[CHAPTER XI]

A BOY'S DARK-ROOM

There is no reason why an industrious boy cannot do a profitable business with a camera, when he has learned to operate it successfully, does careful and neat work, and charges a reasonable price for his pictures. The many monthly photographic competitions in the magazines should be a great help in showing where his faults lie, and when he has overcome these he should be able to make considerable money from the cash prizes offered.

An amateur should master as much of the work as possible. One of the most interesting parts is missed if you pay a professional to develop your plates, and you never know where your faults have been made in taking the pictures, by not seeing the manner in which the image appears on the negative during the development. Even though you spoil one or two plates in your first attempts at developing, your results on the whole will probably be as good as those obtained by a professional, who is very often careless with amateurs' work.

No discussion of photography has been included in this book, as a complete treatise would be too lengthy, and a condensed description impractical. There are a number of excellent publications which describe the subject in detail, making it so clear that a boy cannot help but understand the principles with a little study. Few of these books, however, dwell upon the equipment of the dark-room, and none give a fellow any ideas for the making of his apparatus, generally an important item to a boy.
