Table 5-3: Equivalent Shutter Speed/Aperture combinations for Example 2

V.If you are using film that is faster than 100 ISO (200 ISO, 400 ISO, etc.), you must use the shutter speeds above the one next to your desired f-stop. Each time the speed of the film is doubled (100 to 200, 200 to 400, etc), you must use one shutter speed faster.

For example, assume that you want to use f/18 and the Extinction Meter indicates that you should use a speed of 5 (1/5th of a second). If the film speed is faster than 100 ISO, you should use the speeds above 5 according to the chart below:
