Many cameras record EXIF (Exchangeable Image File Format) information in photos. This information includes the camera make and model, the date and time the photo was taken, and camera settings, such as orientation, exposure time, and ISO speed. You can add and edit EXIF information.
If you plan to sell or widely distribute your photos, you should consider editing the IPTC (International Press Telecommunications Council) information of your photos. This information includes captions, keywords, and photographer credits, and would have been added in a photo management application, like ACDSee.
