The lights and shadows should be caused to blend imperceptibly; this will give a harmonious effect.
Let the grain or stipple be seen in all parts suitable in fineness to the size of the head.
The refinements of negative retouching cannot be taught in books, although much has been written concerning the same.
Try to light your subject and develop your negative so as to get the utmost roundness or relief; then be careful not to destroy this modeling, but improve it by retouching, only doing so much work as to give a soft, clean-looking complexion.
Patient perseverance, close observation and trying again, will bring a certain degree of success, and while only the few can become first-class retouchers all may learn to improve their work by this great help to photography.
It was long ago said that silver printing was doomed, that in a few more years it would be among the things that were.
Other processes have been introduced, have had their little day and have passed off, some of them of much merit, and, it was supposed, possessed of every element of permanency, but they were found wanting in some very important respect, and so not being able to hold their ground they passed into the limbo of neglected things.
Silver printing, however, still maintains the field against all comers, and does so by its intrinsic merits alone. No other process has equalled it in ease of production and in beauty of finish, and it is doubtful if any process has results of greater permanence, taking the best products of the process as samples.
The one defect of the process is the possibility of its products fading, but we must not judge of a process by its poorest examples, but rather by its best; if such should be the decision, there are at this day thousands of silver prints that are co-existent with the process and remain as perfect as it is possible for anything on paper to be after such a lapse of time.
A process that is so simple and easy that it can be acquired in a few hours, is predestined to careless working, slovenly manipulation, and to endless scamping at the hands of careless workers. What wonder then if prints fade which were only half made.
Suffice it that the process, intelligently and conscientiously worked, would never suffer from such an imputation.
