HANDBOOK OF KINE M4 TOGRAPH Y. 151 nothing of appreciating largely enhanced returns for small additional outlay, will insist on his projector being fitted with a lens by one of the well-known lens makers, such as Busch or Dallmeyer. The illustration (fig. 119, page 150) is of a Dallmeyer Kinematograph Pro- jection Lens, which may be had in any focus desired from two inch to six inch. Only those who have worked with high-class projection lenses can realise the difference they make to the clearness of the picture, as also their effect in making possible greater economy of current consumption for a given brilliancy of throw. FIG. 120. BEARD'S LIGHT CUT-OFF. FIG. 121. KINETO LIGHT CUT-OFF. Figures 120 and 121 show respectively a Beard and a Kineto light cut-off. These cut-offs are of the hand operated type, being therefore auxiliary to the automatic light cut-off fitted to most modern pro- jectors. Hand cut-offs are fitted on the lantern cone, or directly before the slide carrier. In this way they act as curtain cut-offs when projecting title and announcement slides. Both the makes of cut-off figured are practically identical in action.
