TRANSPARENCIES ON GLASS AND OPAL.

Photography, throughout its varied range, produces no more charming

or satisfying picture than the transparency, whether it is on glass

for the window, or on porcelain or opal for the lamp.

The beautiful and sparkling gradation of light and shade, the

variety and depth and richness of tone and color inherent in a fine

example of this picture, renders it most positively "a thing of

beauty and a joy forever,"

It is a picture made by a peculiarly simple and easy process, the

most exalted expressions of which have always commanded the popular

favor and a high price, and the working of which has, both for the

amateur and the professional photographer, the highest interest and

attractiveness. By no other method or process can the amateur

succeed in producing pictures of [p213] equal excellence, with

the same outlay of time and skill, which is a peculiarly fortunate

circumstance, as the tendency among amateurs at this time is to form

themselves into clubs and societies for the exchange of their most

beautiful and successful efforts as picture makers. And an exchange

in the form of a transparency enables the receiver to command all

other styles of pictures, through the negative that may be produced

from it.

The production of these pictures has assumed such importance already

as to have called forth a special dry plate for making

transparencies, to say nothing of the other special goods for the

same line, such as metal frames, ground, engraved and etched glass

for mounting, the beautiful borders of which greatly enhance the

beauty and elegance of the finished picture.

Transparencies are adaptable for the exhibition of every kind of

picture that can be copied; paintings, engravings, portraits,

landscapes, all become equally acceptable when skilfully finished

and properly displayed.

By this process, also, the amateur is enabled to provide himself

with slides for his magic lantern and to have the satisfaction of

exhibiting to his friends the trophies of his own skill in the use

of the camera and the developing solution.

The amateur, in order to succeed in producing high class work,

should possess himself of one of Anthony's duplicating and copying

cameras, so that he may be enabled to avail himself of both methods

of work; that is to say, by the camera and by contact printing, as

by the latter method he is restricted to the range and size of his

negatives, while by aid of the camera he is enabled to copy all

kinds of pictures to acceptable sizes, [p214] and he can make his

transparencies of equal size with his negative, or vary the size to

suit the requirements of the case.

The use of the duplicating and copying camera is fully detailed in

the article on Duplicating Negatives. By its use the amateur is

enabled to work by the wet collodion process, which has many

advantages, or by the dry plate process, using Anthony's

transparency plates or the gelatino albumen plates made in

Philadelphia. If he confines himself to contact printing, he is

restricted to the use of dry plates only.

The outfit of goods for making and finishing transparencies consists

of:

Transparency frames, common and patented, made with rings for

hanging horizontally or vertically.

Ground glasses, with borders.

Etched glasses, with borders.

Anthony's transparency plates.

Gelatino albumen plates.

Porcelain and opal plates for lamp shades, etc., etc.
