 Export photo from the Photos library to another destination on disk.  
-- First argument dest must be valid destination path (or exception raised).
-- Second argument *filename (optional): name of picture; if not provided, will use current filename
+- dest: must be valid destination path as str (or exception raised).
+- *filename (optional): name of picture as str; if not provided, will use current filename
 - edited: boolean; if True (default=False), will export the edited version of the photo (or raise exception if no edited version)
 - overwrite: boolean; if True (default=False), will overwrite files if they alreay exist
 - increment: boolean; if True (default=True), will increment file name until a non-existant name is found
+- sidecar: boolean; if True (default=False) will also write a json sidecar file with EXIF data in format readable by [exiftool](https://exiftool.org/); filename will be dest/filename.ext.json where ext is suffix of the image file (e.g. jpeg or jpg)
 
 If overwrite=False and increment=False, export will fail if destination file already exists
