How can I capture the original file creation date of an image file that's been uploaded to the blobstore?
All similar questions/answers seem to refer to the upload date of the image. I'm interested in the date at which (in this case) the photo was taken.
Btw, my apologies if this is a total newb question.
Browsers won't send the file creation date when uploading images, so you won't have it on the server side (whether you use AppEngine/Blobstore or not).
For photos though, cameras generally save the date within the file, as EXIF metadata (or IPTC or XMP). I don't know if there's any API usable in AppEngine that'd allow you to access the EXIF metadata.
