Mr. Jaques Arthur, the well mown photgrapher of Detroit. lich.. did ry suddenly fit his line in tha ty on January 12th.

Mr. Arthr had been ill since Christmas hi his physicians were Kdentof s ultimaterecovery was in e client spirits, havment a pt of the day down and w i resting on a couch, to hivvife. Mrs. Clara B. whethe end came withirning.

Mr. Arthur was born in Montreal 56 years ago, the son of Alexander Arthur, a prominent merchant of that city. When a boy he made many trips abroad with his father, and being of an artistic temperament, spent much of his time visiting the art galleries of Europe.

When he was 25 years old he located in Detroit and has occupied the studio at 234 Woodward avenue for 26 years.

Mr. Arthur was considered one of the most talented and successful photographers in the United States. He was an artist first, a photographer afterwards. It cannot be said of him that he was a mere copyist. Rather, he was a creator, a designer of pictures.

While of a retiring disposition, those who knew him were his friends and the profession will keenly feel the loss of so competent and earnest a worker.

A Useful Hint

A very short but sufficiently accurate method of determining the distance that will be required to take a standing cabinet picture with any lens is given us by the Bausch & Lomb Optical Co. Simply multiply the equivalent focus of your lens by 19 and divide the result by 12, and the answer will be the distance in feet that the lens must be from the subject to make a standing cabinet. For example, if your lens has an equivalent focus of 14 inches, then multiply 14 by 19 which is 266; then divide 266 by 12 which is 22 2-12 or 22 feet 2 inches as the necessary distance required.

For the man who has his studio but who contemplates getting a new lens, if he does not already know the equivalent focus he wants in his new lens he can figure out the equivalent focus of the lens he has by reversing the above operation. Thus, focus the lens on a standing figure and get the image the standard size for a cabinet. Measure the distance to the subject. Let us say, for convenience, that you find him to be just 22 feet 2 inches. Convert this into inches, which is 266. Then divide by 19 and the result is 14, or the equivalent focus of the lens you are using. If you have room to spare, you will know that you can use a lens of more than 14 inches, but if this is all the room you have, you must get a lens of 14 inches or less, equivalent focus.
