How much does it suck to transfer a few hundred photos from your camera, only to afterwards notice the date on the camera was wrong? So, here I go looking for an EXIF batch updating program, and the pickings are much slimmer than I would expect. Of course, writing my own seems like a pretty viable option and the EXIF.py module would be grand to apply here, save for one problem: It was written in 2002 and it still doesn't write back to the image.
What's a dad with hundreds of family photos to do? Fix it. Talked with someone else interested in this and came up with three options to move forward.
- Replace the entire module with a ctypes wrapping over the libexif library.
- Jam EXIF writing into the existing module by invoking the exif command-line utility.
- Reverse engineer the EXIF format from the modules parsing functions and properly implement writing into the library.
If anyone knows that this is futile and a solution already exists, please let me know.
