apron, in such fashion that, when completely wound,
the apron protects the film effectually from light, and may be removed
from the winding box safely at any time. It is then lowered into the cup
of developer, the cover attached and the film left to develop for twenty
minutes. After development the film is removed for fixing.

Every step is performed in daylight and the exact time necessary for
development, in combination with the chemical formula, has been
scientifically worked out, so that all differences of exposure within
reasonable bounds are taken care of. Especial attention is called to the
new 2-1/2-inch size, for the development of 1A or 2A films.

Those who wish to develop more than one roll at a time can do so without
purchasing extra tanks complete, by securing duplicating outfits as
listed below.
