What do you mean by raw taken by mobile phone?

Raw is the original image file shot by the mobile phone camera.

The original image file contains data processed from the image sensor of a digital camera, scanner or film scanner. They are so named because they have not been processed, printed or used for editing.

Usually, the original image has a wide color gamut, which can be adjusted accurately, and some simple modifications can be made before conversion, such as TIFF or JPEG file format storage.

JPEG format:

Corresponding to raw is JPEG format, which is a format compressed from RAW. The stored color information is not very detailed, and the post-adjustment range is limited. However, the RAW format needs to be opened with a corresponding camera or professional application, and its compatibility and universality are not as strong as JPEG format.

RAW format is more suitable for experienced photographers who need post-optimization of photos, while JPEG format is more suitable for direct users who don't need post-optimization.
