My pics were always yellow. Even with the flash, it was hard to get a nice pic under HID. Especially sodium.
So, I did a little testing and reading and I came up with a very simple solution.
My camera is a cheapo 10 year old digital and it has this setting so the chances of your camera having it are probably high.
It's called white balance. Bring up your cameras menu and look for "White Balance". Under that menu is 4 choices, Daylight, Overcast, Tungsten Light and Florescent Light.
Set it for Tungsten and let me know how it works for you.
Below are 5 pics. The first is at auto mode. The second is Florescent mode without a flash. The third is Florescent mode with a flash. The fourth is Tungsten mode without a flash and the last (and best) is tungsten mode with the flash.
Just FYI to help you take better pictures of your ladies.
