It has been found that some of the most popular social media sites will delete a photograph's metadata.
Research undertaken by the International Press Telecommunications Council showed that sites such as Facebook, Twitter and Flickr will remove photographer's metadata from images that they host.
The IPTC tested a total of 15 social media websites, with an aim to find out how image sharing through upload and download effects the embedded metadata of an image.
Flickr and Facebook were found to remove most of the metadata from images uploaded, while Google + came out on top, retaining all types of metadata in its images.
