The table’s top, right-hand side denotes ISO film speeds. The columns offer corresponding shutter speeds in seconds. The numbers along the top left-hand side of the table represent the focal ratios (f/stops) of various camera lenses or camera/telescope combinations. The series of diagonal lines are labeled with different stages of the lunar eclipse.
