A photo or video's Date Taken vs. Date Created in Finder

I forgot to mention that the Get Info Finder solution (either cmd+i, or option+cmd+i) do not show DateTimeOriginal either, but may show other EXIF data.

You could send direct feedback to the macOS product team with a feature request to show the DateTimeOriginal timestamp in Finder for images that have it. The product teams do not participate in these user-supported communities and feedback is the only means of communicating with them. They may not respond though.

The Finder was not designed to inform you whether a creation date/time stamp on a random file is operating system generated upon file creation, or introduction to the operating system, or whether it represents the DateTimeOriginal time stamp used from the image EXIF data. You would need a different tool to determine that, and one such tool is Apple's Preview which can show EXIF data from its Inspector panel (see below).

If the Photo was introduced from the camera, directly to macOS via Apple's Image Capture, then the internal DateTimeOriginal EXIF data is used as the creation date for that image. That is Image Capture doing that.

If the image is introduced by any other means to the Finder, other than exporting from Apple Photos as unmodified originals (with EXIF data), then the operating system applies the current Date/Time, and not the internal EXIF DateTimeOriginal stamp to the file.

I have an image where I used Image Capture to transfer it from an iPhone to my Pictures folder. The Finder's creation date is identifical to its internal EXIF DateTimeOriginal timestamp. When you open a Finder window, it has an optional Preview pane that you can enable via Finder > View menu > Show Preview, and there is also a View menu > Preview Options that allows you to select/show some of those EXIF data items in that Preview pane. DateTimeOriginal is not however, one of them.

You can open the image in Preview, and open the Inspector (cmd+i) and on that Inspector panel will be an information ⓘ icon. When you click that and then choose the EXIF tab, you can see Date Time Original data.

Looks like this:

You can see the date you're interested in by using the Columns view in the Finder:

Sure. That content created date will only reflect the EXIF DateTimeOriginal under the circumstances I mentioned earlier. Since the Preview options do not offer DateTimeOriginal or DateTimeDigitized choices, one has no way to determine if the Finder's displayed date correlates with the EXIF data, or system date/time stamp — unless you know A Priori that the image was brought into the Mac via Image Capture.

I have a short AppleScript that extracts EXIF (if available) data from an image, and then writes that DateTimeOriginal string as a Finder comment for the image.

You are welcome. Its the Finder Preview feature I mentioned in my original reply.
