iLifeiPhoto did the same.
There are two kinds of metadata involved when you consider jpeg or other image file.
One is the file data. This is what the Finder shows. This tells you nothing about the contents of the file, just the File itself.
The problem with File metadata is that it can easily change as the file is moved from place to place or exported, e-mailed, uploaded etc.
Photographs have also got both Exif and IPTC metadata. The date and time that your camera snapped the Photograph is recorded in the Exif metadata. Regardless if what the file date says, this is the actual time recorded by the camera.
Photo applications like iPhoto, Aperture, Lightroom, Picasa, Photoshop etc get their date and time from the Exif metadata.
When you export from iPhoto or Photos to the Finder new file is created containing your Photo (and its Exif). The File date is - quite accurately - reported as the date of Export.
However, the Photo Date doesn't change.
The problem is that the Finder doesn't work with Exif.
So, your photo has the correct date, and so does the file, but they are different things. To sort on the Photo date you'll need to use a photo app.

Apr 27, 2015 2:12 PM in response to Frédéric De Lamotteby léonie,I'm sorry but I want is to export the corrected, cropped or enhanced pictures with the original creation date … like iPhoto used to do
iPhoto does also export edited image versions with the creation date of the day of the export. The original capture date is stored in the the EXIF tags of the photo. just like Photos does. You can see the capture date for example in Preview's Info panel.
Exporting an edited version creates a new file, and that will have a new creation date.

Well, I don't have iPhoto right now to test that but I'm pretty sure I was able to get pix out of iPhoto with their "good" date
That's puzzling

Which is the reason I never used iPhoto.
The problem is that the Finder doesn't work with Exif.
The great pity is that the Finder USED to work with the Exif, and the File Creation Date stayed the same no matter how often you moved or copied the file. I have 1000's of photos taken on different cameras with the correct File Creation Date that have moved from camera to computer to new computer and have all kept their correct creation date and time.
BUT now that I've "updated" to Lion, the Finder does not seem to be able to figure any of this out and all of my new photos transferred from phone and camera have the TRANSFER dates, not the date the file was created in the camera or phone. The old photos have the correct creation date, but the new ones do not.
This is VERY annoying when trying to put together a slide show on my laptop, or other applications.
It's regrettable to me that Apple has made everything much less user friendly, and much more difficult.

Jul 22, 2015 12:07 AM in response to Ellyenneby Terence Devlin,The Finder never worked with Exif, which is Photo metadata, it used and uses the File Metadata, which is quite a different thing. You were lucky not to face this issue before. But your case illustrates precisely why Exif was created. Do you have a query about Photos for Mac?

Aug 8, 2015 3:00 PM in response to Ellyenneby sgusa3,I ran into the same problem today but found out that I could solve it by selecting the second option "Export Unmodified Original" under the iPhoto/File/Export tab, instead of the first option "Export XX Photos". This way the new photo file on my Finder folder shows the original Created date when the photo was taken, not today's date. My system is OS X Yosemite, v10.10.4. Hope that helps.

Aug 8, 2015 4:01 PM in response to sgusa3by Terence Devlin,But not much use if you want to export an version of your Photo that has been edited...

Sep 19, 2016 9:00 PM in response to Ellyenneby Cogmire,I agree. Apple sometimes just makes it difficult to do something simple, like copy a file, when it doesn't follow the way they think it should be done. When a photo is taken a file is also created so they should have the same datettime. When a user copies a file from one folder to another file hasn't changed. So why modify the datetime it was created? IMO this is stupid.

Ditto - I can confirm no change between iPhoto and Photos for this
and no change in the user misunderstanding between photo dates and file dates since iPhoto either

No, copying a file is easy as pie, like any other OS.

And they do.

True and the date and time on the file don't change either. However, at no point here does any talk about copying a file. This thread is about exporting an image from a database, which is a very different thing.
