DEVELOPER: Amidol (Johnsons British) made up asfollows: Stock solution: Water 32 oz. Sulphite Soda (dry) 2 oz. Citric Acid 25 gr. For use dilute with equal amount of water to which addwhen ready to use 25 grains of Amidol to each 32 oz. of work-ing solution. Bromide of Potassium (saturated solution) 3 drops to eachoz. of working developer. The sulphite stock solution keeps, but the amidol should notbe added until ready for use and the developer discarded whenit shows loss of strength. Be sure to use the full amount of bromide because this en-ables the print to develop slowly, allows it to build up grad-ually, and brings out all there is in your negative.

As, however, negatives vary greatly it is always best tomake use of the test strips that you find in each package of thepaper, and in this way you get the exact printing time. Thevery soft negatives should be printed at quite a distance fromthe light if some contrast is desired, and the contrasty onescloser to the light. Artatone in common with all other gas-light papers removed from the light brings out more con-trast, while nearness to the light decreases contrast and, ofcourse, further away from the light the printing time is in-creased and nearness to the light it is decreased. The side ofthe paper that curls inward is the suppo
