what is film, and how does it work?
Photographic film is a thin strip of plastic coated with a layer of light-sensitive chemicals. When you take a picture, light passes through the camera lens and reaches those chemicals, creating a hidden image that can’t be seen yet.
The hidden image becomes visible during the developing process. The developer reacts to the areas that were exposed to light, creating a negative. That negative can then be scanned into a digital image or used to make photographic prints.
The process is surprisingly simple. Light records the image, chemistry reveals it, and the negative becomes the original source for every print and scan that follows.
