In this issue, the editor will bring you what the meaning of raw photos is. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Raw photo refers to the unprocessed and uncompressed photo format, because the original meaning of raw is "unprocessed", which can be understood as "RAW image is the raw data that CMOS or CCD image sensor converts the captured light source signal into digital signal".

The original meaning of RAW is "raw". RAW image is the original data that the CMOS or CCD image sensor converts the captured light source signal into digital signal.

RAW file is a kind of file that records the original information of the digital camera sensor and records some metadata (Metadata, such as ISO setting, shutter speed, aperture value, white balance, etc.) generated by the camera. RAW is an unprocessed and uncompressed format that can conceptualize RAW as "original image encoded data" or, more vividly, "digital negatives". The full name of the RAW format is RAW Image Format, which is called primitive in programming.

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

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 color temperature and white balance arbitrarily, and there will be no loss of image quality.

(2) Color linearization and filter row-column transformation are processed more quickly on computers with microprocessors, which allows the application of more complex algorithms that are not allowed on cameras.

3 although the RAW file contains marker information such as saturation and contrast, the real image data has not changed. Users are free to make personalized adjustments to a particular image without having to base on one or two pre-set modes.

Perhaps the greatest advantage of RAW is that it can be converted into a 16-bit image. That is, there are 65536 levels that can be adjusted, which is a big advantage for JPG files. This is important when editing an image, especially if you need to make important adjustments to the shaded or highlight areas.

The above is the meaning of the raw photos shared by the editor. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
