August 19, 1916 ACCESSORY NEWS SECTION 11^ between the glass plates preparatory to inserting into. the negative holder of the enlarger. This prevents stray light from reaching the sensitive plate and fogging it during the period of exposure. With the proper attention given all of these various details and the exposure made, one would think that the most important steps in making the enlarged negative had been taken. But as a matter of fact that most important part of the whole process remains to be successfully accomplished. This is the development of the exposed negative plate, and it is th« "way in which the average enlarged negative of a fihn picture is developed which is responsible for the lack of quality noticeable in most specimens of such work. Most enlargements from film images exhibit ver} harsh highlights, a lack of correct gradation, and a veiled-over appearance quite similar to that of a film positive printed from a " duped " negative. The cause of this inferior photographic quality is found in the method of developing the enlarged negative plate. This is almost invariably attempted with a developing solution mixed the sam€ as for ordinary negative developing, whereas the light action on the plate in projecting the image from a lantern is entirely different from that occurring when a plate is exposed in a camera behind a lens. In photographing a scene or objects with a camera those parts of the subject which reflect no light make no impression upon the plate and, therefore, when the plate is developed the parts of which have not been acted upon b}' light appear as clear, transparent spots. But in exposing a plate to the film image projected by an enlarging lantern it will be found that light from the lantern is transmitted in some degree through even the densest portions of the film picture. The plate has therefore been acted upon to some extent by the light from the lantern over its entire surface. If now a rapid developer is applied to the plate, reduction will take place over the entire exposed area. There will, therefore, be no clear shadow spaces, and the plate will appear flat and veiled over with excessive density in the highlights. Use a Developer Mixed Without Carbonate The proper procedure in developing these enlarged negatives is to use a developer mixed without any carbonate. It is a simple matter to adapt one's regular negative developing formula to the requirements of this work. With the carbonate left out. the developing reagent may exhibit very poor reducing power, but this can be improved by the addition of more sulphite. A trace of bromide should be added to keep the action of the developer under control. No developing compound which requires the use of caustic alkalies or an alkaline carbonate in order to exhibit reducing power will be found suitable for the class of work under consideration. \\'ith a developer compounded as above outlined, negatives can be secured showing clear shadows, gradation equal to the original and absolute freedom from harshness or excessive density in the highlights. As the plate has (as previously noted) been subjected to a considerable amount of light action it will generally be found that development should not be carried very far. Those experienced in developing negatives may hit the density right at the first trial, while a little practice and strict adherence to the instructions given will enable any one photographically inclined to produce good enlargements from suitable film images.

GUNBY BROS., Inc., 145 West 45th Street, New York City AARON CAMPBELL OF TULLAHOMA, TENN., BUYS NEW EQUIPMENT FOR HIS THEATRE IT was a source of much gratification to the Roberts and Carter Supply Company of Nashville when they received an order from Aaron Campbell of Tullahoma, Tenn., for two of the latest improved 1916 model Motiograph machines. Mr. Campbell also will install a Mirroroid screen. Besides the above-named purchases, Mr. Campbell also bought 300 chairs and an ample supply of poster frames. These frames are manufactured by the Newman Manufacturing Company of Cincinnati, of which Messrs. Roberts and Carter are the Southern representatives. This is only another very forceful evidence that business in general is beginning to take on a rosier hue. It is but the beginning of a long line of customers for the Roberts and Carter Supply Company. The order was handled with exceeding promptness and care, and President Roberts says his slogan from now on will be : once a customer, always a customer.
