1. set your shutter speed to about 1/200 or 1/250 (depends on your external flash sync speed)
2. Set your ISO to lowest possible
3. choose aperture around f/5.6 to f/8
4. set your external flash gun at your preferred lighting angle (you need to play with the flash power yourself)
5. Happy Shooting!!!
