Editor to share with you what are the differences between jpg and raw, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Differences: 1. Jpg format is a compressed format, which stores less detail color information, while RAW is a lossless format with a wider adjustment space, and the adjusted image will not have data loss. 2. The adjustment range of jpg format is limited in the later stage, while RAW retains richer levels and details, which can be adjusted in depth.

Jpg format

JPEG (Joint Photographic Experts Group) is the product of the JPEG standard, which is formulated by the International Organization for Standardization (ISO) and is a compression standard for continuous-tone still images. The JPEG format is the most commonly used image file format, with the suffix .jpg or .jpeg.

JPEG compression technology is very advanced, it can use lossy compression to remove redundant image data, in other words, it can get better image quality with less disk space. And JPEG is a very flexible format, with the function of adjusting image quality, it allows files to be compressed with different compression ratios, supporting a variety of compression levels, the compression ratio is usually between 10 and 40, the greater the compression ratio, the lower the image quality; on the contrary, the smaller the compression ratio, the higher the image quality. For the same image, the file stored in JPEG format is the same as that of other types of files, usually only a few dozen KB, and the quality loss is small and can hardly be seen. JPEG format mainly compresses high-frequency information, retains color information well, and is suitable for application on the Internet; it can reduce the transmission time of images and support 24-bit true color; it is also widely used in images that need continuous tone.

RAW (image file)

The original image file contains data processed by an image sensor from a digital camera, scanner, or film scanner. They are so named because they have not been processed, printed or used for editing.

In general, the original image has a wide gamut of internal colors that can be adjusted precisely, and some simple modifications can be made before conversion, such as TIFF or JPEG file format storage. It is convenient for printing or further processing. These encodings often depend on the equipment of color images.

These images are often described as "RAW image files", although they do not actually refer to a single original file format. In fact, there are dozens of different types of digital devices that use this format (common in digital cameras or film scanners).

The original image files, sometimes referred to as digital negatives, play the same role as film negatives and are not used directly as images, but to create an image that contains all the information.

Similarly, the process of converting the original image file into a visual format is sometimes referred to as rendering the original image, which is equivalent to the metaphor used to convert photosensitive film into visual image in the process of film development. Image rendering is part of the process of white balance and color grading.

The difference between jpg and raw

1. The difference in the amount of information: jpg (JPEG) format is a compressed format, which stores less detailed color information. RAW is a lossless format with more room for adjustment, and there is no data loss in the adjusted image.

2. The difference of modifiability: due to the difference in the amount of information, the adjustment range of jpg format is limited in the later stage, while RAW retains richer levels and details, which can be further adjusted.

3. Difference in opening mode: jpg format is compatible with many devices and programs, which is more common, while RAW format needs to be opened using the corresponding camera or professional application.

These are all the contents of this article entitled "what are the differences between jpg and raw". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
