Ever get deep in a rut and try to get out real quick? It's an easy matter to drift in, but usually a hard job to get out. It is natural for us to do things the easiest way, but the easiest way is not always the best. The line of least resistance always leads into a rut.
I knew a printer at one time, who made it a point to go over a paper manual every so often just to see if there were any points that had slipped his memory, and, if there were any changes in formula or manipulation, he was quick to find them and profit by their use.
It has often been said that the photographer does not read the manuals and instruction sheets which are put out by the manufacturers, but we know this is not generally true. If there is a misleading error in an instruction sheet and it is overlooked by the manufacturer, he receives enough inquiries to prove beyond a reason of doubt that the instructions are read carefully by a great majority of consumers.
The manuals of instruction and trade journals are of the same importance to the photographer that the medical magazines of authority are to the physician. It is the means of keeping in touch with the experimental departments of the manufacturers and securing the things that are new at first hand. It does not pay to let your competitor set the pace for you to follow. It is much better to lead in the new things and let the other fellow follow you. The public will have more confidence in the man who keeps abreast of the times, for the public appreciates progres-siveness.
A set of rules formulated for the betterment of last year's work will not suffice for the year to come. It was said of a certain city, that it had 29.000 ordinances, while the Kingdom of Heaven had only ten, but that was nothing against the city in question. It was a progressive city, and probably grew so fast that new ordinances were constantly needed to keep up with the rapid change in conditions. The same will apply to photography.
Keep out of the rut by keeping continually after something better. A prominent photographer was once asked what he considered his best piece of work, and the prompt reply was, "I have not made it yet." Never be satisfied with what you have done, but continually strive to do better and you will never get into a rut.
With the Artura-Method Sepia and Hypo-Alum Toning Baths, a convenient method of heating the solutions and keeping them at an even temperature without having the tray hotter than its contents, is very essential.
By applying the heat directly to the tray containing the toning bath, it will become so hot that prints settling to the bottom will tone unevenly and the surface of the prints will be changed, causing glossy spots. The Eastman Toning Bath Heater obviates these difficulties. The comfort of the one doing the toning should also be taken into consideration.
Back view of Toning: Bath Heater showing; two compartments.
Heater is constructed on the principle of a double boiler. The lower compartment is a shell of galvanized iron, made to set on an ordinary work table. A gas plate is placed in the center, the connecting tube, being run through the lower opening at the back side. The ventilators are made only in one side and the ends so that no heat will be thrown out on the side where one stands to watch the toning.
Front view, showing toning tray resting in water compartment.
The water compartment or upper tray, which is also of galvanized iron, fits snugly into this shield, resting on its upper edge. It is made to hold the regular stock size 16 x 20 steel enameled tray, the rim of which will rest on the edges of the water compartment.
When the toning tray is so placed in the water compartment, enough water is poured into the compartment through the lip on the side to almost fill same. The amount of water in the tray can readily he seen in the lip at the side and more can he added as evaporation takes place, without disturbing the toning tray.
With this heater the toning solution can be kept at a more even temperature and tones secured with more certainty and comfort than in any other way.
The price of the Eastman Toning Bath Heater is $5.00. This does not include the enameled toning tray, thermometer or a gas plate.
