Looks like typical weak technical journalism from New Scientist to me. A 90% probability of correctly identifying the right model of camera. It's not going to be a great help. I reckon most images will have that data in the EXIF already!
 
If they were really smart they would read my name, website and copyright info from the EXIF ;)

I love this:

Pollitt believes that this technique can still be used forensically. He says that because digital cameras have a shelf life of only 18 months, this can help to narrow down when and where it was sold.

18 months? He's having a laugh. I wish I could replace my cameras every 18 months.
 
Camera serial numbers are written to EXIF - what else do they need?
 
What a complete loads of *******s of an article.
 
18months.............

The way photography's gone in the last 18 months how many, say, D40's or EoS 400D's etc have been sold. Doesn't narrow it down that much does it.

I can imagine Poirot now "so we have a Nikon D40 as exhibit no. 1...hmmmmmm, get me the list of 1.5m people who have one of those... I want a fit on each of them by 8pm"

If they're going to write a technical article about photography, they could at least get someone to write it who knows the different between a camera and a cow's ar$e.
 
It's easy enough to narrow it down to 50/50 anyway.....bad picture, Nikon.....good picture, Canon ;) :lol:
 
Should be called The Ancient Scientist! :D
 
Can't see much difference between this and the way colour laser printers print a microdot containing traceable information on each print they produce.
 
I think some scientist had way to much time on his hands .
 
Can I have my 30 seconds back please.
