I would have liked to have known that photography was going to become a world where mediocre images were considered great, where people with no skill could take pictures without understanding anything about photography. It would have saved me 40 years of learning a skill that is slowly being taken over by amateurs with phones.
We hear this lament a LOT. There's quite a bit of truth in it though. When photos were made ONLY on film, pictures were less-common, more-expensive to make, and far,far,far, FAR fewer people actually made photographs. Today, many editors and writers think they can just snap a few frames with a P&S digital, or a low-end Canon Rebel, or even a phone camera, and can run the images through software, and get "decent" images.
Of course, this is the way things actually work in the world. At one time, only the VERY rich knew how to read and write. Then literacy became widespread. At one time, only the very wealthiest people had "home movies", and the remainder of the population had only a handful of B&W snapshots; the common folk had ZERO motion images of themselves or their children or activities, vacations, weddings, etc.
I think the things that made photography "easier" were Super-8 cartridge loading movie cameras; the flashcube; the Instamatic 126 cartridge loading concept and the Kodak Instamatic; decent color print film; the proliferation of FAST 1- to 4-hour minilab develop and print; then the development of the video camera from a huge video recorder + camera monster and its morphing/evolving into a small,self-contained cam-corder, specifically something like the Sony Hi-8 format camcorders which were small, like the very small Sony TR-5 camcorder at $899 back in 1990. By the time motion video had been miniaturized and refined down to the Hi-8 format camcordesr...digital imaging had truly "arrived"...and still photography was about to be revolutionized.
It's been quite a shift; a weekend fishing trip used to mean a roll of film, or maybe two rolls of 36; today, it can be 1,000 to 2,000 digital "frames"
