64 and 65 on p. 39, the latter showing the apparatus closed. Tho negative is placed in the small box-like car rier at the top, and the bromide paper in a removable frame at the bottom, the exposure being given by turning a handle outside which raises a hinged flap in front of the lens.
