How the ColorBalanceCoach target deals with the back light

This fashion image shot in Paris at The “Astre studio” (map) represented a challenge in the calculation of the light. I wanted the light hitting the front of the model only, using as background the graphical shapes of the architecture. The Camera was set on manual exposure and white balance. The disc was placed so it did not get any direct light from the outside. I took the reading of the white balance on the grey target of the ColorBalanceCoach target set it as the working white balance. Then I made the setting for exposure by shooting the 4 patches until the signature histogram of the CBC was obtained and used this setting as my exposure and did the shoot. To make sure I would blur the background, I used a large aperture (this is the smallest number on the setting of the aperture) here it is f/2.8. Not a single shot was missed.
