Camera white balance failure and overexposure due to presence of ambient light
Because the spectral output of the flash is known, the white balance and the exposure control of the camera
work in optimal way with the flash in total blackness. This is why some of the pictures may fail (i.e. images
get a bit yellow or reddish, or greenish or bluish, depending on the ambient light characteristics, as well as
overexposed or underexposed).
If the flash works correctly in dark conditions, there is no need to change the flash module.
