Thanks! You are correct, when I did a dump with `xxd IMGP0847.DNG > output.hex` it wasn't showing up for some reason.... But your command worked (though my dd doesn't like hex values so I needed to get decimal via printf "%d\n" 0x3E40B).

Curious if you (clearly smarter than me) know why it didn't show correctly in the xxd or hexdump for the file. Would love to learn.

  xxd IMGP0847.DNG | grep 03e400:
  0003e400: ffd8 ffc3 000e 0e10 800c 5002 0011 0001  ..........P.....

Look at the byte at offset 11 (0xb), it's there.

Ohhh the b offset (11) is an offset _on that line_ (0003e400)! I got it now:D This thread taught me a great deal. Thank you, MajesticHobo2!
