The operator's own camera and lens may be used, and a makeshift arrangement consisting of black silesia running on iron rods, and fitting on to the lens at one end, and bearing a focussing screen and a dark slide to hold the sensitive surface at the other. We
have seen earlier that we may use the actual light of the sky itself, and this is shown also in fig. 54, where the camera is presented to the sky. If we are using a darkened room, then the camera must be tilted in the same manner; this may have some advan-tages, which in our opinion are out-weighed by the extremely awkward manner in which the camera has to be sloped, the sensitive surface, of course, having to be parallel with the negative. We come back, therefore, to the method of using tne reflected skylight, and fig. 55 will show us how to ar-range the whole apparatus. We have de-scribed the method of blocking-out ' the window.
