How many photos have ever been taken?

/ Monday, September 19 /
"First we quantify how many analog photos humans have taken. There is a surprising dearth of direct data, but we can make some reasonable estimates. It is safe to say that at most a few million photos were snapped before the invention of the first consumer camera - Kodak Brownie in 1901[2]. From that time we can use Kodak's employment statistics as a reasonable proxy for how many photos were taken (Kodak’s dominance of those "Kodak moments" persisted for most of the 20th century). More physical photos needed more physical cameras and rolls of print[3]. Throughout this period photos became more and more mass-market - by 1960 it is estimated that 55% of photos were of babies. From 1984 onwards the Silver Institute and PMIA published estimates of how many physical photos the world was snapping each year (silver halide being an important chemical in film)[4]. Year after year these numbers grew, as more people took more photos - the 20th century was the golden age of analog photography peaking at an amazing 85 billion physical photos in 2000 -- an incredible 2,500 photos per second."
No wonder i never plan to upload photos on facebook ever again. No need to add to this giant box.
Fun facts: "Every 2 minutes today we snap as many photos as the whole of humanity took in the 1800s. In fact, ten percent of all the photos we have were taken in the past 12 months. The oldest photo of a person dates to 1838; an image of a busy Parisian street that shows an unknown man getting his shoes shined."
