Adobe Photoshop CS5 for Photographers - Martin Evening [256]

If the history log options have been enabled in the Photoshop General preferences, the history log content can record: sessions only (such as the time a file was opened and closed); a concise log listing of what was done in Photoshop; or as shown here, a detailed log that includes a comprehensive list of the settings applied at every step. If you choose to embed the history log in the file metadata, the edit history log can be viewed via the Bridge Metadata panel.
Hidden metadata
Lastly, I should mention that there may be hidden metadata that won't show up in any of the Metadata panel sections. This could be things like camera manufacturer EXIF metadata that contains proprietary information that only the camera manufacturer's software has access to.
Keywording
Keywording provides you with a way to group and organize images within Photoshop. By using keyword tags to describe the image content, you can catalog your files more comprehensively.
Where keywords are stored
Like other metadata, keyword information (including the keyword hierarchy) is stored directly in the file's XMP space, or in the case of raw files, either to the Camera Raw cache database or as a sidecar file. The Keywords panel displays the accumulated information that it has read from various image files’ metadata and can also be used to write keyword metadata back to the files.
Other keywords
As you enter keywords via the File Info panel, any keywords that are unrecognized will appear listed under the category: ‘Other Keywords’. You can then use the Keywords panel to rearrange these into a suitable hierarchy and have the option to make them persistent. You will also find that where Bridge is unable to read the hierarchy of keywords that have been entered via another program, these too may appear listed under ‘Other keywords’.
It is usually best to add keywords at the same time as you import new images. For example, Figure 11.48 shows a detailed view of the Categories section of the File Info dialog where you can add keywords to an image. It is important to note here that each keyword must be separated by a semicolon or a comma. This is important as it ensures the keywords are clearly separated (see how the keywords are entered in Figure 11.48). Such keyword metadata can also be included when you create a metadata template. For example, every time you shoot a particular sporting event you might want to have a template that applies relevant keyword metadata you always need for these types of assignments, such as the name of the stadium location and home team. Unfortunately, you can't create a keyword hierarchy as you enter the keywords (see sidebar on ‘Other keywords’). You also need to know the exact keyword phrases to type if they are to match with the keyword data used elsewhere for other images, which is why it is sometimes better to use the Keywords panel to do this.

Keywords panel
The Keyword panel (Figure 11.49) displays all the keywords that are associated with the images you have currently selected. The Keywords panel provides a basic level of organization as it allows you to arrange keywords that you come across into a hierarchy list, plus you can also use the Keywords panel to add new keywords. Click on the ‘Add new keyword’ button to create a keyword category, such as ‘People’ or ‘Places’, type in the name and hit to add the keyword (or use to cancel). You can then highlight the keyword and click on the ‘Add new sub keyword’ button to add a new sub keyword. Once keywords appear listed in the Keywords panel you can make a thumbnail selection within Bridge, go to the Keyword panel and click on the empty square to the left of the desired keyword to apply, or click again to remove. This method allows you to assign one or more keywords to multiple
