What raw data does the photo contest need?

Each digital photo initially contains EXIF information, such as shooting date and exposure parameters.

To view and copy the EXIF information of a photo, you can use the photo browsing software "ACDsee" installed on each computer to open the photo, right-click the photo and select "Properties" to view the EXIF information of the photo.

Here, you can also modify, copy and delete the EXIF information of photos at will.

Specific operation: in the EXIF information bar, select the EXIF information item to modify or delete the photo, just like the operation of "Rename the file" (double-click to start modifying, copying and deleting the content).
