Back in the days before cell phone cameras, before digital SLRs, before digital cameras of any sort even existed... you needed film to take any sort of photos.
You know, film cameras! You had to load a roll of 35mm film into the camera, with 24-36 shots on it, no viewfinder, no do overs. Film was expensive, developing that film was also expensive, and you even had to wait an entire hour to get your photos back (or days of waiting before quick processing became the norm), and hope to high heaven that they actually came out and you didn't waste all that time and money on a bunch of useless shit.
People have it pretty easy now, compared to even 25 years ago. And I embrace it wholeheartedly. Now, the camera and lenses are the biggest expense. No need for film, or a darkroom, or all the chemicals and equipment you once needed. Take all the photos you want, without fear of running out of space on your memory card that can hold hundreds, or even thousands, of images. All of that, and instant results! Nice, eh?
You don't need a film camera of yesteryear to slow down though. Take a moment, breathe, look around... I mean really look. Compose your shot, and take the photo. One Photo. Only one. Done.
Disclaimer: One Click doesn't mean you can't take the time to move things around (including yourself) to create the image you are after.
Having spend a good chunk on time shooting with film, I still tend to default to slow and composed when shooting. It allows me to slow down and think about what it is I want to capture. It opens up an entire new world of opportunity to see.
