The white balance option in camera settings will control the camera's ability to handle different lighting conditions. While under ideal conditions the "Sunny" white balance should always be used, it's important to change this setting to reflect the conditions at the site you're trying to fly.
Some examples of white balance settings

Why is it important to get it right?
White balance is based on color temperature, a characteristic of visible light. Essentially, this is about how color is perceived based on the type of light present. For example, a green shirt may look like different colors depending on whether you are outside on a sunny day, under fluorescent lights, or in low lighting.
While human eyes and brains can process how lighting conditions impact colors, digital cameras cannot do this without help.
By setting your white balance to match the light conditions on sight, you are providing that help. You are telling the camera that "this object is white", which allows the camera to adjust all other colors accordingly.
Effect on your data
Setting the white balance to match the conditions of the day, will not negatively affect the accuracy of your final model and data. What would be affected is the colors in the images and model. So if you forget to set it correctly, don't sweat it!
