JPEGsnoop

you may know, any image file contains a lot of hidden information about itself and the way it was taken or edited. JPEGsnoop scans the image and offers you all that detailed information called EXIF data which contains information about camera, edition program, date, color histogram, compression format, etc. What we have to stand out from the large list of features is that the program tells you if the phot has been edited or not. That's a good way to know if that beautiful person is original or has been 'photoshopped'. JPEGsnoop supports a good bunch of image formats, including: JPG, THM, AVI, DNG, CRW, CR2, NEF, ORF, PEF, RAW, MOV, and PDF and offers you the possibility to export information as TXT.
