The silverware shown on the same page is made with a vertical camera, the silver being treated in the same way as cut glass to kill reflections. The table cover over a black ground gives a rather pleasing effect - though most manufacturers would probably prefer a plain background.

Cut glass looks well on either a black or white ground if it has been properly prepared. It is usually photographed flat, the dishes being placed upside down to show the cutting. In our white ground illustration on page 9 the negative has been blocked, but good results may also be secured on a neutral ground without blocking. The cut glass is usually coated by spraying on some such substance as aluminum or gold bronze or a coating of ordinary stove polish which may be brushed lightly when dry.

On page 11 we show a result secured with no preparation of the subject whatever. This is a highly polished mahogany piano and, naturally, the plate used was a panchromatic. An ordinary plate could not have produced such a result from the finished article and if the piano had been photographed "in the white," as commercial men term the unfinished wood, the result would not have given a correct idea of the finished article.

Following this is a comparison of results with an ordinary plate and a panchromatic. Every effort was made to secure the best possible result with the ordinary plate, three negatives being made and the best result selected. Only one negative was made on a panchromatic plate with the result shown. The subject is an inlaid mahogany box.

Stoves are photographed quite simply by going over the nickel parts with a bit of putty to kill the reflections, painting the balance of metal parts.

Many subjects require no preparation whatever other than blocking out the background, but in many cases an article appears to the best advantage if it is shown in two positions in the same picture, as shown by our illustration on page 21. It is often an advantage to have some article in a picture by which the size of other objects may be judged. The knife answers this purpose in the picture of the cantaloupe, and in many cases a foot rule is used to give an idea of the size of small objects.

We might go into detail regarding the treatment of various subjects in commercial work, but the information would be of little real value. Conditions are rarely the same in two cases. Selection of proper material is more important. Orthochromatic plates or films are almost always essential, the latter taking the place of a non-halation plate as well. Color filters often further improve results, while for certain subjects failure stares one straight in the face unless a panchromatic plate is used.We trust these illustrations may be interesting to all of our readers and helpful to those who have not had a broad experience in commercial work. It is a line in which there is much competition, but the man who can photograph anything and do it well can, as a rule, ask a good fair price and be sure of getting it.
