Mac Finder dates and exif dates
You can create your own service in automator to provide this info in a popup.


Create a New Service in Automator and set it so the service receives image files in Finder
Add a Run Shell Script Action. Pass input as argument. One-liner shell script should be (depending on your path to exiftool) /usr/local/bin/exiftool -b -DateCreated $1
Pass the result into a Set Value of Variable Action. Create a new variable (I called mine EXIFDateCreated
Add a Get Value of Variable and select the variable you created above. Make sure to check the Ignore this actions input (...the first time you use this action, to separate the creation of variables chain from the getting. You can repeat the above steps numerous times to add other files you want to display, but for subsequent Get Value of Variables you would not ignore input).
Add a Run AppleScript Action the AppleScript could be:



    on run {input, parameters}
        set dateCreated to first item of input as text
        display dialog "Date Created: " & dateCreated

        return input
    end run


Here's a screen cap of the whole Automator service...

Save the Service as something like "Show EXIF Create Date" and make sure it is activated in the Keyboard Preferences (Under the Shortcuts tab). The action should now show up when you right click/command click on an image in the finder.

Note this can be tweaked to create a pretty decent alternate Info dialog, though this just shows the basics of how it can come together.
