As will be seen by our illustration, the Eastman Mask Chart, which is printed on opaque mask paper, makes it possible for the photographer to cut a mask of any size within the dimensions of 8 x 10 inches, without having to make any measurements whatever and with the assurance that when the mask is cut, it will not only be absolutely accurate, but in the exact center of the paper.

The perpendicular and horizontal lines on the chart are numbered each way from the center, the numbered lines being one-half inch apart. If you wish a mask with an opening 3x6 inches, you have only to cut along the perpendicular lines numbered 3, which are one and one-half inches from the center line, and along the horizontal lines numbered 6, which are three inches above and below the center line, and your mask will have an opening exactly 3x6 inches in the center of the 8 x 10 mask.

The lines between the numbers are one-eighth of an inch apart, and by following these lines, openings may be cut with dimensions in fractions of inches. Eastman Mask Charts are sold in 8 x 10 size only, the price being 15 cents for a package of one dozen. They will be found a great convenience in simplifying mask cutting and insuring the opening being perfectly true. Your dealer has them.

How much different and better modern photography is than was the photography of a few years ago.

Tilings have changed wonderfully - so have you, and it's time you were visiting the photographer.
