What are the benefits of having Image Metadata?

Feb 2014 - From Matt Cutts: https://www.youtube.com/watch?v=GMf6FmRus2M

"The short answer is we did a blog post in April 2012 where we talked about it and we did say we reserve the right to use EXIF or other sort of meta data that we find an image in order to help people find information," Cutts said. "And at least in the version of image search as it existed back then, when you clicked on an image we would sometimes show the information from EXIF data in the right-hand sidebar. So it is something that Google is able to parse out and I think we do reserve the right to use it in ranking."
