Where do FotoWare applications store soft-crop information?
FotoWare software allows storing of soft-crop information in metadata. This way, it is possible to create a suggested crop without physically altering image data or stripping information away from a file. Hence, a workflow can be configured to crop a copy of the file, while the original file remains untouched with the suggested crop intact.
Soft crop information is standardized in XMP, and is stored in the Camera Raw namespace: http.//ns.adobe.com/camera-raw-settings/1.0/
