+  Based on the analysis of compression characteristics and EXIF metadata:
+
+  ASSESSMENT: Class 4 - Uncertain if processed or original
+              While the EXIF fields indicate original, no compression signatures 
+              in the current database were found matching this make/model
+
+  Appears to be new signature for known camera.
+  If the camera/software doesn't appear in list above,
+  PLEASE ADD TO DATABASE with [Tools->Add Camera to DB]
