I'll tell you, but I guarantee you - it's not as cool as you think.
Picture files contain quite a bit of information - besides the visual information, that is. As it turns out, some of that information pertains to the origins of the picture. In other words, in most cases, a picture file KNOWS where it came from. So all a curious person has to do is save the picture, right click on it, and find that wonderful little tab called "properties."
Now, its' a fairly simple matter to scroll down to the part that contains information about the camera which took the picture.
But that's not all. Play around with it yourself. You may be surprised at what you find.
The process should be fairly similar. There are a a few good sites that talk about this in great detail. I would Google Search "picture properties on Mac."
ReplyDeleteI tried, and it didn't work. Are you sure it works on every single picture, because I tried it on a picture I downloaded from twitter, and it didn't work.
ReplyDeleteIt could be that Twitter, to reduce the amount of information it needs to store, erases such information and only retains the actual image. It's a just a theory.
