If,however, the sky includes ships masts,or similar things, they must of course notbe covered, but the sky blocked out on thenegative. In any case, even when thesky portion is sufficiently dense, care raustbe taken that there are no pinholes. Thesensitive paper is now taken down—itsposition on the easel and the portionprinted having been carefully marked—and some indication made as to which isthe top, so that it may be put up again incorrect position. Sometimes it is moreconvenient, instead of removing the. Fig. 440.—Arrangement for Dodging bromide paper, to cover it with a sheetof opaque white paper, upon which thenew image should be focussed. Thecloud negative is now inserted in thecarrier in place of the landscape nega-tive. This need not be the same size,although, of course, it simplifies mattersif it is, as no readjustment of theapparatus is necessary. In any casean image of the proper size must beprojected, but need not be quite sharp ;as, if so, the mechanical defects of thecloud negative will be made bromide paper is then replaced inproper position, which may be seen bythe light admitted through the ruby ororange cap. Where the light is dim itwill be found best to mark the positionby means of pins. Convenient pins forbromide work are shown bj^ Figs. 441 and442. They can be purchased of mostdealers, or an efficient substitute may bemade by inserting small needles in shortportions of a penho
