Transferring Images with a Caption
You can add a registered caption to each image before transfer. This is convenient if you
want to inform the recipient of the printing quantity, for example. The caption is also added
to images stored in the camera.
You can check captions added to images by examining the user comments in the Exif
information.
Captions can be created and registered with EOS Utility (
