[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Hi Kip, following is my method for successful fill flash: FILL FLASH *The shutter speed is set to the maximum allowed by the synch capability of the camera, or lower (depending on light level requirements). *The lens opening is set for the highlight. *The flash is set for the amount of desired fill in the shadow areas, or contrast between highlight and shadow. For example: A side-lighted or back-lighted scene requires an exposure of 1/100 (1/125) sec at f:8 The top synch speed for the camera is 1/50 sec. The camera setting will be 1/50 sec at f:11.0 If the desired ratio between highlight and shadow is 1:2, the flash is set to f:5.6; for a ratio of 1:4 the setting would be f:4.0 Depending on the flash, the setting can be made for manual or automatic mode. Since it is a group that you will be photographing, you might have time to bracket in order to cover all possibilities.
