R. B. T. asks if there is any remedy for a negative which is under-developed after it is fixed. It can be intensified--in other words, redeveloped. See directions for intensifying in No. 824, August 13, 1895. If you have not this number, it will be mailed you from this office on receipt of 5c. FREDERICK S. COLLINS asks if solio toning solution can be used for toning albumen and aristo prints; and what makes a thin negative. The solio toning-bath can be used for aristo, but is not suitable for albumen paper. A thin negative may be the result of over-exposure, under-exposure, or under-development. Over-exposure makes the negative a uniform color and lacking in contrast. Under-exposure gives strong high lights and no detail in the shadows. Under-development gives good detail, but the negative is too weak to make a good print. Such a negative can be redeveloped or intensified. See answer given to R. B. T. L. K. asks where to get the magazine _American Amateur Photographer_. The address of the publishers is 239-241 Fifth Avenue, New York city. The price of the magazine is $1 per year. HENRY READ wishes a remedy for keeping the film from looking as if it were crackled; also how to make dry-plates. The tray should be rocked during the development of the film. The crackled appearance will then be avoided. Do not try to make dry-plates. The operation is too long, and the plates can be bought much cheaper than they can be made at home, besides being always reliable.
