Understanding White Balance Settings
White balance settings are included in each of our preset packs. No camera can get the white balance accurate 100% every time, so use the white balance settings as a guide to a starting point. We recommend learning white balance in-depth, so you can dial-in skin tone with your eye. Understanding white balance takes practice and time to learn, but it is a vital skill to learn for creating beautiful photos, faster.
