extent, but nevertheless, like all of its type, it does 

 not lend itself to practical work, and will always remain 

 of more use and interest to the physicist than to the 



photographer. 



THE FUTURE OF COLOR PHOTOGRAPHY 



We have seen that the screen-plate, and especially that 

 form developed along the line which has produced the 

 autochrome and kindred plates, has thus far given 

 the most satisfactory results in color photography. 

 Nevertheless, the practicality of these methods is not 

 very pronounced, and the popular attitude toward 

 them was ably expressed by Doctor Mees in his recent 

 address before the London Society of Arts. 



"With regard to the whole use of screen-plates, 

 one is bound to feel that, interesting as they are, at 

 the present time their use must be limited. No color 

 process which cannot be printed on paper can hope 

 to appeal to the great mass of workers. . . . What 

 screen-plates need, in fact, as their complement, is a 

 printing-process such as some improved bleaching- 

 out emulsion, which could be placed on paper and on 

 which the plates could be printed." 



In these words the future of color photography is 

 clearly outlined, and before dismissing the subject it re- 

 mains to note what is being done in this direction. 



"There is a method," says Chapman Jones, "that 

 has been in the minds of those interested in these mat- 

 ters for nearly thirty years, and latterly more or less 

 worked upon by many investigators with more or less,
