Anyone can add tons of contrast and saturation and come away with a “stylized” image, but not everyone has the restraint to add just the right amount of contrast or saturation. The same is true with Instagram filters. Back when Instagram first launched, filters were either on or off; there was no middle ground....

Film photographers had it easy. They could just click the shutter button and their photos would look awesome. Each film had it’s own unique look. It was simple to look at an image and go, “Oh, that was taken with Kodak Ultra”, or, “That was obviously shot on Tr-X”. Digital photographers, on the other hand, don’t have that luxury. While each film treated a scene differently and choosing the right film for the job was part of the photographic process, digital sensors all try to capture a flat, neutral exposure....
