What can a picture tell you?
2012-02-05
A picture can tell you more than what you can see outside. Every time, a picture is taken by a digital camera, it embeds information like
- Date
- Time
- Camera Name
- Lens
- Focus
- Exposure
and it can sometime can embed GPS information. That means, it may carry location information. So you may want to be careful what picture you put up on your blog or other SNS. Those information can be access using software like iPhoto.
