How to recover the camera's raw image files



A raw image is a raw data in which a CMOS or CCD image sensor converts a captured light source signal into a digital signal. A raw file is a file that records the original information of a digital camera sensor and records some metadata (metadata such as ISO settings, shutter speed, aperture value, white balance, etc.) generated by the camera. raw is an unprocessed, uncompressed format that can be conceptualized as "raw image encoded data" or "digital negatives". The full name of the raw format is the raw Image Format. 


1:Raw files are information that is directly processed from CCD or CMOS without processing. Through post-processing, photographers can maximize their artistic talent.

2:The raw file does not have a white balance setting, but the real data has not been changed, that is, the author can adjust the colour temperature and white balance arbitrarily, and there is no loss of image quality.

3:Color linearization and filter row row transform are processed more quickly on the computer with a microprocessor, which allows the application of some more complex algorithms that are not allowed on some cameras.

4: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. 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.
