Will, SU1lslli1le-The lens can hardly be opened and shut quick enough to avoid over-exposure.
With LigM Clouds-From ~ to 1 second will be sufficient.
Will, Heavy Clouds-From 2 to 5 seconds will be required.
The above is calculated for the same hours as mentioned on page 12 and
for objects in the open air. For other hours and for objects in the shadow, under
porches, or under trees, no accurate directions can be given; experience only
can teach the proper exposure to give.
The Stops.-On opening the front of the camera a pivoted
disc may be seen close behind the shutter, which has three holes
of different sizes. This disc can be shifted from one side to the
other, so as to bring either hole in the cenj:er of the lens. These
holes admit light to the lens in the proportion of ~, Yz and -frr,
and they should be used as follows:
I. The Largest-For all ordinary instantaneous exposures when the sun shines.
2. The Middll17'"For instantaneous exposures when the sun-light is unusually strong and there are
no heavy shadows; such as in views on the ' seashore or on the water or in tropical or semi-
tropical climates; also for interiors (time exposures, the time of exposure required is given in
the table on pages 10 and II).
