Hi all,

I’m in the process of beginning to back up all my photos to a couple of external hard drives and have a question regarding file sizes.

When looking at a particular photo, the file size in the photos app on iOS and MacOS is showing as 3MB (see screenshot). However, when I export on my Mac using the export unmodified original option, it splits it into two files (photo and a 3 second movie which is obviously the Live Photo part). However the image comes in at 3MB and the movie is 4MB meaning a total of 7MB. Yet the photos app only sees it as 3MB? Why is the photos app giving a false figure?

When taking into account iCloud storage (I have 6TB), is this one photo taking up 3MB of storage or 7MB of storage?

Thanks!
