Color Photography Explained — 9 



In this illustration is shown some of the special equip- 

 ment devised for this work. These lamps, of nearly nine thou- 

 sand candle power, were used in making a number of the pictures 

 which could be made indoors — such as those of flowers and fruits 

 which could be brought to the laboratory. It will be noted that the 

 reflecting surfaces of these lamps, instead of being white, are a 

 yellow-green, which color was used for the purpose of 

 correcting the color of the light itself, a device of 

 one of The .Society's experimenters which it 

 is believed was for the first time 

 employed in this work.
