I'm writing some scripts to organise my photos and I would like to sort out the photos I took myself from the mix of photos that are on my iPhone.
For example, sometimes I get sent photos via AirDrop or messages and they all end up in my photo library.
I can get the Make and Model from the Exif tag, so that helps to some extent, but is not sufficient in all cases.
I have looked around in the Exif and TIFF data, but there is nothing obvious.
