i'm having some problems balancing the white balance of my flash and the ambient light when shooting night portaits, outdoors in singapore.
when i use flash white balance, the sky turns a red colour. when i correct wb for ambient using a grey card, my subjects (who are lit by flash) has a very cool skin tone.
does anyone face the same problems? and how do i get around this issue. will warming up the flash using CTO gel help?
