This disclosure describes techniques to perform improved automatic white balance correction to digital images in a user’s collection. With user permission, multiple photos that depict the same subjects are found in the user’s collection in photos depicting a variety of different lighting and environments, and an automatic white balance correction is determined based on the multiple photos. The white balance correction can be automatically applied to new photos and/or older photos in a user’s collection. Such features enable automatic white balance to more accurately applied and produce higher quality photos with accurate colors.
