export photos withe their creation dates

the exported original files are always larger than those edited photos you directly exported

Not necessarily. It is possible to export an image and end up with a file larger than the original in some cases using jpegs. Odd but possible. It just means the new file has less compression applied than the original.

I've had this problem too and I am also interested if someone has solved this with a batch tool but here's my learnings to date...

There's a difference between the OS level file "created date" and the EXIF "created date", The EXIF information is stored IN the photo where the latter is at the OS level. When dealing with Photo's you most likely care about the date the file was taken not the OS level file date it was copied form the camera/SD card. Depending on what you intend to do with the photo's, your next tool may solve for this problem (Capture One lets you import and file based on the EXIF date taken data). Otherwise, like scanned photo's (file date at the OS level is likely not the date the photo was taken) I don't think there is a great batch file 'fix'. There are tools that will look at the EXIF and change the actual file name to append the EXIF date to the filename but chasing the OS level 'creation date' in a batch form is still a mystery to me and I believe unrealistic to pursue for photo's.

Let me know your thoughts and how you solve for this if you do...

iPhoto 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.

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 do and it doesn't.

Which is the reason I never used iPhoto.

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.

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?

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.

But not much use if you want to export an version of your Photo that has been edited...

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.

it works and the exported original files are always larger than those edited photos you directly exported( with that date problem).

There are apps that will read the Exif and use it to patch the file date. For instance:
