It is quite often that I forget to change the timezone of my camera when I visit other countries and it bothers me that the EXIF datetime stamp is inaccurate! Or, if we don’t sync the datetime between the 2 cameras, when I use my P&S and G uses his SLR, it messes up the order of the pictures when viewing them.
If you are as forgetful (and particular) as me, I have been using ExifTool to timeshift my photos. I can’t figure out how to use it as a standalone Windows program so I use it from the command-line. Installation is straightforward – just extract the zip file, rename and move it to the Windows directory.
There’s quite a lot of details on how to use it and in fact, I find it quite complicated. Anyway, I managed to figure out the command for timeshifting photos. And you won’t need to know other commands unless you need to change other EXIF data.
Example: The following command timeshifts your photos by +1 hour.
exiftool “-DateTimeOriginal+=0:0:0 1:0:0“ C:\Photos\temp\
- Replace the (plus sign) + with (minus) - if you need to shift the timestamp backwards.
- The datetime fields signify respectively: years:months:days hours:minutes:seconds. Replace the numbers according to your needs.
- Replace the directory name accordingly. The program will process all the photos in that directory.
- The program automatically backs up your original photo in the same directory.
Another program to share is for batch lossless auto-rotating of JPEG. It is called JPEG Lossless Rotator and G found it! Previously, I was browsing through the photos using FastStone Image Viewer and rotate them individually.
It’s a breeze to use, basically you just specify the directory and it will detect the photos to be rotated, then just hit the Automatic button. Voila! It replaces the original photos so make a backup if you want!
Now, you don’t have any excuse to mindlessly upload unrotated pictures to Facebook.
Hope this is useful!
Those are the 2 things I would do before archiving my photos. Let me know if you know of other software for doing this!
