ISO
The ISO setting on your camera can extend the range of your flash just as it contributes to faster shutter speed and f/stop combinations in normal outdoor shooting. For example, if your camera is set to ISO 100 and the exposure combination for your subject happens to be 1/60th @ f/11, when you change the ISO to 200, your exposure combination changes as well and you could use either 1/125th @ f/11 or 1/60th @ f/16th. You can use this to extend the range of your flash unit also.The content you are trying to access is only available to members. Sorry.
