Let’s learn how that magic occurs.
Mild and Movie Pictures
After we press the shutter button of a movie digital camera the sunshine that has entered by way of the lens hits the movie. Photographic movie is roofed with plastic emulsion that incorporates photosensitive silver halide crystals. These crystals react to the sunshine chemically and the movie “data” the picture.

That’s it. In a nutshell, the RAW knowledge is the gathering of recorded values of depth of sunshine from every pixel of the sensor. Earlier than we will “paint with mild” we have to measure and recorded it.
