Hello everyone, today we will talk about Metadata. I get asked about Metadata quite a lot and here is the explanation for everyone.
Metadata in its simplest explanation is “data about data”. Metadata is a structured information about the original primary data which can come from your digital camera just to give an example. Many different industries use Metadata but we will focus on digital imaging here.
Metadata information can be found in Photoshop as File Info command under File Menu. It is an Adobe implementation of the IPTC specification (IPTC is International Press and Telecommunications Council, they originally deployed metadata). One of the categories in File Info is Decription which is used to append metadata to the images. The information that can be entered here is Copyright Information, Copyright URL, Keywords, Description, Author Name and Title etc.
Camera Data category contains all the information from the camera (EXIF data). EXIF was designed to embed at the moment of exposure all the information relating to camera’s function and image parameters. The information found here are: Camera Make and Model, Shutter Speed, Exposure, ISO Rating, Lens incl. focal length and Flash information.
Some of the Metadata information is editable, f.ex. Description and IPTC while others are not f.ex. Camera Data. This means that information about the author, copyright and description can be easily deleted by anyone using Photoshop and then saved with the file, f.ex. an image can be marked as Unknown instead of Copyrighted.
File Info dialog box can be now found across all Creative Suite 4. Metada can also be quickly added to the whole set set of images in Adobe Bridge or Adobe Photoshop Lightroom.
