How to balance Flash and ambient light using an incident light?
To resolve this, you need to dial down the output of the flash by five stops (f4 > f5.6 > f8 > f11 > f16 > f19>. Set the flash to 1/32 power which is five stops below full power. It is always good to take another test reading and adjust the distance of the flash to subject to compensate for a half stop variance (to f/19).
What’s the difference between ambient light and flash?
This continuous lighting we will now call “Ambient” or “Available” light. It is the light that is available to you without having to use an additional light source such as a flash. With this ambient light, as a photographer, you can then expose for the ambient (available) light only.
