All credit goes to the wedding photographers as they are the one responsible to capture all the finest moments without getting tired. Without them it is almost impossible to capture the bride and groom at their best on their wedding day. It is quite natural that the wedding couples rush to share their newly photographed wedding pictures to friends and relatives through all ways like e-mail, posting on wedding sites and blogs, sending pictures via cell phones, a CD, or even the internet. Thus the wedding pictures tend to travel larger distances and compliments queue up.
The most popular wedding photography format is the JPEG format. JPEG has quite a few hidden levels of data and information that most users are not aware of. JPEG has quite a few latent levels of data and information that most users do not realize exist. Metadata is intended to help the user to further define the characteristics of a photograph or digital image. In some cases, metadata information may be of a sensitive nature. Metadata is embeddable by both JFIF (JPEG File Interchange Format) and Exif (Exchangeable Image File Format), which allow for various forms of encapsulated information in a JPEG file. The JFIF format was necessary to create files from JPEG data. JFIF was originally designed by Eric Hamilton. This format allowed JPEG data to be shared across platforms. This format boasted many features, some of which include: JPEG compression, PC / Mac / UNIX compatibility, YCbCr color space, and many other features. Meanwhile The Exif format is almost universally followed by wedding photographers using digital cameras. Exif was created by the JEIDA (Japan Electronic Industry Development Association). The Exif specification uses the existing JPEG file format, adding a special feature called metadata tags. This is where a JPEG file can contain many levels of information. Other specifications that embed metadata include:
– IPTC headers (International Press Telecommunications Council.
– XMP (Extensible Metadata Platform) from Adobe.
Given below are the types of information that may be embedded in a JPEG file:
– Copyright Information.
– Image manipulation software used: (Photoshop, Paintshop, Corel Draw).
– Text comments.
– GPS location (Global Positioning Satellite).
– Serial numbers.
