The year 2016 was a significant year, do you know why? The number of photos taken in 2016 exceeded the total amount of photos ever taken in the history of taking photos! Just let that sink in for a moment. More photos were taken in 2016 than in the whole time between 1830 (when the first official photograph was taken) and 2015, a period of 185 years!
