Digital Photos Give Away a Camera's Make and Model

fugu Re:What about multiple cameras using the same sens (260 comments)

After the sensor takes the RAW data, the camera processes the image (some noise reduction, curves, and compression) to get a jpg. Since this conversion would vary between manufacturers (or even RAW software) I'd imagine that the process would leave behind similar "fingerprints."
