So flash (unless it's some fancy photographer setup with diffusers and stuff) and direct sunlight on clear day ain't brilliant. If you have a specific light source more than light all around then keep your camera near your light source so we don't see all the harsh shadows.
Try not to mix light sources with different hues/color temperature. If you have sunlight on one side and a ligthbulb on the other tan half the model will be blue and half will be yellow.
Then get a copy of photoshop from somewhere. Under "Image" you find "Auto Tone" and "Auto Color". They're fucking magic.
