Many professionals use the off-camera flash for many lighting tasks. The attached image was taken in bright sunlight with an AD200 about 15 feet from the camera and about 3 feet to the right of the camera. I was about 10 meters away from the group. Flash was at FULL output, shutter speed 180 sec/F4.0/ISO 100. Lens 24-105 at 45mm. Uses the GODOX remote transmitter on the camera.
