The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
CR3 files are original raw files recorded by Canon's new cameras using the Digic8 image processor. Currently, only three cameras, Canon EOS M50, EOS R, and EOS RP, support the CR3 recording format. (Similarly, after the Digic8 processor, a new "raw compression format" - CRAW, is derived, which is also a new file format unique to these three cameras.
cr3 files can be opened through Canon ddp, DPP is the abbreviation of "Digital Photo Professional". It is a software that performs image adjustments such as "RAW development" on RAW images taken by Canon EOS series digital SLR cameras. So it is recommended that you use DPP 4.9 to decode CR3 files. Then use the transfer function of DPP to convert the CR3 file into TIF format and import it into PS. Over time, a new plug-in version should be provided.

Why should you use raw format when retouching pictures?
There are three main benefits.
1: Quality: The original data obtained directly from the photosensitive element has the most layered records. The largest PRO HTOTO RGB Color space. A special format for digital cameras. It is a true "electronic negative", an undisputed original image. It is the only format that can express the ultimate quality of digital camera images.
2: Post-production: Pre-stage settings Only the ISO and exposure are correct or not, and the rest can be adjusted later. It provides room for adjustment and processing in the later stage, and becomes the true meaning of post-production restoration and re-creation.
3: Guarantee: Guarantee copyright ownership. When pictures are stolen by others, RAW files can be used as the strongest evidence of copyright.
What is decoding? Why decoding? How to decode?
Encoding can be understood as compression Well. JPEG is an encoding method. Since there is encoding, there must be decoding. The purpose of compression is to reduce storage space, so that storage or transmission can save time and effort. Of course, it needs to be restored after compression. This restoration is decoding.
Compressed (encoded) data. When you want to see the data, you will use a photo viewer to view the photo. Then this viewer will help you decode the photo and display it to You see. This decoding is decoding in the viewer. However, you should now want to decode without going through the viewer. Decode and see it yourself. Then you have to implement the decoding algorithm yourself. How to decode. There are ready-made decoders. Library, you can also learn the decoding algorithm yourself and then decode it yourself. However, depending on the question you asked, it may be more appropriate to use a ready-made decoding library.
