Doy un ejemplo de exiftool para su uso en un mac. El uso de exiftool en la línea de comandos de Windows será el mismo. He oído mucho acerca de exiftool. Escribí un applescript para utilizar esta herramienta. Usted podría utilizar cualquier idioma que te gusta.
Supongo que usted se conecta tu iPhone a un mac, pero algunos de los conceptos que deberían aplicarse. Applescript se supone debe ser legible para todos. Es en "inglés".

(* *)
is a comment
--
is a one line comment
set a to b
is a = b in normal languages
log
is a print statement
display dialog
put up a dialog box
common(dropped_items)
means call function common with argument dropped_items
on common(input)
is the function header

This script provides an example of using the command line ExifTool tool.
The script was written to answer ASC Discussion question https://discussions.apple.com/thread/8511361
Shows exif data before and after any change. You may run the script by either double clicking on the app or droping files on the app. I Included debugging statements on run path.
Requires ExifTool by Phil Harvey. Download
https://www.sno.phy.queensu.ca/~phil/exiftool/
You need to place exiftool in your default path. I suggest "/usr/local/bin/exiftool". No you cannot go into terminal and alter your path.
You can alter this script to change the path.
Input:
Drop files on AppleScript icon.
or
double click on the app.
or
run from the script editor to see the log output. You will fist need to click on the "list" icon at the bottom of the script editor screen.
Output:
Creates file "tryAttachmentsLog.txt" in you home folder.
When run from the script editor, you get logged output.
How to save:
Save as an Application Bundle. Don't check the two boxes below.
For testing, run in the Script Editor.
1) Click on the Event Log tab to see the output from the log statement
2) Click on Run
