Have you ever taken the ‘perfect’ selfie, only to post it on Insty and get a total of three likes? Well, finally science is being put to good use! A study has analysed millions of selfies from around the world and found a formula to maximise your selfie game. A Stanford University researcher plugged 2 million selfies into a machine that looks at every single pixel and categorised them into ‘good’ or ‘bad’ images dependent on the amount of likes they received.
