I am a teacher, and I am trying to verify the date and time when a student took a particular photo. The student has an iPhone (unknown model and OS version) and used the Scanner app by Luni to take the photo. The student says they can't find the date and time on their own, and I am not able to gain direct access to the student's phone due to covid-19 restrictions (the teaching is being done remotely).
I don't have (and have never used) an iPhone, but I assume that if the photo still exists on the phone there is a way to recover the metadata. Could someone point me towards a step-by-step tutorial for how to find a file's metadata either in this particular app or in whatever file manager iOS has built in?
To be clear the student is entirely cooperative, but seems to not be very technically knowledgeable (or even comfortable with technology), and my total inexperience with iPhones renders me unable to provide detailed, specific instructions. I have tried finding an iPhone emulator I can run on Windows, but I can't seem to find one which is free (or freemium) where I can easily see how to get to the app store.
Edit: If I get instructions for how to find metadata in a file manager, I will also need instructions for how to determine through the app what the location of the file is.
