As I would prefer the ISO to be lower, I have kept the above settings except that I have the ISO fixed at 100. I now find that before I press the shutter the settings in the viewfinder tell me the shot is going to be very underexposed. Do I go ahead and take the shot and will the flash power increase to take account of the lower ISO of 100, resulting in a well-exposed picture I have a lot of experience of outdoor photography, but flash seems to be a whole new ball-game altogether. Any thoughts on the matter would be appreciated.
