The Protune feature is not available on HERO3 White Edition. That being said, what I can suggest is that you use a 3rd party application (e.g. Lightroom, Premiere, etc.) if you need to adjust the picture settings of your contents.
For videos, you can check this list of editing applications that work well with GoPro files as shared by a Hub member.
Hopefully this helps!
