The Flash Power iPhone App is a camera flash calculator. Based on guide numbers provided by the manufacture of a flash unit, the calculator will determine either the maximum flash distance for a given aperture or the necessary aperture for a desired subject distance. The guide numbers given out by a flash vendor are normally based on a rating for the flash using an ISO of 100 and the distance in meters. The calculator will perform the conversion to use other ISO stops. The distance given will automatically be converted from meters to feet in the calculator.Flash Power iPhone App does not contain any ads or in-app purchases.
