Color Photography Explained-9
In this illustration is shown some of the special equipment devised for this work. These lamps, of nearly nine thousand 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.
