14 Jan 2008 Rename image files according to EXIF date
This rename trick can be run in Windows, Linux and even Mac since the commandline program I’m going to use, exiv2, is available in all three platforms. Rename all image files in current folder to the format YYYYMMDDHHMM_Filename.EXT
This has been tested on my Nikon D80 JPEG and NEF image files.
Linux
exiv2 -r'%Y%m%d-%H%M_:basename:' rename $(ls)
Windows (from the command prompt)
exiv2.exe -r %Y%m%d-%H%M_:basename: rename d*
Windows (in a MS-DOS batch file)
exiv2.exe -r %%Y%%m%%d-%%H%%M_:basename: rename d*
You have to add an extra % if you are going to use exiv2 in a Windows batch file, because % in batch files is treated as a variable and not as a switch to exiv2.
These examples require that you have access to the exiv2 program from the current folder.
Result
Now my image files have names like
20071022-1202_DSC_9727.JPG 20071022-1202_DSC_9727.NEF
Change in workflow
Since I rename all my files in the format YYYYMMDD-HHMM_Filename I’ve included it in my image “workflow” (a simple MS-DOS batch file) I wrote about in Rotate images depending on the EXIF orientation post.
This has been tested successfully on the Windows exiv2 version 0.16
The new batch file can be downloaded here.

23 May 2007 Rotate images depending on the EXIF Orientation Tag
Automatic rotation of JPG images (inclusive EXIF thumbnail) can be performed by using jhead.exe and jpegtran.exe in Windows.
jhead -ft -autorot *.JPG
All JPG-files in that folder will be rotated and file time (time and date of exposure) will be set according to the EXIF info.

12 Apr 2007 Embed copyright notices into JPEG images
Digital Cameras embed several types of data inside the images you take, including camera manufacturer, date the picture was taken, and aperture, shutter speed, and focal length settings. These are called EXIF tags and are also called “metadata.” Here’s how to take advantage of these tags to embed your own copyright notice.
You’ll need the program exiftags to this excercise.
