Question about Exif Data on Jpegs & Forensic Limitations
I was referred here by Irongeek on one of his tutorials about Exif data. I was hoping someone here could help me with this question.
Regarding Exif data on Jpeg photographs, specifically the "picture being taken day" -- What are the forensic limitations on the 'picture being taken day?'
When and how can this data be changed? Is it ever changed automatically when editing the photograph, resizing, making a caption or sidebar, etc...If the Jpeg photo says photoshop 3, and has a picture being taken day of say 6/1/2010, is it possible that the 'picture being taken day' is wrong or not the actual day the picture was taken?
What does it mean exactly when a picture has a digital stamp saying 'picture being taken day' as 6/1/2010?
I have more questions but this will head me in the right direction as a good start.
