    If you open photo in hex editor you will find half the file is filled with repeating garbage, not JPEG data. This file can't be repaired.Corrupted JPEG images-2019-09-20-2-.png

    In general a hex editor like HxD can tell you a great deal. So, if you have half grey images do:

    - Check file size compared to other intact files. If on average photos are say 2 MB and the corrupt photo is only 800 KB then it's simply truncated.

    - Open file in HxD and page-down through it. It starts with a header with some readable text here and there even. At some point data becomes random (high entropy). If at some point entropy drops (all zeros, or FF bytes or some repeating pattern) then although file may be correct size, the data inside the file is missing.

    - If high entropy remains throughout file and last 2 bytes read 0xFF,D9 THEN you may have a file that can be repaired using something like disktuna's jpeg repair utility.
