Text Appearing Before Image:
Figure 2. this, is to take a piece of paper and pass it around the barrelof your lens—this will give you the length from C. to D. The flare of the shade, i.e. from A. to B. must be sufficientto clear the angle of view included by your lens, which on anordinary rectilinear or anastigmat will make the length about 152
Text Appearing After Image:
CO 3 inches longer than that from C. to D. This however hadbetter be determined by experiment. The glove fasteners can be sewed on by hand, but yourshoemaker or glove store will put them on by machine in acouple of seconds, and do it much neater. The *cut out at F. is only necessary when the diaphragmmarkings are engraved on the barrel of the lens, and this canbe scooped out after the shade is finished. The inside must be well blackened, so that no reflections canreach the lens—this is important. You now have a shade that will go into your pocketbook,or coat pocket; lie flat; take up practically no space; and willlast you your photographic lifetime. It takes less time to make it than what I have consumed indescribing it, and I stand ready to guarantee that your workwill be improved many hundred per cent by its use, even whenthe sun is at your back.
