Title: METADATA/IPTC/EXIF/XMP #1
Post by: Laura Shook on 2015-10-14 18:03:18
Metadata is information stored about a file, usually stored within it. For example, metadata about an image may include such things as:

Who created it.

A description of the image.

When was it created.

What were the camera settings.

Who may  use it.

Overview:

Metadata is known as and includes various types of information, including XMP, File Info (Photoshop), EXIF and IPTC.

The most common file metadata formats and names are:

XMP:

An extensive, rich, and extensible standard for storing all kinds of metadata in files of many different formats. It encompasses and effectively supersedes many earlier format-specific metadata standards, including EXIF and IPTC.

EXIF:

Information from a digital camera or scanner when the image is created (or modified manually). EXIF is the name for a metadata standard originally based on tags from the TIFF file format, with extensions, that could be stored in TIFF and other file types. Today EXIF is most often stored as XMP.

IPTC:

Information supplied by a news agency or source and included with the image to make it easy to find who created it, why it was created, how it may be used, and so on. IPTC was originally stored in a block of information with its own format. Because IPTC included many fields applicable to wide use, and because it was the first real codified and supported standard, it was adopted widely for other uses. Today, like EXIF, it is stored as XMP.

Photoshop:

Photoshop has always had a File Info function which allows you to set up metadata. Most of its original fields were based on the original IPTC standard.
