The American annual of photography . hotographs of those Loved long sinceand lost awhile, has not had occasion to lament the fadingof some valued portrait, and, from a merely utilitarian point ofview, what folly it is to spend either time or money in workingup, either in color or monochrome, on a base which will prob-ably become yellow and fade, destroying the values of lightand shade obtained, and making what was a pleasing portraitonly grotesque. For the credit of photography it is to be regretted that thepubHc do not always realize the risky nature of a worked upsilver print, and insist that when they pay for artistic finish-ing, they shall have d- reasonable certainty that the result shallbe permanent. This may be secured by employing carbon prints; the bestmakers of tissue being scrupulously careful to use only per-manent pigments in the manufacture of their products, and touse papers that are least liable to change tone with age, forall papers, even the best, are subject to a slight but negligiblechange of tone. 82. RUDOLF DUHRKOOP. The choice of a process is often decided by the question nicost, although econom}^ should be rather a wise expenditureof money than merely a question of cheapness. In this re-spect, carbon is about on a par with silver printing, because,although the cost of tissue and transfer may be slightly abovethat of silver paper, there is no further incidental expensefor toning solutions to be considered. Space forbids my entering in detail on methods of manipu-lation, but I strongly advise beginners to follow exactly theinstructions issued by the makers of carbon tissues, and notto deviate from them until they have succeeded in producinggood results; for, although all makers of photographic mate-rials are human and therefore fallible, they may be trusted intheir own interest to issue instructions which, if followed,leave the least liability to failures.
