COLOR photography is not new. It 

 lias been the goal of ambitious in- 

 ventors ever since scientists really 

 understood something of the nature of 

 light. Nearly all methods of making 

 colored phot()grai)hs are long and ex- 

 pensive. Though beautiful results were 

 in some cases secured, only an able 

 scientist could manipulate the apparatus, 

 time the exposures, and keep track of 

 the dozens of little things all-essential to 

 securing satisfactory results. Kven the 

 Lumiere process, widely employed as it 

 is, is han(lica|)ped 1)\- the fact that the 

 pictures must be ^•iewed through glass. 

 Most of the previous prcjcesses were of 

 the "three-color" type. That is, they 

 depended on the fact that from three 

 colors of the spectrum, red, yellow-green, 



and blue-\iolet, all other hues could be 

 made by combination. Negati\es of an 

 object were made tlirt)ugh red, yellow, 

 and blue filters, and positives therefrom 

 were colored and jiiined in various ways 

 to make a resultant colored picture. 

 Within recent >cars encouraging ex- 

 periments hav'c been made which involve 

 the use of two colors only, red and green. 

 The most recent system of color photog- 

 raphy dependant on this method is that 

 of Mr. IVrc\- 1). Brewster of New York. 



Two Plates Are Used with the Camera 



The camera emplin-ed in the Brewster 

 system anil other two-color systems 

 differs from the ordinary photograpiier's 

 mainly in that it has two plates in- 

 stead of the customary one. The one
