Ilo Drawing.

This invention relates to methods of applying, blending and setting colors, and more particularly to coloring or tinting photographs in a simple and efficient manner; but it may be used by artists generally to secure results more rapidly and perfectly l'hfllll by the methods heretofore known and usec.

According to my improved method, and by the use of the preparations hereinafter referred to and which are designed particularly for use in photography, ditliculties of properly coloring a given area, no matter how small or large, with any color or blend of colors, are wholly overcome, the efiect is most pleasing in appearance, the method itself is economical in application, and an amateur may obtain results which only professionals have hitherto been enabled to obtain.

The method may be generally described as follows:

(1) The area to be colored is intimately coated with the blending and spreading preparation (2) The colors-whether oils, crayons, pencil, or those specially prepared, are then applied roughly;

(3) A tuft of cotton in the fingers, or upon a support similar to a pencil, is moistened with the blending preparation and the colors carried to any detail of the picture;

(4) The roughly blended colors may then be held over a source of heat until the residue of the blending medium melts and further removes all lines of distortion or inequalities, resulting in a more perfect blend and smoother results than can readily be obtained mechanically.

(5) When cold, a clean tuftof cotton is gently rubbed over the entire surface, leaving a perfectly smooth, attractive finish, Without lines, blots or irregularities, and which may be either dull or highly glossy, depending upon the character of the particular blending medium selected.

These results are made possible by the use of various waxes and oils with or without gelatins or albumin, which are emulsified with sufiicient water to make a smooth paste.

The theory of the action is, that the surface emulsion of the photograph is slightly softened by the water present; the Waxes and oils, remaining soft until later dried by heat, take any character of pigment and can be smoothly and leisurely distributed, and any excess of color or misapplied color can Application filed July 10, 1924.

When highly glossy finishes are desirable, the proportion of hard waxes is increased; but when extremely dull matts are desired, the hard waxes may be omitted and the solvents increased. It is to be understood that virtually any wax and most of the gums may be used interchangeably in these formulac, and that any volatile solvents or aqueous emulsifiers may be employed without departing from the s irit and purpose of my invention. It shou d be understood that the application of heat is not essential to the performance of my process but that under certain conditions it may be desirable.

Ordinarily, my improved method may be utilized in connection with any type of color or paint now upon the market, and will be used perhaps more largely with colored pencils, whether dry or of the grease variety. However, for especially fine work selected pigments are made up in a medium substantially similar in composition to the formula given above. Thesepaints will never harden in the tubes and may be spread with the greatest ease and deliberation until the exact results desired are obtained.

Another very desirable feature of: this process is that after the coloring or tinting process has been completed on the photograph, the print remains flat and pliant in an unmounted state.

Still another very desirable feature of this process is that, after a picture has been rill colored, the coloring may be practically entirely removed by the application of the blending and spreading composition. Thus, if the painting or picture is not satisfactory, it is only necessary to apply the blending and spreading composition and wipe off or otherwise remove the coloring, leaving a surface that is ready for recoloring. The coloring may he removed regardless of the time that has elapsed since it was applied.

A further very desirable feature of my invention is that artists colors may be used to paint over and accentuate the results obtamed by the process set forth above.
