Is it possible to remove the time element of the captured date/time data capture in the exif data? When I display my photos by creation date I get both the date and the time the picture was taken - what I would like to be displayed is just the date. I have come across many exif editors that allow the time data to be changed but not removed.
You can set an EXIF date/time tag to whatever you want. By default, ExifTool does some validation of the date/time value, but this is disabled with the -n option, allowing you to write anything you want:
> exiftool a.jpg -createdate=now
1 image files updated
> exiftool a.jpg -createdate -G1
[ExifIFD] Create Date : 2012:11:26 07:09:18
> exiftool a.jpg -createdate="this is a test"
Warning: Invalid date/time (use YYYY:mm:dd HH:MM:SS[.ss][+/-HH:MM|Z]) in ExifIFD:CreateDate (PrintConvInv)
Nothing to do.
> exiftool a.jpg -createdate="this is a test" -n
1 image files updated
> exiftool a.jpg -createdate -G1
[ExifIFD] Create Date : this is a test
In your specific case, the EXIF specification actually allows any date/time component to be empty (filled with spaces), so you should do something like this:
exiftool -createdate="2012:11:26 : : " -n a.jpg
