All date/time values have the following format: YYYY:MM:DD hh:mm:ss. E.g. 11th of May 2006, 2:40PM would be represented as: 2006:05:11 14:40:00.

For more details regarding interpretation of these values, refer to the EXIF specification.

Default value is "" (no EXIF data is extracted).

## Remarks

To get an uploaded EXIF value at the server, you should extract POST field which is named in the following way: XXX_N , where XXX is a string value specified in this property (EXIF field name), and N is the number of the file in the request.

E.g. if the property value is ExifDateTime;ExifOrientation;ExifModel, you will get the following POST fields:

- ExifDateTime_1, ExifDateTime_2, etc.
- ExifOrientation_1, ExifOrientation_2, etc.
- ExifModel_1, ExifModel_2, etc.

If you prefer to extract EXIF fields on the server, you can get them from the source file, or specify to preserve EXIF fields in the thumbnails you are going to upload. To do it, use UploadThumbnail1CopyExif, UploadThumbnail2CopyExif, UploadThumbnail3CopyExif, and UploadThumbnailCopyExif properties.
