Binary package “exifprobe” in ubuntu trusty

Read metadata from digital pictures

 Exifprobe reads image files produced by digital cameras (including
 several so-called "raw" file formats) and reports the structure of
 the files and the auxiliary data and metadata contained within
 them. In addition to TIFF, JPEG, and EXIF, the program understands
 several formats which may contain "raw" camera data, including MRW,
 CIFF/CRW, JP2/JPEG2000, RAF, and X3F, as well as most most
 TIFF-derived "raw" formats, including DNG, ORF, CR2, NEF,
 K25/KDC/DCR, and PEF.
