For restraining over-exposure use the above quantity of developer,

Bromide potassium 1 oz.

"It is always advisable to use two developing trays, [p176] and
have the normal developer in one and the restrained developer in the
other. Then, by changing the plate from one tray to the other, the
character of the negative is under full control. Four to six plates
can be developed in one lot of developer.
"This developer can be used for a number of plates, and gives fine
negatives of good printing quality.
"After development, return your old developer to a stoppered bottle,
and keep for commencing development.
"The reason for doing this is as follows:
"As a rule, I give a little more time than necessary to make a
full-timed negative, and, by commencing with the old developer, give
the high lights a start of the shadows, which I can readily soften
afterwards by the use of a stronger developer at the finish, thus
obtaining the sparkling high lights so much admired in the wet
plate; and so seldom found in the average Dry Plate Pictures.
"This developer never becomes muddy, and may be used repeatedly with
fine effect.
"Always place plates in a strong solution of alum after developing
and rinsing, and before fixing. This gives brilliancy to the
negative and prevents the possibility of softening.
"In the use of the above formula it is important that the best
Chemicals be employed."
It is not necessary to make up the full amount of 2 oz. pyro at one
time.
In the foregoing two formulæ will be found all that is necessary for
making good negatives by either process.
Every box of plates that is put up for sale carries [p177] with
it the formula supposed to be best for that plate. There are other
forms of development that produce good work. The following is one of
them:
