Problembeschreibung:
Ich verwende Dropbox, um Fotos von meinem Smartphone mit meinem Laptop zu synchronisieren. In der Vergangenheit habe ich ein Befehlszeilenprogramm namens jhead verwendet, um die Fotos basierend auf den JPEG-Exif-Metadaten automatisch zu sortieren und umzubenennen.
Beispielsweise dieses Skript:
#!/bin/bash
jhead -model GT-I9100 -n%Y/%m-%B/User1-%Y-%m-%d_%H:%M:%S *.jpg 2> /dev/null
jhead -model P999 -n%Y/%m-%B/User2-%Y-%m-%d_%H:%M:%S *.jpg 2> /dev/null
würde jedes Bild basierend auf den JPEG-Exif-Daten umbenennen. Alle Fotos, die dem Kameramodell GT-I9100 entsprechen, würden mit „User1“ im Titel benannt, gefolgt von Uhrzeit und Datum der Aufnahme des Fotos. (z. B. ./2015/02-February/User1-2015-02-07_16:37:52.jpg), und dasselbe gilt für Modell P999 und User2.
Leider (oder zum Glück) besitzen Benutzer1 und Benutzer2 beide die gleichen Smartphones, sodass ich nicht mehr nach Kameramodell sortieren kann, da es sich bei beiden um SGH-I747M handelt!
Frage:
Gibt es eine andere Möglichkeit, anhand von Exif-Metadaten oder auf andere Weise zwischen Smartphones derselben Marke und desselben Modells zu unterscheiden?
Mich interessieren die folgenden Exif-Tags. Vielleicht steckt da irgendwo eine eindeutige Kennung drin:
