This is the digital equivalent of KwikFotoPrintz.

They programme your camera to develop and process all your photos, plus everyone else’s who has a camera like yours, according to how they think your image should look. They decided how your photos should look depending upon its mixture of colours and tones and upon which art filter or effect you applied. Teams of extremely clever technicians work in laboratories, probably in Japan. Think of raw files as being the negatives and jpegs the prints. You had control over the process and therefore more control over how the prints appeared. If you had your own dark room, you could develop your own negatives and then process your own prints. Processing the paper in chemical baths to develop the image, the Laboratory applied a standard process to all the thousands of photos that arrived in those envelopes. From that negative they would produce prints, exposing photosensitive paper to light that was shone through the negative. They developed the film to create a negative. Films were sent away in colourful, pre-paid envelopes to KwikFotoPrintz, or similarly badly spelt photographic laboratories. In days of old, we took photos using film cameras film photography is increasing in popularity again, which is great. So, what’s the difference between raw and a jpeg (.jpg)? (There are 256 shades of grey including black and white, not 50!) Mixing these tones with Red, Green and Blue (RGB) creates all the colours that go to make up your photograph. Filled to the brim they are white with a numerical value of 255. With no light they are black with a numerical value of 0. Imagine these photosites as tiny cups that fill up with light.
That pattern approximates the proportions of red, green and blue light-sensitive cones on your retina in your eye. In most cameras, photosites are set in a Bayer Pattern, a pattern of red, green and blue dots. The camera’s processor reads these electronic signal, storing them on the memory card as a raw file.
