the
picture-image does not print out during exposure, but requires to be
developed, as in negative-making. The preparation of the paper is beyond
the skill and equipment of the average photographer, but it may be readily
obtained from dealers in photographic supplies.

What are the practical advantages of bromide paper? In the first place, it
renders the photographer independent of daylight and weather as far as
making prints is concerned. It has excellent "keeping" qualities, _i.e._,
it does not spoil or deteriorate as readily as other printing papers, even
when stored without special care or precaution. Its manipulation is
extremely simple, and closely resembles the development of a negative. It
does not require a special sort of negative, but is adapted to give good
prints from negatives widely different in quality. It is obtainable in any
desired size, and with a great variety of surfaces, from extreme gloss to
that of rough drawing paper. It offers great latitude in exposure and
development, and yields, even in the hands of the novice, a greater
percentage of good prints than any other printing paper in the market. It
offers a range of tone from deepest black to the most delicate of
platinotype grays, which may be modified to give a fair variety of color
effects where this is desirable. It affords a simple means of making
enlargements without the necessity of an enlarged negative. It gives us a
ready means of producing many prints in a very short time, or, if desired,
we may make a proof or enlargement from the negative fresh from the
washing tray. And, finally, if we do our work faithfully and well, it will
give us permanent prints.

The bromide papers available in this country at present are confined to
those of the Eastman Kodak Company, the Defender Photo Supply Company and
J. L. Lewis, the last handling English papers only. Better papers could
not be desired. Broadly speaking, all bromide papers are made in a few
well-defined varieties; in considering the manipulation of the papers made
by a single firm, therefore, we practically cover all the papers in the
market. As a matter of convenience, then, we will glance over the
different varieties of bromide paper available, as represented by the
Eastman papers, with the understanding that what is said of any one
variety is generally applicable to papers of the same sort put out by
other manufacturers.

First we have the _Standard_ or ordinary bromide paper made f
