Ever wondered if that UFO photo or sasquatch sighting is a fake? ... or if that camera manufacturer's sample images have been touched up?Simply open an image in JPEGsnoop and scroll down to the section titled, *** Searching Compression Signatures ***. This option can be enabled/disabled with the Signature Search item in the Options menu.The utility will compare the compression characteristics of the photo against an internal database of thousands of camera "signatures" to locate a match. If a match is found, the matching digital camera or editor is shown. If the signature matches a photo editor (such as Photoshop), then there is a good chance that the photo has been edited (i.e. not original!).The assessment line indicates one of four possible outcomes:Class 1 - Image is processed/editedClass 2 - Image has high probability of being processed/editedClass 3 - Image has high probability of being original -- NOTE: Please see description below!Class 4 - Uncertain if processed or originalDownload
