No. 2.
| Bichromate of potash | 1 oz. |
| Distilled water | 9 oz. |
For use mix equal parts of the solution, and filter; then take a tube of moist water-color, any tint desired, and dissolve enough of it in the solution to produce the tint desired. Pin a sheet of photographic paper to a flat board, and apply the solution with a flat brush after the manner described for sensitizing paper. The paper must be sensitized by gas or lamp light.
This paper is not a printing-out paper, but is developed. Expose under the negative, lay the print for a few seconds in lukewarm water, then place it face up on a sheet of glass, and develop it with hot water, using it about 110° F.; rinse, and place for ten minutes in a bath made of
| Powdered alum | 1 oz. |
| Water | 20 oz. |
As the progress of the printing cannot be seen, it is a good idea to sensitize a strip of paper, and experiment with the printing till the time for exposure can be ascertained.
Sir Knight Kenneth Tanner, 711 First Avenue, Asbury Park, N. J., says that he has intensified several of his negatives with mercury, and that they are fading fast, and wishes to know how to preserve them. They may be restored by soaking in a solution made of Schlippe's salts, 40 gr., and water, 4 oz. Soak the negative in clear water till thoroughly wet, and then immerse in the restoring solution till the desired effect is obtained.
Lady Eudora Landers asks if the picture which she encloses in her letter belongs in any of the classes for which prizes are offered. The picture is that of a building—a log house—and therefore would not come in any of the classes. The picture is a good one, and well taken; but the camera was not exactly level, and the lines of the horizon slant. If the picture is squared by the horizon-line and trimmed, this defect will be remedied.
Sir Knight R. J. Geddes asks if by prepared photographic paper is meant salted paper. The paper, if bought unsalted, must be salted before it is used. Sir Knight Geddes will find directions for making green tones in No. 862, May 5, 1896.
Sir Knight Leonard Kebler, 142 Harrison St., East Orange, N. J., asks if his name is enrolled among the members of the Camera Club, and for the number of the Round Table which contains directions for enlarging. Sir Leonard says that in an answer to one of the queries asking about enlarging, the answer was that directions could be found in No. 801, March 5, 1895, but that he looked in this number and there was no article on photography. By referring to the number mentioned the editor finds an article on "Bromide Enlargements." This tells how to make an enlarged photograph from a small negative, which is what Sir Leonard means. Bromide paper is the sensitive paper used for such photographs, and they are called bromide enlargements. Sir Leonard is enrolled in the Camera Club.
Sir Knight Harry Chase sends a print, and asks if it would come under marines or landscapes. It would be classed with the marines. It is a good picture, the water looking like water and not like chalk or snow.
Sir Knight F. G. Clapp asks if the rule in the photographic competition saying no picture shall be sent which has been submitted in other competitions, means the Round Table competitions, or all competitions. It means any competition in which prizes are offered for best photographs. The object of our prize competition is to stimulate our club to do its best work expressly for this competition. We wish new pictures with fresh subjects, not pictures that have been sent to other competitions and placed on exhibition.
Sir Knight Gilbert Jackson asks if there is any way to remove an object from a negative which one does not want in the finished print. The objectionable part of the picture may be blocked out by painting over it, on the glass side of the negative, with Gihon's opaque, a non-actinic water-color paint.
"Edith" asks how to enlarge from a silver print. In order to enlarge from a silver print, it would be necessary to make a negative from the print, and then make a bromide enlargement from the negative according to direction given in No. 801, March 5, 1895.
Sir Knight Conant Taylor encloses a print and asks what is the matter with it. The picture was not printed deep enough, and has faded in the toning. It has the appearance of being overtoned, or toned in poor solution. In toning, when not sure that the bath is all right, test it according to directions given beginners for testing toning solutions. Take a piece of blue litmus paper and dip it into the toning solution. If it turns red the bath is too acid. Add enough of the alkali to turn the paper back to blue. Bicarbonate of soda is an alkali. In toning remove the prints from the bath before they are quite toned, as they fade in washing.
