How many digital photos will be taken in 2017? It’s predicted there will be 7.5 billion people in the world in 2017, and about 5 billion of them will have a mobile phone. Let’s say roughly 80% of those phones have a built-in camera: around 4 billion people. And let’s say they take 10 photos per day – that’s 3,650 photos per year, per person. That adds up to more than 14 trillion photos annually (14,600,000,000,000).
Much more conservatively, if only one billion people have cameras or phones, and take less than 3 photos per day/1,000 pictures per year, that’s still 1 trillion photos captured every year.
