Sony DCR-TRV39 - Manual (Page 83)

Selecting individual thumbnails provides you with a wide variety of information, including
that which relates to Exif formatted files. In particular, these files contain all sorts of
information relative to specific dates/times, camera information, and camera settings. This
view also allows you to add your own information, such as titles and comments that will help you
remember certain details associated with individual files. A small preview pane (described below) is also
available.
