NO 2 EUREKA CAMERA.
5
The time required for interior exposures with the larg"!st
stop will vary from 2 seconds to 3 minutes, according to the
light outside, number of windows and color of walls and hang-
ings. Early in the morning or late in the afternoon the time
required will be even longer. With the second stop the time
required will be half more and with the smallest stop four
times the time required with the largest.
Section II1.- Time Exposures in the Open Air.
When the smallest stop is in the lens the light admitted is
so
much reduced that time exposures out of doors may be
made the same as interiors but the exposure must be much
shorter.
WITH SUNSHINE-The shutter can hardly be opened and
closed quickly enough to avoid over-exposure.
WITH LIGHT CLOUDs-From y, to I second will be suf-
ficient.
WITH
HEAVY CLOUDs-From 2 to 5 seconds will be
required.
The above is calculated for the same hours as mentioned
above and for objects in the open air. For other hours or 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.
Time exposures cannot be made while the camera is held
in the hand. Always place it upon some firm support " such as
a tripod, chair or table.
