The directional number (GN) is a key indicator of external flash performance. It expresses the maximum flash range in meters at ISO 100 and full power capacity. A higher directional number means a greater flash range and therefore the ability to illuminate more distant objects. For example, a flash with a directional number of 60 at ISO 100 will illuminate a subject at a distance of 60 metres at ISO 100. The directional number is important for judging whether the flash can adequately illuminate a scene, especially when shooting in large spaces or when soft light diffusion is needed when using diffusers or reflective surfaces.
External flash exposure control modes are the various methods by which the camera and external flash communicate to achieve the optimum exposure for the image. These modes include TTL, E-TTL, E-TTL II, I-TTL, P-TTL, HSS and D-TTL. Each of these modes offers different options for metering and adjusting flash intensity to match the lighting conditions and intended composition of the photograph.
