What do JPEG, TIFF, pdf, raw and so on stand for?

JPEG format is the most efficient and important compression program in various platforms, and it is also a very popular compression standard. Different from TIFF format, it is a lossless compression format, while JPEG format is a destructive compression. JPEG format sacrifices image quality to save more file space, but fortunately, JPEG format also allows you to choose image quality when archiving. This TIFF(Tag Image File Format) format was developed by Aldus on the Mac platform in the early days, and now it has developed into a super format across WinPC and Mac platforms. TIFF format supports almost everything, and it has become an industrial standard in recent years because of its compatibility and support for WinPC and Mac platforms. Tiff:Photoshop will let you choose IBM PC or Macintosh format when saving Tiff format, and whether to LZW compress the image. This compression method called lossless compression is also supported by a large number of image editors and desktop typesetting software. These versions, including FreeHand, PageMaker, QuarkXPress and Illustrator6.0 after 6.0, can import compressed TIFF format images, but some software still does not support this compressed TIFF format image. Pdf: Save it in this format and you can open it on any computer! Raw:Raw format is an uncompressed and unprocessed data file captured by the image sensor of a digital camera. In digital photography, it is equivalent to negative film in negative film photography. One of the main benefits of the RAW format is that it allows photographers to postpone the application of multiple adjustments, so they can be more flexible to adjust in the way that is most suitable for the image in the future. As far as picture setting is concerned, RAW files provide photographers with more control options.
