1: RAW files are almost unprocessed, in fact, receive information directly from CCD or CMOS. through post-processing, the photographer can maximize his artistic talent.
2：The RAW files do not have a white balance setting, The real data has not been changed, and then, the author can adjust the color temperature and white balance arbitrarily, and there is no loss of image quality.
3：Although the raw file is attached with mark information such as saturation and contrast, the actual image data does not change. The user is free to personally adjust a picture without having to base on one or two pre-set modes.
Perhaps the biggest advantage of raw is that it can be converted into a 16-bit image. That is, there are 65,536 levels that can be adjusted, which is a big advantage for JPG files. In fact, this is very important when editing an image, especially if you need to make important adjustments to the shadow or highlight areas.
1：Compared to JPG, the same photo, the size of the photo is often 5-10 times that of JPG, which is not conducive to network transmission.
2：Reading and editing require the special software.
3：Because of its huge size, the camera’s continuous shooting speed, photo saving speed, and preview speed are slower than JPG.
