Hey, thanks a lot Geoff. I'm still learning and right now I guess a lot. I think the key to understanding though is that there are two exposures, the flash exposure and the ambient light exposure. The flash exposure is made up of the ISO, aperture and flash power. The ambient light exposure is made up of ISO, shutter speed and aperture. So to change the background light only, then alter the shutter speed. To change the subject light only, change the flash power.
