Oie... For some reason I thought you were referring to the "Subject" field in the EXIF information......
Today is s different day, different interpretation. ("Subject Distance" field)

A common practice is to use the main subject in a shot to acquire focus lock. That way the distance to the focus point is also the distance to the subject. To acquire that data, all the camera needs to do is identify the focus point (the point used to achieve focus lock). All cameras will be able to do that and I suspect that most cameras could, if required, calculate the distance to the focus point, or provide a reasonable approximation. To be able to identify a specific subject within a frame would require some sort of AI - which most cameras don't have... yet.

Why would you assume that the reason is to "improve the image"?
Maybe he just wants to know how far the subject was from him.

The purpose of having that information is to have that information. This is the information age. Information is king. It is the all-consuming goal of a lot of us nerds.

For what possible reason?

You never wondered how far something was from you?
I have.
Simply curiosity...

I would love to have it, if it were available, especially when reviewing flash photos.

According to this (comprehensive) list, there is a focal-distance record:
0x9206 SubjectDistance rational64u ExifIFD
How to access this information I have no idea . . . .

Windows will display the Subject Distance under "details", IF there is an entry in the field.
For the field to be populated, the camera would have to write it.
(Or, one can manually enter/alter the information in that field via Explorer.)
