Abstract
SILVER printing-out papers are now so extensively used that a small volume like this cannot fail to be useful to a large number of those who practise photography. There is nothing particularly original in it, but a practical and successful photographer like the author cannot set down a series of instructions without giving many a useful hint. Current photographic literature and manufacturers “instructions” furnish an almost endless variety of formulæ for the treatment of printing-out papers; it will therefore be distinctly advantageous to those whose experience of such papers is not large to have a small collection of selected formulæ such as is here given. The illustrations that show the extent of over printing necessary to compensate for the loss by toning and fixing, and the kind of negative best suited for these processes, will be very welcome to the beginner. It would have been but little trouble to provide an index, the advantage of which in a book of practical instructions it is not necessary to point out.
