With Artificial Lighting:
• Use Presets with Fine-Tuning. If Auto White Balance doesn’t give good results, try using different presets, or fine-tuning the WB in the right direction.
•** Custom WB.** If you are close to your subject, you can easily set custom WB. If you are far away, try using a lens with a longer focal length to isolate a neutral area in the distant scene as a custom WB sample.
With Mixed Lighting:
• Remove Secondary Sources. Try closing blinds or curtains or changing position and shooting from another direction.
• Set WB for Dominant Source.
• Set WB to Average. If the lighting from the different source is even, you can set WB to average the effects of the combined lighting.
• Use Flash. If your flash is strong enough, you can use it to overpower artificial lighting.
