428. Fix for 15 minutes, handling the prints over constantly during fixing. After fixing place the prints into a strong salt bath, 4 ounces of salt to each gallon of water; the salt will prevent blistering. After salt bath, wash thoroughly by handling the prints over separately. Sepia prints must not lie in the water and soak for any great length of time, but must be washed as quickly as possible. Twelve to fifteen changes of water, the prints being carefully handled over and over during each change, will wash them thoroughly. The brilliancy of the prints depends upon speedy and careful manipulation throughout.

429. Remarks

Remarks. Do not use any other neutralizing agent than bicarbonate of soda. Do not have your toning bath too strong. Be sure and have your bath strongly alkaline. Salt in this bath will give warm tones. Do not tone beyond the clearing of the whites, the shadows remaining very red. This should be accomplished in from three to four minutes. Further toning produces cold tones. You can better judge when prints are toned far enough in this bath by comparing with a fresh untoned print.

Place an untoned print beside the print you have toned and it will serve as an excellent guide. Do not allow prints to lag or lay in wash water, but handle them through the different waters as rapidly as possible and get them dry. The rapidity with which you can accomplish this will govern the degree of brilliancy of the results obtained.
