EXIF and MacOS X
I have listened to Stop 43, and the British Journal of Photography I have read what Tim Bray has to say and decided I may need to ensure that my picture’s EXIF data is accurate.
You can’t give away what you don’t own, and it seems you need to assert ownership of pictures. The way to do that is via image meta data, known as EXIF.
I plan to use reveal.app on MacOS X 10.5, which has its home here.
