Dearborn Street Chicago Fundamentals of Light (Continued from page 1486) F d = F plus — . r On the other baud, 1) equals F plus F multiplied by r, or D = F plus V x r. An example will show how simple this rule is. Suppose one wants to reduce a picture so that a twelve-inch line becomes three inches — i.e., r = 4. If a six-inch lens is being used, d (camera extension) == 6 plus 6/4 = 6 plus 1% = ^Vz inches, and D = 6 plus 6x4 = 6 plus 24 — 30 inches. Bear two other things in mind which will help to use this formula: (1) Positions of image and object are reversible. If we were enlarging 3 inches to 12 with a 6-inch lens we should place the lens and negative 7% inches apart and the paper 30 inches apart. (2) The smaller conjugate is just r times the larger, e.g., 7^x4 = 30. This is always the case, and is useful as a check on calculation.
