Hi guys,
I can honestly say that I have pretty much never taken a photo in my life, zoo animals when I was about six being the only exception.
So I was hoping someone would be able to help me with a couple of questions that I need to get answered.
Firstly:
Is it possible to tell whether a photograph has been taken on a digital camera, or whether it has been taken on a normal camera, developed at the local chemist shop and then scanned onto a computer.
I know digital cameras can produce better quality in theory, but is it really that noticable? Does it depend on the quality of the scanner etc.?
Secondly, and this one will prove I have no idea:
Is it possible to tell whether two photos were taken by the same digital camera? Do they have some kind of digital watermark or the like that would be able to distinguish which camera they came from?
If so, how would this be done? Would it require someone very specialised to do this?
Thanks for any help,
Matt
