Can you please post an example of the proper standard date/time format? I know that I rename any images I save so that I know what they are. I would gladly copy and restore the original file names of my files if I was certain of their format.

MainCamera_20120405-173900.jpg

Camera1_20120325-065900.jpg
Date and time are on each picture if they haven't been cropped.
The naming syntax can also be reviewed on any photo in the archive
Let me confirm:
The information taken from left lower corner of the
unaltered picture,
Main Apr 5, 2012 17:39 EDT 46F/8C using this formula, when hours are military time (24 hour, not 12 hour) and seconds are always "00".
MainCamera_YYYYMMDD-HHMMSS.jpg translates to
MainCamera_20120405-173900.jpgAnd the camera names are
MainCamera_
Camera1_
Camera2_
Camera3_
Camera4_
Correct?
