What data is kept when "keep EXIF" option is selected?
If you choose to remove EXIF data using this plugin option
please note that Comments, IPTC and XMP markers will also be removed.
If you choose not to remove EXIF then the Comments, IPTC and XMP markers will be kept.
Please note that ICC (Color Profile) data will not be removed regardless of the "Remove EXIF" setting. The reason for this is that removing the ICC color profile could lead to images with altered colors.
