THE FERROTYPE.<br />
means <strong>to</strong> secure good expressions, all of which<br />
having been done, the camera is placed in proper<br />
cond<strong>it</strong>ion, <strong>and</strong> the ground glass in the rear ad-<br />
justed. <strong>The</strong> correct focus is next <strong>to</strong> be secured.<br />
To this end a cloth, which is kept for the pur-<br />
pose, is thrown over the camera <strong>and</strong> the head,<br />
shutting out all the light from the object-glass,<br />
enabling us <strong>to</strong> see the image of the s<strong>it</strong>ter, in<br />
an inverted pos<strong>it</strong>ion, on the glass. <strong>The</strong> focus is<br />
adjusted by moving the lens w<strong>it</strong>h the right h<strong>and</strong><br />
from or <strong>to</strong>ward the object-glass, until the correct<br />
focus is found, which is the place of most perfect<br />
defin<strong>it</strong>ion.<br />
Plenty of time should be devoted <strong>to</strong> the ad-<br />
justment of the focus. <strong>The</strong> opera<strong>to</strong>r should<br />
always <strong>make</strong> a perfect certainty of securing a good<br />
focus. If <strong>it</strong> is found that parts of the figure<br />
project <strong>to</strong>o far forward, or otherwise, <strong>to</strong> include<br />
them in the range of the instrument, the pos<strong>it</strong>ion<br />
should be changed so as <strong>to</strong> bring all parts of the<br />
figure in<strong>to</strong> such a pos<strong>it</strong>ion (consistent w<strong>it</strong>h ease<br />
<strong>and</strong> grace) as <strong>to</strong> secure a distinct image, every<br />
part of which shall be equally sharp in defin<strong>it</strong>ion<br />
on the ground glass. <strong>The</strong> plate-holder may now<br />
be pushed in<strong>to</strong> pos<strong>it</strong>ion, or, as in some boxes, the<br />
ground glass may be removed <strong>and</strong> the plate-<br />
holder placed in the pos<strong>it</strong>ion <strong>it</strong> had occupied,<br />
the lens being first covered w<strong>it</strong>h a cap provided<br />
w<strong>it</strong>h each lens for that purpose, or by the cloth<br />
used in focusing. After the plate-holder is in<br />
pos<strong>it</strong>ion, the s<strong>it</strong>ter is directed <strong>to</strong> look <strong>to</strong>ward
