Modify the picture exif information introduction
Interchangeable image file format (English: Exchangeableimagefileformat, officially referred to as Exif) is specially set for digital camera photos, which can record the attribute information and shooting data of digital photos.
Exif was originally developed by the Japan Electronics Industry Development Association in 1996 and version 1.0. In 1998, it was upgraded to 2.1, adding support for audio files. In March 2002, version 2.2 was released.
Exif can be attached to JPEG, TIFF, RIFF and other files to add the content of digital camera shooting information and the version information of index map or image processing software.
Windows7 operating system has native support for Exif. Click on the picture with the right mouse button to open the menu, click the properties and switch to the details tab to view the Exif information directly.
Exif information can be edited arbitrarily, so there is only reference function. The Exif message begins with 0xFFE1, and the last two bytes represent the length of the Exif message. Therefore, the maximum Exif information is 64kb, while the internal format is TIFF. [1]
