I have continued my use of autochromes well into the lastwinter months, and obtained some quite successful results,which have attracted some attention. Personally I like a re-flection of a blue sky in a frozen pond most. My experiencehas shown me that after September the exposure tables I useare not entirely to be trusted, and that a material addition,say of twenty-five per cent, of the time indicated, must be madeto ensure a successful result; forcing development, either bystrengthening or warming the developing solution, has not 140. A SNIPESHOOTER. George F. Holman. helped me much, as in my hands it always seemed to producea slight fog. I now come to the only novelty of the season, the Dufay-Diophichrome plates, which have practically only just comeon the market, although announced as ready for some rely on a color screen of regular lines, or rather linesof dots (of red, orange, green and blue violet) running ver-tically and horizontally, producing a very sHghtly grainedeffect, which in most cases is entirely invisible, and when itcan be perceived is absolutely unobjectionable. As a rule, theplate must be held at an angle, or under a magnifying glassto see the grain. The essential characteristic of the plates is an absolutelyhomogeneous coating without any addition of foreign elements,such as colored grains, varnishes, or fatty Inks, having theimportant advantage of imparting on the screen the greatesttransparency and luminosity possible.
