Figure  8-14.—Proportional  scale. 4. Draw a broken vertical line at a right angle from it to the diagonal line as before. Extend the diagonal line to meet the broken line. 5. Complete the rectangle and measure the space. This is the area your photograph will occupy when it is enlarged. The Proportional Scale Method Perhaps  the  most  common  way  of  scaling  is  the proportional   scale   method.   The   proportional   scale (fig.  8-14)  has  a  movable  inner  disk  with  a  window mounted  on  an  outer  disk.  Both  disks  have  unit graduations from 1 to 100. Any unit of measurement can be used with the proportional scale. To use the scale, you need to know three of the four measurements involved in scaling. You must know the cropped width, cropped depth and reproduction width (or  the  reproduction  depth  if  you  are  establishing  a reproduction  width. Use  your  proportional  scale  to  determine  the reproduction  depth  in  the  following  example: PHOTOGRAPH   DIMENSIONS:   The  cropped width is 18 picas and the cropped depth is 4 inches. It will be used in a one-column, 13.5 -pica-wide space. STEP 1: Align the cropped width (18 picas) on the inner disk, with the reproduction width (13.5 picas) on the outer disk. STEP 2: Find the cropped depth (4 inches) on the inner disk and read the reproduction depth opposite it on the outer disk. The reproduction depth is 3 inches. 8 - 15
