From PMANewsline.com:
The opportunity in the photo industry continues to grow, as more and more pictures are taken. Blogger Benedict Evans reports, in 1999, the peak of the film-camera industry, consumers took around 80 billion photos, according to Kodak. We’re taking far more now, but how many more? At least 2 trillion, maybe double that, maybe more.
According to Evans, no-one can know this exactly, but there are some points of triangulation:
Evans said, just rounding WhatsApp and Snapchat up to 1 billion a day to account for growth in the last year and presuming no growth at Facebook this year gets us to a figure of 1.5 trillion photos shared this year. Growth in usage in the year across these could easily take that to over 2 trillion. That presumes no duplication between these three networks, which is not certain but might not be enormous.

Note: To put that number into perspective, if two trillion one-dollar bills were place on top of each other, the stack would be 135,732 miles tall, or a little over halfway to the moon. [Sean]
