Text Appearing Before Image:
a,with just as little Pyro as possible. When the image appears,or rather after all the principal features in it are visible, theplate, without any washing, is placed in a pail of cold v/ater;the pail is covered up; the light in the dark-room turned down,and it is left there to develop itself for a half-hour—perhapsan hour—for there is no harm done if left even longer. Thena normal Pyro-soda developer is made up, the plate put intoit, and in a few minutes it gains the density desired. The negative thus secured, if the solutions have been fresh(an important point), has even detail, brought out with thegradations beautifully rendered, of a quality eminently suit-able for enlarging. Most Pyro-soda formulae give an equal quantity of soda andsulphite, but if a slightly larger quantity of sulphite is useda clearer negative is the result, which cuts down the exposurein enlarging considerably. And another point, Ortho plateswere not so largely used at the time the negative was secured. 220

They are almost universally used nowadays, and a plate thathas been found eminently suitable for this class of work is anon-filter Ortho plate of considerable speed—a slow plate isundesirable. Owing to the increased exposure necessary, themovement of the water and the craft incorporated in the com-position the use of a filter is out of the question.
