I've tried chroma keying out just the blue and that looked horrendously bad.
I've added the haze to all the tatooine shots so that they are all consistent.
note, some people may find it is too dark or too blue or whatever on your screen. all I can say is, you need to calibrate your screens. mine is and this is being done based off that calibration.
