By a dark roQnJ is meant one that is wholly dark-not a ray
of light in it. Such a room can easily be secured at night
almost anywhere . The reason a dark room is required is that
the film is extremely sen sitive to white light, either day-
light or lamplight, and would be spoiled zf exp osed to it even
for a fr action of a second.
Having provided such a room or
closet, where, when the door is closed,
no
ray of light can be seen:
1. Set up on the table or shelf the
Orange Candle Lamp, and light it as
directed in the circular which comes in
the box in which the lamp is enclosed.

orange light which will not injure the
film unless it is held close to it. Set the
lamp on the table at least eighteen
inches from and with the side toward
the operator. The Lamp.
I!. Unroll the black paper and detach the film from it.
