Question :
During a trip with (business) friends, I have taken photos with my iPhone myself. But in the Photos.app, they have gotten mixed up with the photos taken by my friends, that I have received though Whatsapp… but als it turns out, those ar in a far more basic photo resolution then my own pictures…

Is there any way to separate the photos taken by me from the ones taken by others ?

Answer :
Yes, it is possible to select only the photos taken with your own iPhone.
To do that, do this :
– on your iPhone, open the Settings.app
– in the Settings page, scroll down and select “General”
– then, in the top of the General page, select “About”
– then, in the top of the About page, at “Name”, see the name of your iPhone (and remember it)
– then exit the Settings.app and open the Photos.app
– now, in the page that opens, click on the “Search” icon (bottom right)
– then, in the page that opens, in the top search bar, typ the name of your iPhone (the name that you have just found in the Settings.app)
– then, in the search results, you will get a preview of 9 photos taken with your own iPhone
– now, just above the top right photo preview, click “See All”
– on the next page that opens, you will now find all the photos taken with your own iPhone

That’s it !

enjoy 😉

NOTE : there is not easy way (yet) to search for photos NOT taken with your own iPhone in iOS at htis moment… that should be done in the Photos.app on your Mac
