What does RAW mean in the camera?

The full name of RAW format is RAW Image Format, which is called original in programming, that is, the original file without any processing. There is all the information that the camera can record.

RAW files are almost unprocessed information obtained directly from CCD or CMOS. Through post-processing, photographers can maximize their artistic talents.

Extended data

RAW format photos have a very high tolerance, that is, they have a very large adjustable range. Make full use of their high tolerance characteristics, through appropriate post-processing, we can get more beautiful photo effects, and even treat "waste films" as "large films". RAW format is characterized by high tolerance, because it records a large number of original data, and users can adjust freely within the range of original data records to realize the beautification and correction of photos.

RAW format photos only call the original data when processing, so they have the inherent characteristics of lossless processing. The adjustment parameters can be saved separately and modified at any time, which improves the work efficiency during modification and will not cause any destructive adjustment to the original photos.

When saving in RAW format, it can reach 60~ 100M, while shooting in JPG format with the highest quality is only 15 ~ 20 m. By comparison, we can see that the size of RAW format is much larger than that of JPG format.
