Unfortunately, Google+ gallery pictures don't include the EXIF information. You have to use the "Download Original" option when you click on the picture. Even though it says ORIGINAL, you will be downloading a smaller size image.

I was, however, very pleased with the way this image appeared in the instant upload section of Google+. I did nothing to it. It shows, very well, how there is more detail outside the windows than there would be if I hadn't set the camera to HDR mode. It's very helpful for backlit picture.
