•The term "close-up" means pictures taken from i feet to (i feet from the lens. Figures above are for the hours from two hours after sunrise until two hours before sunset. To make pictures earlier or later, use the next larger diaphragm opening. The above figures applv to the temperate zone; for exposures in the tropics, see the manual. .
These rules do not apply to Kodacolor— home movies in full color. Kodacolor pictures must be made with the diaphragm set at/ 1 9, and the Kodacolor Filter in position before the lens (see folder). . „
The above table can be used with the/4.5 Long Focus Lens by substituting "/4.5 wherever '/^ appears, and Too dark wherever "f.i.8" or "/1.9" appears. For "close-ups," subjects must not be nearer than 6 feet from the/.4.5 Long Focus Lens.
Use the half speed, see page 1 1 , w ith the largest diaphragm opening in position, when the light conditions are unfavorable for making exposures at normal speed, as on tery dark and rainy days; also for exposures earlier and later than the hours given above, when an opening larger than the largest one of the.lens would be required.
