Digital Photos Give Away a Camera's Make and Model

holy_calamity writes "Engineers at Polytechnic University Brooklyn have discovered that digital snaps shorn of any metadata still reveal the make and model of camera used to take them. It is possible to work backwards from the relationships of neighboring pixel values in a shot to identify the model-specific demosaicing algorithm that combines red, green, and blue pixels on the sensor into color image pixels. Forensics teams are already licking their chops."

I think he/she continued the joke but honestly, on Slashdot you can never tell for sure. Maybe I'm joking.

I knew there was a reason

to still use film like I do. And at, that to be using a film camera of a type rare enough that the police don't even have examples to compare to.... (40,000 or so made worldwide over 11 major models and 40 years. I own 5 of them across 3 models (well 2 models and 1 submodel) - Alpa of Swizterland. Look under Wikipedia and the photos are my cameras.)

Enter...The Pedantic Avenger!!!

with less digital artifacts

That should be "with fewer digital artifacts".

Take THAT, Mr. Camera Smartypants. You are being punished for the crime of being knowledgeable about an esoteric field, and making us all feel stupid.
