Bridge 'description' and 'description writer' in metadata question

@rudy dupont – This is the Photoshop forum, however, this applies equally to Bridge or Photoshop.

In settings such as journalism, metadata is entered in the appropriate fields as described below by the IPTC.

In "personal use" settings, metadata is often entered in various fields regardless of "IPTC best practices".

From the horse's mouth:

Description/Caption

The Description field, often referred to as a ‘caption', is used to describe the who, what (and possibly where and when) and why of what is happening in the photograph. It can include people’s names, their roles in the action, and location information. Geographic location details should also be entered in the Location fields. The amount of detail included will depend on the image and whether the image is documentary or conceptual. Typically, editorial images come with complete caption text, while advertising images may not.

The Description field should not be confused with the field for Alt Text (Accessibility), see below.

This field is limited by the IIM format to about 2000 characters. In XMP there is effectively no character limit.

Description Writer

The name of the most recent person(s) involved in creating, editing or correcting the entries for the Description, Alt Text (Accessibility), or Extended Description (Accessibility) fields of the image. There may be more than one person writing descriptions for the image. In this case, make sure to specify the descriptions each writer worked on. For example, Description: Jane Doe; Alt Text and Extended Description: John Doe.

This field is limited by the IIM format to about 32 characters. In XMP there is effectively no character limit.
