It’s a sad truth, but film photography has gone the way of the DoDo bird. And if you’re not familiar with that expression, then I’ve pretty much made my point. That said, the vast majority of the population, even most professional photographers shoot using digital. So as a result, most photographers, barring the real professional ones, shoot in auto mode and have no clue what their camera’s manual settings actual mean in real world use.
Fortunately, someone created this handy infographic to provide some insight (scroll down to see the complete infographic). Now, to be candid, it’s far from perfect and it really only touches on three major points about photography. But if anything it provides some insight into where the terms comes from.
For instance, ISO, which is still used in digital photography, originally related to the speed of the film. And the speed of the film is important, because the faster it is, the less light you need to “expose” it. The slower it is, the more light is needed, but with that comes a smoother, less grainy image.
To be candid, I don’t miss film. And yes, I’ve shot film, I’ve developed film, and I’ve printed prints using not a printer, but an enlarger. I’ve also used a light meter, which would likely confound anyone under the age of 30 if shown one today.
