Ever wonder how film works? A recent video from SmarterEveryDay covers this topic in great detail describing how film works.
Over the last few years, the popularity of film has been increasing quite dramatically. For instance, Kodak has had to increase its production by more than double over the last few years. The younger generation of photographers that missed out on the film era seem to have rediscovered it. And it seems the tactile and tangible nature of film photography has enticed a wide range of photographers back to it.
Some people describe film photography as being more authentic and having more life to it. Of course this is a subjective matter, however, there may be something to the claim. The light photons from any given scene are in a sense physically captured on film. In essence you are literally taking a piece of the moment and storing it on film. Once you develop the film you reveal the image you captured.
With digital, there are lots of interpolations and clever tricks to mimic the scene, but it's simply not the same. This could be one of the reasons why some describe images taken on film to have a beating heart, or a certain lifelike warmth to it.
Whatever the case, it's definitely interesting to see how film actually works. The video linked above from SmarterEveryDay covers this topic with a surprising degree detail. I highly recommend you check out this incredible video.
