Why is it that when a photographer takes a picture, it is black and white on the display screen, but it is color on the computer?

Hello, according to professional photographers, this method is the RAW data storage of Canon, and the color style on 5D can directly shoot black and white images. However, the photographer used the RAW storage method when setting the black-and-white shooting mode. Because RAW itself is metadata, it records CMOS pixel data without any change, so the data stored in the card itself is not black and white, but the color style setting of 5D makes the image on the fuselage screen black and white.

(The original image file contains the original data obtained directly from the image sensor of a digital camera or scanner, and requires minimal processing. Raw formats are called Raw because they have not been processed. Therefore, it is usually impossible to edit, print or display these pictures in the browser directly using the bitmap editor. Generally speaking, the Raw conversion tool can accurately adjust image files in a large color gamut range, and then convert them into TIFF, JPEG and other image files, which is convenient for storage and printing. Usually, the converted file is device-dependent. Raw format is often considered as a single format, so it is called Raw file. In fact, various types of digital devices (such as digital cameras and scanners) use dozens or even hundreds of Raw formats.

Some people call Raw the negative of the digital age. )
