Inspect EXIF Data For An Image File

The exiftool CLI (which can be downloaded via brew) is a useful tool for inspecting all the EXIF data attached to a media file. A media file like an image has a bunch of additional details embedded in it like timestamps, image metadata, and sometimes location information.

Here is all the data attached to a screenshot I found on my desktop:

This works with other kinds of media files. For instance, I ran this against an MP4 screen recording file which contained even more metadata.

In addition to reading data, exiftool can also write it. See man exiftool for more details on what else it can do.
