The iPhone camera uses computational photography, applying software to every snap. This wild photo is an eery example: the subject tries on a wedding dress and each mirror shows her in a different pose. Why? Apple insider says it’s a “mistake” in the computational photography

With #RankedChoiceVoting in our presidential elections, neither major party would have to worry about 3rd-party candidates playing "spoiler." Voters would get more choices & a representative, majority winner.
